    Mechanisms for ground-surface fracturing and incipient slope failure associated with the 2001 eruption of Mt. Etna, Italy: analysis of ephemeral field data (2008)
    Elsevier
    Details
    Publikationsdatum: 2020-11-26
    Beschreibung: During the July^August 2001 eruption of Mt. Etna development of extensional fractures/faults and grabens accompanied magma intrusion and subsequent volcanic activity. During the first days of the eruption, we performed an analysis of attitude, displacement and propagation of fractures and faults exposed on the ground surface in two sites, Torre del Filosofo and Valle del Leone, located along the same fracture system in the region surrounding the Valle del Bove depression on the eastern flank of Mt. Etna. Fractures and faults formed as the consequence of a shallow intruding dyke system that fed the several volcanic centres developed along the fracture system. The investigated sites differ in slope attitude and in geometrical relationships between fractures and slopes. In particular, the fracture system propagated parallel to the gentle slope (67‡ dip) in the Torre del Filosofo area, and perpendicular to the steep slope (V25‡ dip) in the Valle del Leone area. In the Torre del Filosofo area, slight graben subsidence and horizontal extension of the ground surface by about 3 m were recorded. In the Valle del Leone area, extensional faulting forming a larger and deeper graben with horizontal extension of the ground surface by about 10 m was recorded. For the Valle del Leone area, we assessed a downhill dip of 14‡ for the graben master fault at the structural level beneath the graben where the fault dip shallows. These results suggest that dyke intrusion at Mount Etna, and particularly in the region surrounding the Valle del Bove depression, may be at the origin of slope failure and subsequent slumps where boundary conditions, i.e. geometry of dyke, slope dip and initial shear stress, amongst others, favour incipient failures.

    Structural features of the July–August 2001 Mount Etna eruption: evidence for a complex magma supply system (2008)
    Geological Society of London
    Details
    Publikationsdatum: 2020-11-26
    Beschreibung: We describe the evolution of the volcanic activity and deformation patterns observed at Mount Etna during the July–August 2001 eruption. Seismicity started at 3000 m below sea level on 13 July, accompanied by moderate ground swelling. Ground deformation culminated on 16 July with the development of a NE–SW graben c. 500 m wide and c. 1 m deep in the Cisternazza area at 2600–2500 m above sea level on the southern slope of the volcano. On 17 July, the eruption started at the summit of Mount Etna from the SE Crater (central–lateral eruptive system), from which two radial, c. 30 m wide, c. 3000 m long fracture zones, associated with eruptive fissures, propagated both southward (17 July) and northeastward (20 July). On 18 July, a new vent formed at 2100 m elevation, at the southern base of the Montagnola, followed on the next day by the opening of a vent further upslope, at 2550 m (eccentric eruptive system). The eruption lasted for 3 weeks. Approximately 80% of the total lava volume was erupted from the 2100 m and the 2550 m vents. The collected structural data suggest that the Cisternazza graben developed as a passive local response of the volcanic edifice to the ascent of a north–south eccentric dyke, which eventually reached the ground surface in the Montagnola area (18–19 July). In contrast, the two narrow fracture zones radiating from the summit are interpreted as the lateral propagation, from the conduit of the SE Crater, of north–south- and NE–SW-oriented shallow dykes, 2–3 m wide. The evolution of the fracture pattern together with other volcanological data (magma ascent and effusion rate, eruptive style, petrochemical characteristics of the erupted products, and petrology of xenoliths within magma) suggest that the eccentric and central–lateral eruptions were fed by two distinct magmatic systems. Examples of eccentric activity accompanied by central–lateral events have never been described before at Etna.

    Continuous monitoring of soil CO2 flux on Mt. Etna:The 2004–2005 eruption and the role of regional tectonics and volcano tectonics. (2008)
    American Geophysical Union
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The soil CO2 flux on Mt. Etna as recorded by the ETNAGAS network (an automatic system for measuring soil CO2 flux and meteorological parameters) started to increase strongly about 5 months prior to the onset of the 2004–2005 eruption and decreased a few months before the end of the eruption. Time delays in the occurrences of anomalies in soil CO2 flux at different sites in the geochemical network constrain the relationship between soil CO2 flux distributions and the tectonic framework of Etna volcano. The anomalies observed before the 2004–2005 eruption support the intrusion of new undegassed magma into the upper feeding system of the volcano (〈20 km below sea level). Magma subsequently rose slowly in the volcano conduits, thereby triggering the onset of the 2004–2005 eruption. The time delays in the occurrences of anomalies in combination with spectral analysis indicate the importance of tectonic and volcanotectonic structures in driving the ascent of deep gases within the crust. Moreover, greatest amplitude pulsations of the low-frequency components of the CO2 flux signals were correlated with the paroxystic activities of the 2004–2005 eruption. This study confirms that CO2 flux variation is a useful indicator for volcanic activity in the surveillance of the Mt. Etna and similar basaltic volcanoes.

    Imaging the polarity switch between large seismogenic normal faults in the southern Apennines (Italy) (2008)
    Details
    Publikationsdatum: 2012-02-03
    Beschreibung: The transition between the central and southern Apennines (Italy) is marked, among other regional features, by a dramatic shift (from SW-dipping to NE-dipping) of the verging of the large (25+ km long) seismogenic normal faults, responsible for M〉6 pre-historical and historical earthquakes. Also, in the exact area where such accommodation occurs, in 2005 a low magnitude (M〈3) seismic sequence took place along a short stretch of a long-lived transverse structure Running across this transition zone. We believe this sequence sheds light on the geometry and the role of the interaction between these seismogenic domains.

    Genesis and geomorphologic and ecological evolution of the Ganzirri salt marsh (Messina, Italy) (2008)
    elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The results of geological and geomorphologic surveys on the salt marsh of Ganzirri (Pantano Grande), combined with geophysical researches and historiographical data, are reported here to define the genesis of the marsh and to evaluate the physical factors that influenced its recent evolution. The genesis of the Pantano Grande may be due to a state of equilibrium reached between differential lowering of the coastal plain, confined by normal faults, and generalized chain uplift. In particular, two normal faults are considered: the first borders the northern shore of the Pantano Grande, and the second bounds the Ionian coastal plain towards the south. Concerning the recent evolution of the Pantano Grande the importance of the sterile conglomerate outcrop, which borders the Ganzirri coastal plain, is stressed. The conglomerate is interposed between sediments that define the Pantano Grande basin, and the Ionian Sea, and influenced the water exchange between the marsh and the sea. Before the excavation of two canals that link up the Pantano Grande with the sea, the conglomerate, limiting the spread of benthic species, has definitively affected the ecological structure of the original marsh.

    Thick-skinned tectonics in the external Apennines, Italy: New evidence from magnetic anomaly analysis (2008)
    AGU
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: We discuss the tectonic implications of a new residual magnetic map of the Apennine belt/Adriatic-Apulian foreland obtained by integrating ground and offshore data sets [Chiappini et al., 2000a]. Negative anomalies are documented over the Adriatic-Apulian foreland areas, whereas the external Apennine belt is characterized by a ubiquitous lowamplitude (〈30 nT), long-wavelength positive anomaly. In the central northern Apennines, three 100 km wide more intense (100–200 nT) round-shaped anomalies are superimposed to the long-wavelength feature. Finally, in the Tyrrhenian Sea and margins, high-intensity, short-wavelength positive-negative couplets coincide with magmatic outcrops or bodies at shallow depth. The low-amplitude anomaly pattern over Italy suggests that the magnetic basement beneath the Triassic evaporites is ubiquitously incorporated in the external belt compressive fronts, implying a thick-skinned tectonic style for the external Apennines. The new residual magnetic map resolves the inconsistency between previous aeromagnetic data [AGIP SpA. Italia, 1981], which suggested a lack of basement involvement in the Apennine belt, and recent seismic data, which imaged deep reflectors penetrating the basement. Two magnetic models along NE-SW transects in the northern and southern Apennines suggest consistent structural styles. In the northern Apennines, positive anomalies roughly coincide with the external compressive fronts, although there are local second-order differences between the belt front and the edges of the anomaly. Here the magnetic data show that the basement rises southwestward along the thrust fronts from 6–7 km depth in the Adriatic foreland to 2–3 km depth in the axial belt, where some exploration wells have penetrated basement. Within the belt front, basement exhumation is inferred to occur along high-angle, low-displacement thrust faults inverting preexisting normal faults. In the southern Apennines, a remarkable positive magnetic anomaly is parallel with and tens of kilometers southwest of the belt front. Seismic data and oil wells show that the basement surface cannot be shallower in the belt than in the foreland. Therefore the observed magnetic anomaly is produced by strongly magnetic basement beneath the belt, likely an internal crustal wedge tectonically interposed between the Apulian carbonate sequences and basement.

    Belt bending driven by lateral bending of subducting lithospheric slab: geophysical evidences from the northern Apennines (Italy) (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Many of the mountain belts displaying a curved shape are "oroclines", i.e. are produced after progressive bending of an originally straight fold and thrust belt. The bending process was previously explained as a consequence of several possible events taking place in the crustal orogenic wedge, such as occurrence of obstacles, non-coaxial deformation, and mouvements on wrench faults. Recent paleomagnetic results from the northern Apenninic Arc document that this belt is properly an orocline and results from Late Messinian-Early Pliocene bending of a Messinian straight belt-foredeep system. Tomographic images in turn show the presence of a high-velocity body, interpreted as subducted slab, in the upper mantle beneath the northern Apennines, between 35 and 670 km depth. Down to 100 km, this body displays an arcuate shape which closely mirrors the geological outlines, while it appears to be straight (and parallel to the Messinian pre-rotated belt) at depth. We explore here the possibility that the arcuate shape of the northern Apennines is a consequence, closely following in time, on much deeper processes than previously suggested, i.e. the lateral bending of the subducting Adriatic plate.

    Tectonics of the Umbria-Marche-Romagna Arc (central northern Apennines, Italy): New paleomagnetic constraints (2008)
    AGU
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: We present the results of a paleomagnetic study carried out on 32 sites from mainly Messinian clayey sediments distributed throughout the external Umbria-Marche-Romagna Arc (UMRA). These data, together with published results from coeval sediments, demonstrate that this arc is an orocline in its central northern sector. Bending, not well constrained in time, was due to about 15° clockwise rotations of the central part of this arc and to counterclockwise rotations farther north. In this latter area, post-Messinian counterclockwise rotations are of the same amplitude as those calculated for some classic Mesozoic paleomagnestic sections in northern Umbria, suggesting a Plio-Pleistocene age for the rotations reported from the older sequences.

    Transpressive strain on the Lipari–Vulcano volcanic complex and dynamics of the “La Fossa” cone (Aeolian Islands, Sicily) revealed by GPS surveys on a dense network (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Ground deformation resulting from the last two GPS surveys carried out in March 2006 and September 2007 on the Lipari–Vulcano volcanic complex are analyzed. Data inversion was performed by Genetic Algorithms approach, using the horizontal strain measured on 258 GPS baselines, in order to avoid bias due to the ambiguity in fixing the reference system and to disregard the vertical deformation of the “La Fossa” cone. There are two networks in this area: the main Lipari–Vulcano network and the denser Vulcano–Nord one. Surveying strategies adopted for the main network during the latest surveys allowed long baselines, from Lipari and Vulcano to the surrounding permanent stations in the southern Tyrrhenian, to be processed with reliable accuracy. The fast-static strategy was instead adopted to survey the Vulcano–Nord network. Data from the main Lipari–Vulcano network has been processed in the ITRF05 frame and also in a local reference frame together with the Vulcano–Nord data. A significant Northward motion of Vulcano island with respect to the ITRF05 has been detected. This motion abruptly decreases in the northern part of Vulcano, suggesting a decoupling of the main Vulcano island from the rest of the volcanic complex. The analysis in the local reference frame evidenced a relative SSE-ward motion of Lipari and Northern part of Vulcano, with respect to the central and southern Vulcano. This comparison also highlights a local uplift of the “La Fossa” cone. In addition, a strain tensor analysis was performed, which highlighted a main NNE–SSW contraction and a minor ESE–WNW extension detected only on the southern part of Vulcano. This results are in agreement with a transpressive kinematics of the Lipari–Vulcano volcanic complex, with a main dextral component of displacement along a NW–SE striking structure.

    Middle Pleistocene to Holocene activity of the Gondola Fault Zone (Southern Adriatic Foreland): deformation of a regional shear zone and seismotectonic implications (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Recent seismicity in and around the Gargano Promontory, an uplifted portion of the Southern Adriatic Foreland domain, indicates active E–W strike-slip faulting in a region that has also been struck by large historical earthquakes, particularly along the Mattinata Fault. Seismic profiles published in the past two decades show that the pattern of tectonic deformation along the E–W-trending segment of the Gondola Fault Zone, the offshore counterpart of the Mattinata Fault, is strikingly similar to that observed onshore during the Eocene–Pliocene interval. Based on the lack of instrumental seismicity in the south Adriatic offshore, however, and on standard seismic reflection data showing an undisturbed Quaternary succession above the Gondola Fault Zone, this fault zone has been interpreted as essentially inactive since the Pliocene. Nevertheless, many investigators emphasised the genetic relationships and physical continuity between the Mattinata Fault, a positively active tectonic feature, and the Gondola Fault Zone. The seismotectonic potential of the system formed by these two faults has never been investigated in detail. Recent investigations of Quaternary sedimentary successions on the Adriatic shelf, by means of very high-resolution seismic–stratigraphic data, have led to the identification of fold growth and fault propagation in Middle–Upper Pleistocene and Holocene units. The inferred pattern of gentle folding and shallow faulting indicates that sediments deposited during the past ca. 450 ka were recurrently deformed along the E–W branch of the Gondola Fault Zone. We performed a detailed reconstruction and kinematic interpretation of the most recent deformation observed along the Gondola Fault Zone and interpret it in the broader context of the seismotectonic setting of the Southern Apennines-foreland region. We hypothesise that the entire 180 km-long Molise–Gondola Shear Zone is presently active and speculate that also its offshore portion, the Gondola Fault Zone, has a seismogenic behaviour.

    Beschreibung: Southern Apulia (Adriatic foreland, Italy), has long been considered a “stable area” lying in between two active orogens, but in fact its tectonic framework is poorly known. To learn more about this topic, we carried out an original structural analysis on Pleistocene deposits. The results indicate that southern Apulia has been affected by mild but discernible brittle deformation throughout the Middle and Late Pleistocene. Joints prevail, whereas faults are rare and all characterized by small displacement. Horizontal extension dominates throughout the entire study area; the SW-NE to SSW-NNE direction is the most widespread. WNW-ESE extension prevails in the Adriatic side portion of the study area, but the dispersion of the measured plane directions is high, suggesting that the local strain field is not characterized by a strongly predominant trend. A Middle and Late Pleistocene, SW-NE to SSW-NNE– oriented maximum extension is not surprising for the study area, as it is compatible with most of the available geodynamic models, whereas the different state of deformation affecting the Adriatic side of the study area requires further investigations. We tentatively interpreted this anomaly as reflecting some regional variation of the general geodynamic frame, for instance as the farthest evidence of ongoing compressional deformation across the W-verging Albanide-Hellenide foldand- thrust belt.

    Intrusion of eccentric dikes: The case of the 2001 eruption and its role in the dynamics of Mt. Etna volcano (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The 2001 eruption represents one of the most studied events both from volcanological and geophysical point of view on Mt. Etna. This eruption was a crucial event in the recent dynamic of the volcano, marking the passage from a period (March 1993 – June 2001) of moderate stability with slow, continuous flank sliding and contemporaneous summit eruptions, to a period (July 2001 to present) of dramatically increased flank deformations and flank eruptions. We show new GPS data and high precision relocation of seismicity in order to demonstrate the role of the 2001 intrusive phase in this change of the dynamic regime of the volcano. GPS data consist of two kinematic surveys carried out on 12 July, a few hours before the beginning of the seismic swarm, and on 17 July, just after the onset of eruptive activity. A picture of the spatial distribution of the sin-eruptive seismicity has been obtained using the HypoDD relocation algorithm based on the double-difference (DD) technique. Modeling of GPS measurements reveal a southward motion of the upper southern part of the volcano, driven by a NNW-SSE structure showing mainly left-lateral kinematics. Precise hypocenter location evidences an aseismic zone at about sea level, where the magma upraise was characterized by a much higher velocity and an abrupt westward shift, revealing the existence of a weakened or ductile zone. These results reveal how an intrusion of a dike can severely modify the shallow stress field, triggering significant flank failure. In 2001, the intrusion was driven by a weakened surface, which might correspond to a decollement plane of the portion of the volcano affected by flank instability, inducing an additional stress testified by GPS measurements and seismic data, which led to an acceleration of the sliding flanks.

    Structural features of the 2007 Stromboli eruption (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: On 27 February 2007, two NE–SW and NNW–SSE dike-fed effusive vents opened to the North (at 650 and 400 m above sea level, asl) of the summit craters at Stromboli, forming a fissure parallel to the inner walls of the Sciara del Fuoco (SdF) sector collapse depression. The formation of these vents was soon followed by rapid subsidence of the summit crater area. This partly obstructed the central conduit, temporarily choking the fissure and increasing the deformation of the upper part of SdF. The reactivation of the NNW–SSE vent and the opening of a new vent located at 500 m asl, fed by a second dike, released the internal pressure and surface deformation ceased. The eruption then continued again from the 400 m vent, after a summit explosion on 15 March, until ending in early April after a progressive decrease of magma output. Repeated NE–SW dike intrusions have occurred in recent years, close to the upper SE limit of the SdF. In that zone, named Bastimento, the eruptive fractures traced the discontinuities that borders the SdF, increasing the risk of triggering new sector collapse. Whereas the NE–SW trending structures lie along the regional volcanostructural trend of the Aeolian arc through Stromboli, the NNW–SSE vents are oblique to this trend and may be controlled by the anomalous stress field within the unstable flank of the SdF. Another fundamental aspect of the 2007 eruption is the collapse of the central conduit, due to the rapid and deep magma drainage linked to the opening of the 400 m vent. The intrusion of dikes and development of flank vents during the 2007 eruption could possibly have triggered catastrophic landslides and related tsunami or eruptive paroxysms, but the opening of new effusive vents released the internal pressures, diminishing the hazard.

    Comparison between different methodologies for detecting Radon in soil along an active fault: the case of the Pernicana fault system, Mt. Etna (Italy) (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Three different methodologies were used to measure Radon (222Rn) in soil, based on both passive and active detection system. The first technique consisted of Solid State Nuclear Track Detectors (SSNTD), CR-39 type, and allowed integrated measurements. The second one consisted of a portable device for short time measurements. The last consisted of a continuous measurement device for extended monitoring, placed in selected sites. Soil 222Rn activity was measured together with soil Thoron (220Rn) and soil carbon dioxide (CO2) efflux, and it was compared with the content of radionuclides in the rocks. Two different soil gas horizontal transects were investigated across the Pernicana fault system (NE flank of Mount Etna), from November 2006 to April 2007. The results obtained with the three methodologies are in a general agreement with each other and reflect the tectonic settings of the investigated study area. The lowest 222Rn values were recorded just on the fault plane, and relatively higher values were recorded a few tens of meters from the fault axis on both of its sides. This pattern could be explained as a dilution effect resulting from high rates of soil CO2 efflux. Time variations of 222Rn activity were mostly linked to atmospheric influences, whereas no significant correlation with the volcanic activity was observed. In order to further investigate regional radon distributions, spot measurements were made to identify sites having high Rn emissions that could subsequently be monitored for temporal radon variations.. SSNTD measurements allow for extended-duration monitoring of a relatively large number of sites, although with some loss of temporal resolution due to their long integration time. Continuous monitoring probes are optimal for detailed time monitoring, but because of their expense, they can best be used to complement the information acquired with SSNTD in a network of monitored sites.

    Simultaneous magma and gas eruptions at three volcanoes in southern Italy: an earthquake trigger? (2008)
    Geological Society of America
    Details
    Publikationsdatum: 2017-04-03
    Beschreibung: In September 2002, a series of tectonic earthquakes occurred north of Sicily, Italy, followed by three events of volcanic unrest within 150 km. On October 28, 2002, Mt. Etna erupted; on November 3, 2002, submarine degassing occurred near Panarea Island; and on December 28, 2002, Stromboli Island erupted. All of these events were considered unusual: the Mt. Etna NE-rift eruption was the largest in 55 yr, the Panarea degassing was one of the strongest ever detected there, and the Stromboli eruption, which produced a landslide and tsunami, was the largest effusive eruption in 17 yr. Here, we investigate the synchronous occurrence of these clustered unrest events, and develop a possible explanatory model. We compute short-term earthquake-induced dynamic strain changes and compare them to long-term tectonic effects. Results suggest that the earthquake-induced strain changes exceeded annual tectonic strains by at least an order of magnitude. This agitation occurred in seconds, and may have induced fluid and gas pressure migration within the already active hydrothermal and magmatic systems.

    What makes flank eruptions? The 2001 Etna eruption and its possible triggering mechanisms (2008)
    Springer-Verlag
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Most flank eruptions within a central stratovolcano are triggered by lateral draining of magma from its central conduit, and only few eruptions appear to be independent of the central conduit. In order to better highlight the dynamics of flank eruptions in a central stratovolcano, we review the eruptive history of Etna over the last 100 years. In particular, we take into consideration the Mount Etna eruption in 2001, which showed both summit activity and a flank eruption interpreted to be independent from the summit system. The eruption started with the emplacement of a ~N-S trending peripheral dike, responsible for the extrusion of 75% of the total volume of the erupted products. The rest of the magma was extruded through the summit conduit system (SE crater), feeding two radial dikes. The distribution of the seismicity and structures related to the propagation of the peripheral dike and volumetric considerations on the erupted magmas exclude a shallow connection between the summit and the peripheral magmatic systems during the eruption. Even though the summit and the peripheral magmatic systems were independent at shallow depths (〈3 km b.s.l.), petro-chemical data suggest that a common magma rising from depth fed the two systems. This deep connection resulted in the extrusion of residual magma from the summit system and of new magma from the peripheral system. Gravitational stresses predominate at the surface, controlling the emplacement of the dikes radiating from the summit; conversely, regional tectonics, possibly related to N-S trending structures, remains the most likely factor to have controlled at depth the rise of magma feeding the peripheral eruption.

    Rotational differencies between the northern and southern Tyrrhenian domains: paleomagnetic constraints from the Amantea basin (Calabria, Italy) (2008)
    Geological Society of London
    Details
    Publikationsdatum: 2012-02-03
    Beschreibung: We report on a palaeomagnetic study of upper Miocene sediments from the Amantea basin, located on the Tyrrhenian coast of Calabria. The magnetic mineralogy is dominated by greigite and subordinate magnetite in the Tortonian-Messinian clays (ten sites), and by hemoilmenite and magnetite in the underlaying sands and volcanic ashes (three sites), which have not been dated. Data from the Tortonian, Messinian clays pass both a reversal and a fold test, and define a 19° ± 11° clockwise rotation (with respect to the geocentric axial dipole field direction) for the whole basin. The variable amounts of westward declinations observed in the underlaying sands and volcanic ashes can be due to (1) a large counterclockwise rotation episode occurring before the clockwise rotation, (2) the effects of a transitional geomagnetic field in these rapidly deposited sediments, or (3) the observed complex magnetic mineralogy. The new results, when compared with previous palaeomagnetic studies from other Calabrian basins, show that the Neogene drifting of the Calabro-Peloritan block from the eastern margin of Sardinia to the present-day position was accompained by a (probably Pleistocene) 15-20° rigid clockwise rotation recorded in both the Tyrrhenian and Ionian margins. This tectonic regime is shown to be very different from the one observed by previous studies in the northern Tyrrhenian domain, where large rotation associated with thrust sheet activity in the external Apennines were coeval with the onset of an irrotational extentional regime in the Tuscan and Latium Tyrrhenian margins. Palaeomagnetism thus confirms the significant geodynamical differences between the southern and northern Tyrrhenian Sea spreadings.

    Seismotectonics of strike–slip earthquakes within the deep crust of southern Italy: Geometry, kinematics, stress field and crustal rheology of the Potenza 1990–1991 seismic sequences (Mmax 5.7) (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: We present a revision and a seismotectonic interpretation of deep crust strike–slip earthquake sequences that occurred in 1990– 1991 in the Southern Apennines (Potenza area). The revision is motivated by: i) the striking similarity to a seismic sequence that occurred in 2002 ∼140 km NNW, in an analogous tectonic context (Molise area), suggesting a common seismotectonic environment of regional importance; ii) the close proximity of such deep strike–slip seismicity with shallow extensional seismicity (Apennine area); and iii) the lack of knowledge about the mechanical properties of the crust that might justify the observed crustal seismicity. A comparison between the revised 1990–1991 earthquakes and the 2002 earthquakes, as well as the integration of seismological data with a rheological analysis offer new constraints on the regional seismotectonic context of crustal seismicity in the Southern Apennines. The seismological revision consists of a relocation of the aftershock sequences based on newly constrained velocity models. New focal mechanisms of the aftershocks are computed and the active state of stress is constrained via the use of a stress inversion technique. The relationships among the observed seismicity, the crustal structure of the Southern Apennines, and the rheological layering are analysed along a crustal section crossing southern Italy, by computing geotherms and two-mechanism (brittle frictional vs. ductile plastic strength) rheological profiles. The 1990–1991 seismicity is concentrated in a well-defined depth range (mostly between 15 and 23 km depths). This depth range corresponds to the upper pat of the middle crust underlying the Apulian sedimentary cover, in the footwall of the easternmost Apennine thrust system. The 3D distribution of the aftershocks, the fault kinematics, and the stress inversion indicate the activation of a right-lateral strike–slip fault striking N100°E under a stress field characterized by a sub-horizontal N142°-trending σ1 and a sub-horizontal N232°-trending σ3, very similar to the known stress field of the Gargano seismic zone in the Apulian foreland. The apparent anomalous depths of the earthquakes (N15 km) and the confinement within a relatively narrow depth range are explained by the crustal rheology, which consists of a strong brittle layer at mid crustal depths sandwiched between two plastic horizons. This articulated rheological stratification is typical of the central part of the Southern Apennine crust, where the Apulian crust is overthrusted by Apennine units. Both the Potenza 1990–1991 and the Molise 2002 seismic sequences can be interpreted to be due to crustal E–W fault zones within the Apulian crust inherited from previous tectonic phases and overthrusted by Apennine units during the Late Pliocene–Middle Pleistocene. The present strike–slip tectonic regime reactivated these fault zones and caused them to move with an uneven mechanical behaviour; brittle seismogenic faulting is confined to the strong brittle part of the middle crust. This strong brittle layer might also act as a stress guide able to laterally transmit the deviatoric stresses responsible for the strike–slip regime in the Apulian crust and may explain the close proximity (nearly overlapping) of the strike–slip and normal faulting regimes in the Southern Apennines. From a methodological point of view, it seems that rather simple two-mechanism rheological profiles, though affected by uncertainties, are still a useful tool for estimating the rheological properties and likely seismogenic behaviour of the crust.

    The role of pre-existing thrust faults and topography on the styles of extension in the Gran Sasso range (central Italy) (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Structural analysis and field mapping together with simple geometrical and flexural elastic models, document that two styles of Quaternary extensional tectonics characterized the Gran Sasso range (central Apennines, Italy). In the western part of the range, extension took place on 10–15-km-long range-front normal faults with associated 600–1000-m-high escarpments showing evidence of Late Glacial–Holocene activity. This topography has been reproduced with a thin elastic plate subjected to the isostatic forces induced by the movement along high-angle (55°–65°) planar normal faults. In the eastern part of the belt extension occurred on shallow-dipping normal faults (30°–35°) which reactivated progressively deeper pre-existing thrusts. In this area antithetic "domino" faults formed to accommodate the mechanical adjustment of the hanging-wall over a variably dipping major fault surface. The eastward increase in shortening, due to the earlier compressional phase, documented in the Gran Sasso belt by previous authors, accounts for the more developed zones of weakness and high topographic relief in the eastern sector. This setting could explain the different styles of extension and the more advanced northeastern limit of normal faulting in the eastern sector. This work suggests that normal faults can originate either with low- or high-angle geometry in the upper crust according to the pre-existing tectonic setting and that topography could be important in controlling the geometry and pattern of migrating normal faulting.

    Dike propagation in volcanic edifices: Overview and possible developments (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Eruptions are often fed by dikes; therefore, better knowledge of dike propagation is necessary to improve our understanding of how magma is transferred and extruded at volcanoes. This study presents an overview of dike patterns and the factors controlling dike propagation within volcanic edifices. Largely based on published data, three main types of dikes (regional, circumferential and radial) are illustrated and discussed. Dike pattern data from 25 volcanic edifices in different settings are compared to derive semi-quantitative relationships between the topography (relief, shape, height, and presence of sector collapses) of the volcano, tectonic setting (presence of a regional stress field), and mean composition (SiO2 content). The overview demonstrates how dike propagation in a volcano is not a random process; rather, it depends from the following factors (listed in order of importance): the presence of relief, the shape of the edifice and regional tectonic control. We find that taller volcanoes develop longer radial dikes, whose (mainly lateral) propagation is independent of the composition of magma or the aspect ratio of the edifice. Future research, starting from these preliminary evaluations, should be devoted to identifying dike propagation paths and likely locations of vent formation at specific volcanoes, to better aid hazards assessment.

    Dike propagation within active central volcanic edifices: constraints from Somma-Vesuvius, Etna and analogue models (2008)
    Springer Berlin / Heidelberg
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Dikes within stratovolcanoes are commonly expected to have radial patterns. However, other patterns may also be also found, due to regional stresses, magmatic reservoirs, topographic variations. Here we investigate dike patterns within volcanic edifices, by studying dike and fissure complexes at Somma-Vesuvius and Etna (Italy) and using analogue models. At the surface, the dikes and fissures show a radial configuration. At depths of tens to several hundreds of m, in areas exposed by erosion, tangential and oblique dikes are also present. Analogue models indicate that dikes approaching the flanks of cones, regardless of their initial orientation, reorient to become radial (parallel to the maximum gravitational stress). This reorientation is a significant process in shallow magma migration and may also control the emplacement of dike-fed fissures reaching the lower slopes of the volcano.

    Possible causes of arc development in the Apennines, central Italy (2008)
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: In central Italy, geometry, kinematics, and tectonic evolution of the late Neogene Umbrian Arc, which is one of the main thrusts of the northern Apennines, have long been studied. Documented evidence for orogenic curvature includes vertical-axis rotations along both limbs of the arc and a positive orocline test along the entire arc. The curvature’s cause is, however, still unexplained. In this work, we focused our attention on the southern portion of the Umbrian Arc, the so-called Olevano-Antrodoco thrust. We analyze, in particular, gravity and seismic reflection data and consider available paleomagnetic, stratigraphic, structural, and topographic evidence from the central Apennines to infer spatial extent, attitude, and surface effects of a mid-crustal anticlinorium imaged in the CROP-11 deep seismic profile. The anticlinorium has horizontal dimensions of about 50 by 30 km and is located right beneath the Olevano-Antrodoco thrust. Stratigraphic, structural, and topographic evidence suggests that the anticlinorium produced a surface uplift during its growth in early Pliocene times. We propose an evolutionary model in which, during late Neogene time, the Olevano-Antrodoco thrust developed in an out-of-sequence fashion and underwent about 16° of clockwise rotation when the thrust ran into and was then raised and folded by the growing anticlinorium (late Messinian-early Pliocene time). This new model suggests a causal link between mid-crustal folding and surficial orogenic curvature that is consistent with several available data sets from the northern-central Apennines; more evidence is, however, needed to fully test hypothesis. Additionally, due to the occurrence of mid-crustal basement-involved thrusts in other orogens, this model may be a viable mechanism for arc formation elsewhere.

    Is large scale subduction made unlikely by the mediterranean deep seismicity? (2008)
    NCGT (New Concept in Global Tectonics) Group
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: In the conclusions the paper contains an hypothesis about a possible relation among the Earth's oceans half spreading rate, the global expansion of the planet and the uplift of the thrust-fold belts.
    Beschreibung: The deep seismicity in the Mediterranean region does not have the pattern that the alleged convergence of Africa and Eurasia should produce. Often, where subduction slabs and Wadati-Benioff zones should be present – showing intermediate and deep hypocenters – only shallow intracrustal seismicity is detected. Most geoscientists admit, without a valid explanation, that in this region subduction occurs largely aseismically. Inspection of South Tyrrhenian, Aegean and South Carpathian deep foci zones makes clear that these isolated narrow plumes (or clusters, filaments) of hypocentres cannot be sites of active subduction but that they are related to uplift of deep mantle material. Their presence under actively rising part of orogens – besides many additional clues coming from a number of different fields –leads to a unified interpretation of the involved phenomena, and to a new interpretation of the orogenic processes and fold belt building. The evidence points to vertical displacements of materials as the main process responsible for deep earthquakes, volcanic phenomena and orogenesis. Several tens of km of overthrusts and underthrusts should not be mistaken for large-scale subduction, and the limit of 50-70 km (the roots of an orogen) should be considered the maximum depth of occurrence of metamorphism. Into these limits of depth, the nonlithostatic overpressures due to the surfaceward mantle flow, the association of fluids, extreme magnitude earthquakes and deviatoric stress can be the causes both of those metamorphosed facies (until now presumed to come from depth up to 200 km) and of a shallower than supposed synthesis of biogenic and abiogenic hydrocarbons.

    Meno misteri nelle viscere del vulcano (2008)

    Beschreibung: La frontiera della ricerca della geofisica moderna si fonda in maniera rilevante su due direttrici al crocevia tra scienza e tecnologia: il progresso tecnologico nella strumentazione per le misure e l'affinamento della capacità di gestione ed elaborazione delle informazioni raccolte. Come in ogni altra scienza sperimentale, i dati e la capacità di saperli analizzare rappresentano pilastri fondamentali nella ricerca geofisica. Allo stato attuale l'Europa è messa a confronto con l'impressionante sviluppo che sta avvenendo in Paesi quali Giappone e Usa. Un esempio significativo è rappresentato dalla campagna di misure sull'isola di Tenerife, alle Canarie, a opera dell'Istituto Nazionale di Geofisica e Vulcanologia presieduto da Enzo Boschi e il Consejo Superior de Investigaciones Cientificas spagnolo. Il grande vulcano Teide, che domina l'isola e che è giudicato dagli esperti "ad alto rischio", è stato investigato con una tecnica di rilevamento innovativa, chiamata aeromagnetismo. Per svelare i segreti dell'edificio vulcanico sottomarino, fin dentro la crosta terrestre, gli scienziati hanno operato dal cielo, a bordo di un elicottero attrezzato con apparati di alta tecnologia sospesi in una sorta di missile che al suo interno ospita i sensori che captano i campi magnetici delle rocce vulcaniche. I rilievi aeromagnetici effettuati consentiranno di identificare le strutture sepolte, in modo tale da ricostruire formazioni come condotti lavici, crateri e faglie. Un contributo (non solo a beneficio della geofisica ma anche della Protezione Civile spagnola) che è stato realizzato con una tecnologia avanzata, fiore all'occhiello dell'Italia e dell'Istituto Nazionale di Geofisica e Vulcanologia. Si tratta inoltre di un esempio estremamente interessante, di cooperazione tra istituzioni italiane ed europee che risulta affiancato da un protocollo ministeriale tra Italia, Spagna e Portogallo realizzato nel 2005 con il sostegno della Fondazione Cotec. La fisica dei terremoti e dei fenomeni vulcanici non soltanto non rispetta le frontiere nazionali coinvolgendo spesso Paesi limitrofi ma (si pensi ai grandi mercati primari e secondari di assicurazione) ne coinvolge in maniera tanto pervasiva le economie da richiedere risposte di impegno e coordinamento di statura europea.

    The Tortonian salinity crisis in the Fortuna Basin (southeastern Spain): Stratigraphic record, tectonic scenario and chronostratigraphy (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The Neogene Fortuna and Bajo Segura basins are located on the northeastern end of the Trans-Alborán Shear Zone (TASZ), on the eastern Betic cordillera. The stratigraphic study of the infilling of these basins has shown two major sedimentary discontinuities. The first one, represented by an erosive surface separating open marine marls from an overlying coastal conglomeratic unit, is linked to the onset of the activity along the TASZ, which in this area indicates the beginning of the Abanilla Thrust emplacement. In the Fortuna Basin, the Tortonian salinity crisis, registered over this older first discontinuity, was therefore related to tectonic processes of the eastern portion of the cordillera and consequently would not have an expression in the western basins. The age of the Tortonian Salinity Crisis has been established with nannofossil biostratigraphy as Latest Tortonian at a somewhat lower stratigraphic position than previously recognized. The second sedimentary discontinuity was developed in relation with the known Mediterranean-wide Messinian salinity crisis.

    Vertical-axis rotation of a foreland fold and implications for orogenic curvature: an example from the Southern Pyrenees, Spain (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: In curved orogenic systems where thrusting and vertical-axis rotations have been documented, it is possible to determine whether the curvature is secondary or progressive based on the timing between the two motions. The South-Central Unit of the Southern Pyrenees provides an opportunity to investigate relationships between thrusting, folding, and vertical-axis rotation because of unusual preservation of Tertiary synorogenic sedimentary strata. Paleomagnetic samples were collected from 51 sites in the upper Eocene-lower Oligocene continental synorogenic strata of the Oliana anticline, a foreland fold along the eastern margin of the South-Central Unit. Site-mean characteristic remanent magnetization directions were determined from 17 sites through thermal demagnetization and principal component analysis. In addition, 72 samples were collected from 39 stratigraphic levels spanning the Upper Eocene marine marls and treated with thermal and alternating field demagnetization techniques. Of these, 53 samples yielded demagnetization trajectories that further constrained the rotation. Comparison of the observed mean paleomagnetic direction from the Oliana anticline with the expected direction indicates a counterclockwise rotation (R ± ΔR) of 20.3° ± 10.9°. Based on the stratigraphic horizons recording the rotation, the age of the rotation is younger than ~34 Ma (after deposition of Unit 3). Data covering the Upper Eocene-Lower Oligocene time interval indicate a similar magnitude of rotation, suggesting that late stage emplacement of thrust sheets hinterlandward of the Oliana anticline controlled the rotation, with rotation accommodated along regionally extensive evaporites. The well-constrained timing relationships between thrusting and rotation and the regional and local transport directions, suggest that the South-Central Unit is a progressive curve that formed through distributed shortening.

    Paleo-environmental and volcano-tectonic evolution of the southeastern £ank of Mt. Etna during the last 225 ka inferred from the volcanic succession of the ‘Timpe’, Acireale, Sicily (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The tectonic escarpments locally known as ‘Timpe’ cut a large sector of the eastern flank of Etna, and allow an ancient volcanic succession dating back to 225 ka to be exposed. Geological and volcanological investigations carried out on this succession have allowed us to recognize relevant angular unconformities and volcanic features which are the remnants of eruptive fissures, as well as important changes in the nature, composition and magmatic affinity of the exposed volcanics. In particular, the recognition in the lower part of the succession of important and unequivocal evidence of ancient eruptive fissures led us to propose a local origin for these volcanics and to revise previous interpretations which attributed their westward-dipping to the progressive tectonic tilting of strata. These elements led us to reinterpret the main features of the volcanic activity occurring since 250 ka BP and their relationship with tectonic structures active in the eastern flank of Etna. We propose a complex paleo-environmental and volcanotectonic evolution of the southeastern flank of Mt. Etna, in which the Timpe fault system played the role of the crustal structure that allowed the rise and eruption of magmas in the above considered time span.

    Link between major flank slip and 2002–2003 eruption at Mt. Etna (Italy) (2008)
    American Geophysical Union
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The 2002–2003 Etna eruption is studied through earthquake distributions and surface fracturing. In September 2002, earthquake-induced surface rupture (sinistral offset 0.48 m) occurred along the E-W striking Pernicana Fault (PF), on the NE flank. In late October, a flank eruption accompanied further ( 0.77 m) surface rupturing, reaching a total sinistral offset of 1.25 m; the deformation then propagated for 18 km eastwards to the coastline (sinistral offset 0.03 m) and southwards, along the NW-SE striking Timpe (dextral offset 0.04 m) and, later, Trecastagni faults (dextral offset 0.035 m). Seismicity (〈4 km bsl) on the E flank accompanied surface fracturing: fault plane solutions indicate an overall ESEWNWextension direction, consistent with ESE slip of the E flank also revealed by ground fractures. A three-stage model of flank slip is proposed: inception (September earthquake), climax (accelerated slip and eruption) and propagation (E and S migration of the deformation).

    The Database of Individual Seismogenic Sources (DISS), version 3: summarizing 20 years of research on Italy’s earthquake geology (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: This paper describes the main characteristics, the evolution, and the structure of the Database of Individual Seismogenic Sources (DISS) and particularly of its release of early 2007. The Database contains the results of the investigations of the active tectonics in Italy during the past 20 years. The first two sections of this paper document the recent evolution in mapping and archiving Italian active fault data in relation to important achievements in the understanding of Italian tectonics, some of which were spurred by significant earthquakes. The central sections describe the current structure of the Database, the reasons for its assumptions and data categories, its current contents, its evolution through several years of improvements. The last section describes how the current contents of the Database correspond with the existing strain and stress data available from focal mechanism, borehole breakout, and GPS data for the whole of Italy. The Database supplies a fresh and unified view of active and seismogenic processes in Italy by building on basic physical constraints concerning rates of crustal deformation, on the continuity of deformation belts and on the spatial relationships between adjacent faults, both at the surface and at depth.

    Miocene-Quaternary structural evolution of the Uyuni-Atacama region, Andes of Chile and Bolivia (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: We describe the Miocene-Quaternary geological-structural evolution of the region between the Salar de Uyuni and de Atacama, Andes of Chile and Bolivia. We recognised four main tectonic events based on fold geometry, fault kinematics and stratigraphic data. The oldest event, of Miocene age, is characterized by folding and reverse faulting of the sedimentary successions with an E-W direction of shortening in the northern part of the studied area and a WNW-ESE shortening in the southern part. The following two events, of Pliocene age, are characterized by lower shortening amounts; they occurred first by reverse faulting with a NW-SE-trending greatest principal stress (1, computed with striated fault planes) and a vertical least principal stress (3), followed by pervasive strike-slip faulting with the same NW-SE-trending 1 and a horizontal NE-SW 3. The fourth event, dating to the late Pliocene-Quaternary is characterised by normal faulting: the 3 still trends NE-SW, whereas the intermediate principal stress 2 exchanged with 1. Volcanism accompanied both the contractional, transcurrent and extensional tectonic phases. The Mio-Pliocene compression appears directly linked to a rapid convergence and an apparently important coupling between the continental and oceanic plates. The E-W to WNW-ESE direction of shortening of the Miocene structures and the NW-SE 1 of the Pliocene structures seem to be more linked to an intra-Andean re-orientation of structures following the WNW-directed absolute motion of the South-American Plate. The extensional deformations can be interpreted as related to gravity forces affecting the highest parts of the volcanic belt in a sort of asymmetrical (SW-ward) collapse of the belt.

    Seismic strain and seismogenic stress regimes in the crust of the southern Tyrrhenian region (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: An investigation has been performed to identify and characterize the seismic deformation zones active over the last decades in the region of Italy that has experienced the strongest seismicity during the last centuries. The study is based on the estimate of hypocenter locations, fault plane solutions, seismogenic stress and seismic strain tensor orientations carried out using the entire dataset of the national and local seismic networks, and the recently improved three-dimensional (3D) crustal velocity model of the study area. A series of simulation tests have been performed to evaluate the significance of the earthquake space distribution obtained and whether it was influenced by network geometry problems related to the sea and the lack of ocean bottom seismometers. In the sectors where hypocentral location was synthetically proved to be reliable, space distributions of earthquakes located with epicenter and focal depth errors less than 3 and 4 km, respectively, have been compared with local geology in order to identify seismogenic faults. The dataset of 32 fault plane solutions estimated with fault parameter errors less than 20° has been used to investigate space variations of seismogenic stress and seismic strain orientations over the study area. Stress was found to be uniform in the Messina Strait and southern Calabria where inversion of the available set of 11 fault plane solutions showed clear evidence of an extensional regime. The different orientations of the minimum compressive stress and strain found in this sector, together with the information available on local geology and tectonics, lead us to propose that the seismicity occurring over the last decades in the Messina Strait and southern Calabria was not in general produced at the main faults, but at minor faults activated by the main tectonic stress field acting in the area. To the west, in the sector including western Etna, the Nebrodi chain and the western Aeolian Islands, analysis of the available set of 16 fault plane solutions revealed a certain degree of stress heterogeneity with an apparent prevalence of north–south compression. This east to west change of stress–strain regimes is evaluated in the light of current hypotheses regarding the geodynamics of the study region.

    La definizione delle geometrie sedimentarie sepolte attraverso l’interpretazione integrata di dati geologici, geomorfologici e geofisici nella piana di Bojano (Provincia di Campobasso) (2008)
    Società Geologica Italiana
    Details
    Publikationsdatum: 2019-12-18
    Beschreibung: The Bojano plain corresponds to an elongated basin with Apennine direction, delimited by the Matese massif to SW and by the Sannio hills to NE. This area was studied utilizing geologic, geomorphologic and geophysical data, acquired mainly for microzoning of the Bojano town. Seismic reflection data reveal structural depressions nearby the centre of the town and two basins filled by recent fluvial-lacustrine deposits at the NW and SE sectors of the plain, respectively. Low angle tectonic structures correlate with the thrust of the Matese chain over the frontal more deformable sequences of the Sannio units, but any high angle active structure cutting the Matese thrusts at their eastern limit and in the first 1500 m has been imaged. The seismic sections have been complemented by H/V measurements of the seismic noise utilizing a seismological network installed for sites amplification analysis with a reference station and by an accurate study of the geomorphology of the area. Analyses of the morphogenetic processes contribute to the description of the evolution of the plain and of the depocentres, with depressions and structural highs or divides which strongly influenced the rivers action and the arrival of the alluvial cones.

    Insights from scaled analogue modelling into the seismotectonics of the Iranian region (2008)
    Details
    Publikationsdatum: 2020-05-28
    Beschreibung: We show how analogue modelling provides insights into complex crustal block kinematics and the seismotectonics of active areas undergoing contraction, such as the Iranian region. The seismotectonic model deriving from this analysis is consistent with partitioning of the N-directed Arabia indentation into a composite system of collision-oblique and collision-parallel seismogenetic belts. These features include (1) two main conjugate transpressive belts (the dextral NW – SE-trending Zagros belt and the NE – SW-trending sinistral Elburz-Aran-Torud (EAT) belt), and (2) a modest lateral escape of Central Iran towards the Lut block along the Nayband belt. This cinematic model fits the seismic activity and the current fault pattern of the region. Also, the velocity field scaled from the model to nature shows a good similarity with previous numerical modelling as well as with deformation rates along the first-order seismogenetic belts determined by plate tectonic models and GPS data.

    Tectonic modeling of Konya-Beysehir Region (Turkey) using cellular neural networks (2008)
    Details
    Publikationsdatum: 2019-11-04
    Beschreibung: In this paper, to separate regional-residual anomaly maps and to detect borders of buried geological bodies, we applied the Cellular Neural Network (CNN) approach to gravity and magnetic anomaly maps. CNN is a stochastic image processing technique, based optimization of templates, which imply relationships of neighborhood pixels in 2-Dimensional (2D) potential anomalies. Here, CNN performance in geophysics, tested by various synthetic examples and the results are compared to classical methods such as boundary analysis and second vertical derivatives. After we obtained satisfactory results in synthetic models, we applied CNN to Bouguer anomaly map of Konya-Beysehir Region, which has complex tectonic structure with various fault combinations. We evaluated CNN outputs and 2D/3D models, which are constructed using forward and inversion methods. Then we presented a new tectonic structure of Konya-Beysehir Region. We have denoted (F1, F2, …, F7) and (Konya1, Konya2) faults according to our evaluations of CNN outputs. Thus, we have concluded that CNN is a compromising stochastic image processing technique in geophysics.

    Timing and magnitude of rotations in the frontal thrust systems of southwestern Sicily (2008)
    AGU
    Details
    Publikationsdatum: 2021-09-08
    Beschreibung: We report new paleomagnetic and anisotropy of magnetic susceptibility (AMS) results from upper Tortonian to middle Pleistocene sediments which were deposited upon and adjacent to active thrust structures in southwestern Sicily. The data show that the Plio-Pleistocene sediments from the Belice and Menfi basins (covering the Saccense shelf limestones) underwent any internal shortening after the early Pleistocene (Santernian), as well as any net rotation. Sediments around this area (which overlie basinal Meso-Cenozoic successions) record systematic rotations: one upper Tortonian site to the west is ~30° counterclockwise rotated, while to the east, lower Pliocene to middle lower Pleistocene sites within the Gela Nappe domain show 25° to 56° clockwise (CW) rotations. These data show that the ductile basinal sediments were bent and rotated around the rigid Saccense carbonates during the thin-skinned southward propagation of the orogenic front. We document here that the coastal sediments from the southwestern Gela Nappe underwent both a post middle early Pleistocene ~30° CW rotation and a post middle Pleistocene E-W to ESE-WNW flattening (revealed by AMS). Our data then constrain to the late Pleistocene-Holocene the age of the last shortening episode occurring in the southwestern Gela Nappe front. Pleistocene rotations of similar amount also characterize the Sicanian domain, implying that it was incorporated in the Gela Nappe wedge during the recentmost episodes of deformation. This evidence allows us to better understand the very large (up to 114°) post Mesozoic rotations reported by Channell et al. [1980, 1990] for the Sicanian limestones, as related to both Miocene (or older?) deformational episodes and the Plio-Pleistocene evolution of the Gela Nappe.

    Analisi del campo di deformazione superficiale della Regione Campania da dati SAR (PS-InSAR) (2008)
    Details
    Publikationsdatum: 2021-11-09
    Beschreibung: Il lavoro presenta un’applicazione della tecnica dei diffusori permanenti (Permanent Scatterers) finalizzata alla caratterizzazione del campo di deformazione superficiale della Regione Campania. Per effettuare l’analisi sono state processate, tramite la tecnica PS-InSARTM, 1078 scene SAR ERS1 ed ERS2 relative al periodo giugno 1992 - gennaio 2001. Sulla base della velocità media annua di spostamento di 1.691.740 PS con coerenza maggiore di 0.65 sono state prodotte mappe di velocità media di deformazione mediante l’utilizzo di una procedura articolata nei seguenti punti: a) filtraggio dei dati effettuato sulla base dei valori di coerenza; b) produzione di mappe di velocità media di deformazione in coordinate SAR; c) generazione di mappe di velocità media di deformazione secondo le componenti verticale ed Est-Ovest; d) validazione di risultati mediante confronto con dati prodotti con differenti metodiche d’indagine. L’analisi dei risultati ottenuti ha consentito di identificare aree caratterizzate da distinti stili deformativi. Aree in subsidenza sono risultate essere, per il periodo di interesse, oltre all’area vulcanica dei Campi Flegrei, le aree costiere dei bacini dei fiumi Volturno e Sele ed il settore centrale dell’isola d’Ischia. Aree con significativi valori di sollevamento sono localizzate nel settore settentrionale del Monte Somma, nel settore centrale della Piana Campana, nel Sannio e nel Cilento. Significativi valori di velocità di spostamento in direzione EW si riscontrano, oltre che nell’area dei Campi Flegrei, nel settore appenninico del bacino del Sele e nell’area interposta tra il Somma-Vesuvio e la catena appenninica. Il quadro deformativo globale risulta essere caratterizzato da un andamento complesso, governato da una molteplicità di processi di differente natura (tettonici, vulcano-tettonici, esogeni ed antropici).

    Neogene–Quaternary evolution of the central Apennine orogenic system (Italy): a structural and palaeomagnetic approach in the Molise region (2008)
    Elsevier
    Details
    Publikationsdatum: 2022-05-30
    Beschreibung: We report on new palaeomagnetic and magnetic fabric analyses of mainly Upper Miocene sedimentary sequences from the external central Apennine fold and thrust belt (Molise area), where the principal compressive structures are clearly non-coaxial. The sampling was carried out on the E–W-oriented Matese–Frosolone thrust sheet, that for its geographical position and structural setting (superposition of thrusting, strike-slip and extensional tectonics since Late Miocene to present-day) represents a key structure for the comprehension of the Neogene–Quaternary evolution of the entire Molise area. Palaeomagnetic results suggest that the Matese–Frosolone thrust sheet counterclockwise rotated at least 35° after Messinian times. These data confirm that the present-day trend variability observed in the main compressional structures in the Apennine chain can be related to rotations about vertical axes rather than to changes in the stress field orientation, at least since Late Miocene times. Magnetic fabric analyses indicate that the studied sediments were subjected to very mild deformation, suggesting that the surface emergence of the thrust front of the Matese–Frosolone unit is located farther north, far from the studied area. Well-defined magnetic lineations of tectonic origin were only observed in sites close to localised belts of strike-slip deformation.

    Active tectonics and seismic zonation of the urban area of Florence. (2008)
    Details
    Publikationsdatum: 2022-08-25
    Beschreibung: The city of Florence possesses a concentration of cultural and artistic treasures which is unique in the world. In this sense it has a particularly high seismic exposure and a potentially high vulnerability. In order to better evaluate its seismic hazard and risk, we analyzed the seismic response of the urban area of Florence by performing a multidisciplinary study on the effects of earthquakes on the city. By a computer aided methodology we re-evaluated the seismic intensity reports of the May 18 and June 6, 1895 earthquakes in different parts of the city and compared these data with recent studies on surface geology, active tectonics and actual fault movements in the Florence basin. We concluded that more detailed studies of soil response are needed to form a basis for public policy.

    Late Pliocene-Quaternary evolution of outermost hinterland basins of the Northern Apennines (Italy), and their relevance to active tectonics (2008)
    Elsevier
    Details
    Publikationsdatum: 2022-08-25
    Beschreibung: We examine the tectonic evolution and structural characteristics of the Quaternary intermontane Mugello, Casentino, and Sansepolcro basins, in the Northern Apennines fold-andthrust belt. These basins have been classically interpreted to have developed under an extensional regime, and to mark the extension-compression transition. The results of our study have instead allowed framing the formation of these basins into a compressive setting tied to the activity of backthrust faults at their northeastern margin. Syndepositional activity of these structures is manifested by consistent architecture of sediments and outcrop-scale deformation. After this phase, the Mugello and Sansepolcro basins experienced a phase of normal faulting extending from the middle Pleistocene until Present. Basin evolution can be thus basically framed into a two-phase history, with extensional tectonics superposed onto compressional structures. Analysis of morphologic features has revealed the occurrence of fresh fault scarps and interaction of faulting with drainage systems, which have been interpreted as evidence for potential ongoing activity of normal faults. Extensional tectonics is also manifested by recent seismicity, and likely caused the strong historical earthquakes affecting the Mugello and Sansepolcro basins. Qualitative comparison of surface information with depth-converted seismic data suggests the basins to represent discrete subsiding areas within the seismic belt extending along the axial zone of the Apennines. The inferred chronology of deformation and the timing of activity of normal faults have an obvious impact on the elaboration of seismic hazard models.

    The 1755 “Meknes” earthquake (Morocco): field data and geodynamic implications. (2008)
    Details
    Publikationsdatum: 2022-08-25
    Beschreibung: The source of the famous 1 November, 1755 ‘‘Lisbon’’ earthquake has been constrained to be an up to 200 km long structure in the offshore west of Cabo de S. Vincente.The magnitude of this earthquake was estimated in the range of 8.5–9.4. The stress regime argued for this shock would have been characterised by an around NNW–SSE-oriented compression.Less well studied is the successive ‘‘Meknes’’ earthquake, which occurred a few days later in Morocco (27 November), and was erroneously confused by the European contemporary reports with a strong aftershock, occurred on 18 November, of the main seismic sequence of the 1 November earthquake.The Meknes earthquake had destructive effects in the region of Meknes and Fes and along the E–W trending Rides Pre´rifaines, the main frontal thrust of the Rif.Historical data indicate a macroseismic field closed around the towns of Meknes and Fes. Our structural–geological fieldwork and remote sensing analysis in the epicentral area of the Meknes earthquake, along the local major recent faults, indicate that the E–W-oriented thrusts of the Rides Pre´- rifaines are active.Throu gh a re-examination of historical sources compared with field work and air photo interpretation, we could individuate the traces of coseismic surface faulting of the 1755 Meknes earthquake in two areas of the Rides Pre´rifaines, both part of the local thrust front: the Jebel Zerhoun area and the Jebel Zalagh area.Tectonic data on the Quaternary stress fields derived from our fieldwork and from literature, consistently with the revised focal mechanisms in the region, indicate active shortening oriented NNW–SSE to N–S in northern Morocco.The data collected seem therefore to indicate the thrusts of the Rides Pre´rifaines, located within the macroseismic area of the Meknes earthquake, as the most probable seismic source of that event.As such, the activation of the thrusts of the Rides Pre´rifaines would be consistent with this stress regime, which in turn would be similar to the stress field maintained as responsible for the 1 November, 1755 Lisbon earthquake.W e also attempted an estimate of the change due to the Lisbon earthquake of the Coulomb Failure Function (CFF) on the Meknes structure, as identified in this paper, in order to evaluate if the Meknes earthquake could have been induced by the 1 November, 1755 Lisbon earthquake, or a local distinct earthquake.Our modelling suggests that the latter hypothesis is the more likely one.

    Magnetotelluric investigation in a seismogenic source area: Evidences from the 1930 Irpinia earthquake area (2008)
    Details
    Publikationsdatum: 2023-06-12
    Beschreibung: On 23 July 1930, the Irpinia region in southern Italy experienced a destructive (M 6.7) earthquake that struck the eastern sector of the southern Apennines moutain belt. Previous studies suggest that this earthquake was caused by a seismogenic source having oblique right-lateral kinematics and striking at an angle between the general trend of NE-verging large dip-slip faults in the southern Apennines (~ NW-SE) and the E-W near-vertical, strike-slip right lateral faults that have been recently discovered in the foreland, east of the main extensional axis. Also, the ~14 km hypocentral depth of the 1930 earthquake that has been calculated in previous studies is likely located within the basement below the Apula carbonate platform succession. This puts the source of the 1930 earthquake not only in an intermediate region between pure normal (NW-SE) and strike-slip right-lateral (E-W) large seismogenic faults in the southern Apennines, but also at an hypocentral depth between the 12-13 km depth of the earthquakes caused by normal faulting (like the Irpinia 23 Nov. 1980, M 6.9 one) and the 15-20 km depth of the earthquakes caused by strike-slip faulting in the foreland (like the 31 Oct.-1 Nov. 2002, M 5.8 Molise ones). In this framework, we performed a magnetotelluric (MT) study to investigate the evidence of preferential direction in resistivity anisotropy and to compare it with the strike of the 1930 seismogenic fault.

    Publikationsdatum: 2024-01-12
    Beschreibung: This paper aims to fill some gaps in the taxonomic knowledge of the genus Ptomaphaginus for the Sunda region (in insular and peninsular Southeast Asia). We have refrained from a full regional revision. However, we present new distribution records for the following previously described species: Ptomaphaginus murphyi Szymczakowski, 1970 (Malaysia); P. rufus Jeannel, 1936 (Malaysia); P. tarsalis Szymczakowski, 1964 (Sumatra); P. aff. scaphaner Szymczakowski, 1972 (Malaysia, Java); P. sinuatus Schilthuizen, 1984 (Java); P. baliensis Perreau, 1995 (Sumatra). We also name 12 new species: P. anas spec. nov. (Malaysia); P. bryantioides spec. nov. (Borneo); P. caroli spec. nov. (Borneo), P. similipes spec. nov. (Borneo); P. kinabaluensis spec. nov. (Borneo); P. latimanus spec. nov. (Borneo); P. burckhardti spec. nov. (Borneo); P. giachinoi spec. nov. (Sumatra); P. agostii spec. nov. (Java); P. kurbatovi spec. nov. (Java); P. loeblianus spec. nov. (Sumatra). P. sabahensis spec. nov. (Borneo), and one new synonym (P. balazuci Perreau, 1995 syn. nov. for P. obtusus Szymczakowski 1959). Finally, we highlight a group of species with a characteristically shaped aedeagus, which are targeted for further phylogenetic and evolutionary study. In view of the 250th anniversary of zoological nomenclature, we name one species in honour of Carolus Linnaeus.

    Surimyia, a new genus of Microdontinae, with notes on Paragodon Thompson, 1969 (Diptera, Syrphidae) (2008)
    In:  Zoologische Mededelingen vol. 82 no. 18, pp. 177-188
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Surimyia, a new genus of Microdontinae (Diptera: Syrphidae) is described, based on specimens from Suriname. Surimyia is the only known genus of Syrphidae in which the katatergum (ventral part of lateral postnotal sclerite of mesonotum) lacks microtrichia. Within Microdontinae, the genus is unique in the absence of pilosity on the postpronotum. It is also remarkable in the presence of strong, black setae on thorax and abdomen, a character rarely found in Syrphidae. The genus is superficially similar in external morphology and colouration to Paragodon Thompson, 1969, but clearly different in the characters mentioned above, as well as in the structure of the male genitalia. Two species are assigned to Surimyia: S. minutula (van Doesburg, 1966) and S. rolanderi spec. nov. Generic morphology is discussed. Differences between the species are described and illustrated.

    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Recent collections of bird\xe2\x80\x99s nest fungi (i.e. Crucibulum, Cyathus, Mycocalia, Nidula, and Nidularia species) in northern Thailand resulted in the discovery of a new species of Cyathus, herein described as C. subglobisporus.\nThis species is distinct by a combination of ivory-coloured fruiting bodies covered with shaggy hairs, plications on the inner surface of the peridium and subglobose basidiospores. Phylogenetic analyses based on ITS and\nLSU\nribosomal DNA sequences using neighbour-joining, maximum likelihood and weighted maximum parsimony support Cyathus subglobisporus as a distinct species and sister to a clade containing C. annulatus, C. renweii and C. stercoreus in the Striatum group.

    Tetractinellid and hadromerid sponges of the Sultanate of Oman (2008)
    In:  Zoologische Mededelingen vol. 82 no. 53, pp. 749-790
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: The Sultanate of Oman harbours rich populations of sponges, especially in the four coral reef areas (Musandam Peninsula, Muscat coast & Daymaniyat islands, coasts of Masirah Island, and the Khuriya Muriya Islands). Up till now, apart from a few incidental samples, the sponges of Oman were known only from five dredge stations made by the John Murray Expedition 1933-1934 off the south coasts of Oman, near the Khuriya Muriya Islands, between 13.5 and 1415 m. Descriptions of the sponges obtained in these dredges were published by Burton (1959) and the specimens are deposited in the collections of the Natural History Museum, London. To complement these dredge samples, we recently obtained samples collected by SCUBA and shore collecting, mostly from the northern part of Oman, deposited in the collections of the Zoological Museum of the University of Amsterdam. We studied the combined Oman collections of the Amsterdam and London Museums. In the present contribution we treat the species belonging to the tetractinellid and hadromerid Demospongiae. The sponges of the Zoological Museum of Amsterdam are fully described and illustrated, those of the John Murray Expedition are annotated and illustrated here with habit photographs, as these were entirely lacking from Burton\xe2\x80\x99s (1959) report. The collection studied here contains 30 species, two of which are new to science, six are up till now known only from Oman waters, while the remaining 24 species are shared with other areas. The Indian subcontinent shares the most species with Oman, followed by East African areas, while the nearby Arabian coasts share only few species, probably due to the poor knowledge of sponges from this region.
