    Ups and downs in western Crete (Hellenic subduction zone) (2014)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: Studies of past sea-level markers are commonly used to unveil the tectonic history and seismic behavior of subduction zones. We present new evidence on vertical motions of the Hellenic subduction zone as resulting from a suite of Late Pleistocene - Holocene shorelines in western Crete (Greece). Shoreline ages obtained by AMS radiocarbon dating of seashells, together with the reappraisal of shoreline ages from previous works, testify a long-term uplift rate of 2.5-2.7 mm/y. This average value, however, includes periods in which the vertical motions vary significantly: 2.6-3.2 mm/y subsidence rate from 42 ka to 23 ka, followed by ~7.7 mm/y sustained uplift rate from 23 ka to present. The last ~5 ky shows a relatively slower uplift rate of 3.0-3.3 mm/y, yet slightly higher than the long-term average. A preliminary tectonic model attempts at explaining these up and down motions by across-strike partitioning of fault activity in the subduction zone.

    Lava flow hazards at Mount Etna: constraints imposed by eruptive history and numerical simulations (2014)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: Improving lava flow hazard assessment is one of the most important and challenging fields of volcanology, and has an immediate and practical impact on society. Here, we present a methodology for the quantitative assessment of lava flow hazards based on a combination of field data, numerical simulations and probability analyses. With the extensive data available on historic eruptions of Mt. Etna, going back over 2000 years, it has been possible to construct two hazard maps, one for flank and the other for summit eruptions, allowing a quantitative analysis of the most likely future courses of lava flows. The effective use of hazard maps of Etna may help in minimizing the damage from volcanic eruptions through correct land use in densely urbanized area with a population of almost one million people. Although this study was conducted on Mt. Etna, the approach used is designed to be applicable to other volcanic areas.
    Description: This work was developed within the framework of TecnoLab, the Laboratory for Technological Advance in Volcano Geophysics organized by INGV-CT, DIEES-UNICT, and DMI-UNICT.

    Active deformation along the northern margin of the Hyblean Plateau (SE Sicily) from GPS and geological data (2013)
    Società Geologica Italiana
    Details
    Publication Date: 2021-09-08
    Description: A diffuse fragmentation of the Nubia-Eurasia tectonic boundary, due to the propagation of distinct extensional belts, has characterised the post-collision evolution of the region. In this frame, the Hyblean Plateau was affected, since about 1.5 Ma B.P., by the propagation of the the roughly N-S trending Siculo-Calabrian Rift Zone (SCRZ in Fig.1a; MONACO & TORTORICI, 2000), an extensional belt that extends from the onshore of southern Calabria to the SE Sicily. In the Hyblean plateau the propagation of the rift zone caused the reactivation of the main previous discontinuity. The earlier SE Sicily branch of the rift zone, in fact, propagated from the Ionian coast to the Scicli Line, causing the collapse of the NEtrending Scordia-Lentini Graben, at the northern margin of the plateau. This extensional basin represents an half-graben, which is controlled by a SE-facing master fault.

    Geological evolution of a complex basaltic stratovolcano: (2012)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: An updated geological evolution model is presented for the composite basaltic stratovolcano of Mount Etna. It was developed on the basis of the stratigraphic setting proposed in the new geological map that was constrained by 40Ar/39Ar age determinations. Unconformitybounded stratigraphy allows highlighting four main evolutionary phases of eruptive activity in the Etna region. The Basal Tholeiitic Supersynthem corresponds to a period, from about 500 to 330 ka, of scattered fissure-type eruptions occurring initially in the foredeep basin and then in a subaerial environment. From about 220 ka, an increase in the eruptive activity built a lava-shield during the Timpe Supersynthem. The central-type activity occurred at least 110 ka ago through the Valle del Bove Supersynthem. The earliest volcanic centres recognized are Tarderia, Rocche and Trifoglietto and later Monte Cerasa, Giannicola, Salifizio and Cuvigghiuni. During the Stratovolcano Supersynthem, from about 57 ka ago, the intense eruptive activity of Ellittico volcano formed a roughly 3600 m-high stratocone that expanded laterally, filling the Alcantara and Simeto paleovalleys. Finally, effusive activity of the last 15 ka built the Mongibello volcano. Its eruptive activity is mainly concentrated in three weakness zones in which the recurrent magma intrusion generates flank eruptions down to low altitude. The four main evolutionary phases may furnish constraints to future models on the origin of Etna volcano and help unravel the geodynamic puzzle of eastern Sicily.

    Geological map of Etna volcano, 1:50,000 scale (2012)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: The new geological map of Etna volcano at 1:50,000 scale represents a significant progress in the geological studies of this volcano over the last 30 years, coming after Waltershausen’s map published around the mid of 19th century, the first geological map of a large active volcano, and the ROMANO et alii (1979) map published about a century later, both at 1:50,000 scale. Lithostratigraphy was used for mapping volcanic units and then Unconformity Bounded Units were applied to group lithostratigraphic units into synthems. In addition, lithosomes were exploited to better represent the spatial localization of different eruptive centres according to their morphology. On the whole, we identified 27 lithostratigraphic units, grouped into 8 synthems, and 9 volcanoes. In detail, effusive and explosive deposits generated by each eruption of Mongibello and, partially, Ellittico volcanoes were mapped as flow rank. This stratigraphic framework represents the best synthesis of the geological evolution of Etna volcano using the main unconformities recognized within its complex volcanic succession. In addition, we constrain the Etna volcanic succession and its lithostratigraphic units chronologically by radioisotope age determinations. On the basis of the outlined synthemic units, it was possible to divide Etna’s volcanic succession into 4 supersynthems, which correspond to 4 well-defined and spatially localized phases. The detailed reconstruction of the past eruptive activity allowed compiling the most accurate dataset in particular of the Holocene eruptions of Etna volcano, which will enable significantly improving the volcanic hazard assessment, together with petrological interpretation of erupted magmas and geophysical modelling of the volcano plumbing system.

    From compression to extension during the Sicily chain building (2010)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: Kinematics of mountain belts is often very difficult to decipher. Main problems consist in the linkage between different stages of deformation which define the chain building, their significance in the context of lithospheric evolution dominate by plate collision and the interaction with previous structures recorded in the rocks. Also, the overprinting of structures developing later with respect to the chain building may further makes complicate the way to unravel the tectonic evolution of the wedge. In Sicily belt, located in the Central Mediterranean, the regional pattern and the tectonic evolution are described using structural analysis of small-scale structures in selected outcrops. The geometric differences existing between some types of structures within the belt allow to delineate the timing of deformations during chain building.

    Geodatabase e report di sismicità (2010)

    Publication Date: 2017-04-04
    Description: The laboratory of digital cartography and geographical information systems (LABGIS) of the ISTITUTO NAZIONALE di GEOFISICA e VULCANOLOGIA (INGV) in Grottaminarda (AV) has focused its activity on the organization and processing of a high number of cartographic, territorial, geological and geophysical data regarding Central and Southern Italy. This activity represents one of the purposes of CESIS Project whose aims are to realize a monitoring network of permanent stations with seismic, accelerometric and geodetic instruments and to create a Centre for Seismology and Seismic Engineering. The realization of a series of geographical database in ESRI Geodatabase data model with the software ArcGIS 9 has offered the possibility of trying out the opportunities of this technology as, for example, the organization of different types of geographical data and proceedings inside the same environment. The following step was to develop a series of applications as the SIT CESIS EARTHQUAKE REPORT. This application produces a cartographic report, which is able to give a territorial and seismological view for each earthquake of magnitude greater than 3.0 recorded in Southern Italy. The report contains information deriving from the historical and instrumental seismicity catalogues and information about the location of monitoring network stations, the seismic hazard and classification. All these data are produced by the INGV. This instrument is very important for the activity of seismic monitoring because it is able to give an immediate and complete answer, regarding to an occurred earthquake to the National Department of Civil Protection. That’s why it has been thought to extent the creation of a report to all the national territory, by increasing the database and developing a specific GIS application that can be used, in real time, in the seismic monitoring hall of the Centro Nazionale Terremoti in Rome.

    Evoluzione tettonica mesozoico-terziaria della Sicilia centrosettentrionale (2010)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: Sicily owes its complex geological structure to a switch in tectonic regime from the Mesozoic to the Tertiary. A set of tectonic units outcrops in the northern portion of the island that originated during the Tertiary at the expense of paleogeographic domains of the African Mesozoic continental margin. The pre-orogenic successions show different types of deformation (extensional and transcurrent) related to the Jurassic paleotectonic evolution of the southern Neotethys margin. The history of the tectonic inversion of the Neotethys shear zone is recorded in the Cretaceous strata. Extension occurred during late Cretaceous and may be compatible with the tensile stress field related to the Sicilide basin opening. The Neogene deformations are linked to collisional processes and are mostly represented by thrusts and folds. Since the late Miocene onwards, the formation of the Tyrrhenian basin has driven the recent tectonic evolution of Northern Sicily. Its basin formation was realised through extension, followed by transcurrent tectonics along its southern margin.

    Neotectonic uplift and tilting of crustal blocks in Northern Sicily (2010)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: La Sicilia settentrionale è caratterizzata da un’intensa attività sismica che è espressione di deformazioni attive. In questo settore dell’Isola affiora il nucleo della catena neogenica delle Magrebidi occidentali, che è sottoposto ad intenso sollevamento durante il Plio-Pleistocene. Le deformazioni più recenti sono, in gran parte, rappresentate da sistemi di faglie estensionali e trascorrenti. Il tasso di sollevamento non è uniforme, così come suggerisce la differente elevazione dei depositi di questo periodo. Essi affiorano lungo il settore costiero settentrionale e la loro quota decresce complessivamente dall’estremità nord-est a quella nord-ovest della Sicilia. Le deformazioni più recenti possono essere riconosciute sia attraverso l’analisi strutturale che tramite quella morfometrica. Lo studio integrato di queste due metodologie qui presentato è stato realizzato anche attraverso l’elaborazione informatizzata del modello di elevazione digitale della superficie topografica (DEM). I dati strutturali e morfometrici indicano che in Sicilia settentrionale vi è una stretta relazione tra l’attività delle faglie neotettoniche e le forme dei rilievi. Il loro confronto con alcune caratteristiche idrografiche, con la sismicità e con la distribuzione dei tassi di sollevamento suggerisce che la catena siciliana settentrionale risulta segmentata da sistemi di taglio radicati che perimetrano blocchi crostali. In particolare, la variazione di alcuni parametri morfometrici hanno permesso di identificare distinti settori di catena omogenei, ciascuno dei quali è soggetto a differenti tassi di sollevamento e di direzioni di basculamento.

    Messinian-Early Pliocene crustal shortening along the Tyrrhenian margin of Tuscany, Italy (2010)
    Società Geologica Italiana
    Details
    Publication Date: 2022-05-04
    Description: This paper illustrates the results of structural studies carried out in the western margin of Tuscany along a major crustal structure. Surface deformation of sediments filling different basins aligned on top of this major structure (from north to south: the Fine Basin, the Sassa–Guardistallo basin, the Rio Guardigiano area in the Lustignano basin) allow us to date its tectonic activity to the Messinian-Early Pliocene. In these areas, structures such as reverse and strike-slip faults and mesoscopic folds are widely developed. Structural analysis determined a compressive stress field with the σ1 oriented from E-W to NE-SW active from Messinian to Early Pliocene. At the southern end of this crustal structure, the Gavorrano antiform and the granitic pluton (radiometric age of granite ~4.4 Ma) coring this fold correlate with a thrust ramp anticline at depth, and thus constrain thrust activity to the Early Pliocene. These data document a Messinian–Early Pliocene compressive activity that contrasts with models invoking continuous extensional tectonics affecting the hinterland since the Late Oligocene-Middle Miocene in the frame of a back-arc-slab retreating process. The results presented therefore raise the question of which geodynamical model could account for such a complex structural evolution of Northern Apennines hinterland.
