    La sismicità del Montefeltro (Appennino settentrionale, Italia centrale) nel periodo 2005-2017 (2019)
    INGV

    Publication Date: 2019-12-16
    Description: In questo articolo viene esaminata la sismicità del Montefeltro, una regione storica dell’Appennino settentrionale, nell’Italia centrale. L’analisi si concentra sull’attività sismica avvenuta nel periodo 20052017, periodo durante il quale la Rete Sismica Nazionale (RSN) ha avuto nella regione un sostanziale miglioramento. Il data set selezionato consiste di 402 eventi per un totale di circa 7000 tempi di arrivo di fasi P e S. Gli eventi sono stati integrati con nuove letture e rilocalizzati con il programma Hypoellipse. I risultati mostrano una sismicità di fondo sporadica, sebbene piuttosto diffusa nell’area, contrassegnata da tre piccole sequenze fortemente clusterizzate nel tempo e nello spazio. Le più importanti sono avvenute nel settembreottobre 2005 (magnitudo massima ML=3.2) e nell’agostosettembre 2006 (magnitudo massima ML=3.7), rispettivamente nei dintorni dei comuni di Macerata Feltria e Casteldelci. L’evoluzione spaziotemporale di questi due episodi evidenzia un rilascio di energia tipico degli sciami sismici. Un’altra peculiare caratteristica del pattern di sismicità è rappresentata dall’occorrenza di eventi anche nella crosta inferiore e nel mantello superiore fino a profondità di almeno 50 km.

    Advances on the automatic estimation of the P-wave onset time. (2017)
    Details
    Publication Date: 2021-01-22
    Description: This work describes the automatic picking of the P-phase arrivals of the 3*10^6 seismic registers originated during the TOMO-ETNA experiment. Air-gun shots produced by the vessel “Sarmiento de Gamboa” and contemporary passive seismicity occurring in the island are recorded by a dense network of stations deployed for the experiment. In such scenario, automatic processing is needed given: (i) the enormous amount of data, (ii) the low signal-to-noise ratio of many of the available registers and, (iii) the accuracy needed for the velocity tomography resulting from the experiment. A preliminary processing is performed with the records obtained from all stations. Raw data formats from the different types of stations are unified, eliminating defective records and reducing noise through filtering in the band of interest for the phase picking. The advanced multiband picking algorithm (AMPA) is then used to process the big database obtained and determine the travel times of the seismic phases. The approach of AMPA, based on frequency multiband denoising and enhancement of expected arrivals through optimum detectors, is detailed together with its calibration and quality assessment procedure. Examples of its usage for active and passive seismic events are presented.

    Details
    Publication Date: 2018-03-23
    Description: In questo lavoro viene presentato lo stato della Rete Sismica Nazionale Italiana (RSNI) e viene analizzata la sismicità in Italia nel corso del 2012. In questo anno la RSNI risulta costituita da 413 stazioni sismiche, appartenenti all’INGV e ad altre reti locali e regionali, una parte delle quali fornisce il segnale in tempo reale al Centro Nazionale Terremoti (CNT) di Roma. Il Bollettino Sismico Italiano (BSI) del 2012 è costituito da 18221 terremoti localizzati; una parte rilevante di questa sismicità appartiene alla grande sequenza sismica emiliana che ha colpito principalmente le province di Modena, Ferrara, Reggio Emilia, Bologna, Mantova e Rovigo, causando vittime, centinaia di feriti e danni gravissimi al patrimonio artistico, all’edilizia rurale e industriale, oltre che a quella di uso civile (Fig. 1). Il 20 Maggio alle ore 02:03 UTC un terremoto di ML 5.9 (MW 5.8), preceduto alcune ore prima da uno di ML 4.1, diede inizio alla sequenza sismica. Il 29 Maggio alle ore 07:00 UTC, un altro forte terremoto (ML 5.8, MW 5.6) colpì il settore occidentale dell’area interessata dalla prima parte della sequenza sismica. Nel corso del 2012 la sequenza ha fatto registrare circa 3100 eventi sismici. Nel 2012 sono state individuate altre 27 sequenze sismiche oltre a quella emiliana. Tra di esse riveste particolare importanza quella che ha interessato la zona del Pollino, iniziata già nel 2009, e proseguita per tutto il 2012: l’evento più forte è del 25 ottobre 2012 con magnitudo ML pari a 5.0 (MW 5.2). La magnitudo minima di completezza media del BSI 2012 risulta essere MC 1.4. Il BSI 2012 contiene circa 350 eventi di origine antropica, per la massima parte esplosioni in cava, registrati in aree già note in base all’analisi della sismicità degli anni precedenti e in due nuove aree individuate. Vengono inoltre analizzate le registrazioni prodotte da una frana di crollo, fenomeno erosivo e gravitativo molto diffuso nel nostro paese, specialmente nell’arco alpino.

    Publication Date: 2017-04-04
    Description: Questo lavoro illustra lo stato della Rete Sismica Nazionale Italiana (RSNI) e le principali caratteristiche della sismicità in Italia nell’anno 2011. In tale anno, tramite i dati raccolti dalla RSNI, sono stati localizzati 16499 eventi registrati da 359 stazioni appartenenti sia all’INGV, sia ad altre reti locali e regionali connesse in tempo reale al Centro Nazionale Terremoti (CNT) di Roma. La magnitudo minima di completezza del Bollettino Sismico Italiano (BSI) è ML 1.5. La magnitudo massima è stata registrata per un evento localizzato nella pianura padano veneta (ML 4.8). Nella sismicità italiana del 2011 sono state individuate 46 sequenze sismiche rilevanti; tra esse riveste particolare interesse la sequenza nel Montefeltro: iniziata a fine maggio e durata diversi mesi, essa comprende due eventi di magnitudo ML 4.0. La sequenza del Pollino, iniziata nel 2009 e proseguita a più riprese fino al 25 ottobre 2012 con un evento di magnitudo MW 5.2, presenta a inizio 2011 un aumento della sismicità che è culminato con l’evento maggiore di quell’anno (ML 3.6). L’analisi del BSI ha inoltre permesso di individuare una nuova area caratterizzata da eventi di origine antropica (esplosioni in cava) che si aggiunge alle 16 già rilevate negli anni precedenti. In questo lavoro vengono analizzati anche i segnali prodotti da frane di crollo, molto diffuse nel nostro paese lungo gli archi montani alpini e appenninici.

    Seismic parameters re-determined from historical seismograms of 1935-Erdek–Marmara Island and 1963-Çınarcık Earthquakes (2016)
    Details
    Publication Date: 2022-06-09
    Description: In this study, the original seismograms of the 1935-Erdek–Marmara Island and 1963-Çınarcık Earthquakes, recorded at local and regional distances, were vectorized. The epicentral locations have been calculated using available readings from original records and also ISS and seismic station bulletins for 04.01.1935-14:41 and 16:20 Marmara Island–Erdek Earthquakes and 18.09.1963-16:58 Çınarcık Earthquake. The epicenter determinations show that the first event in 04.01.1935 was located at 40.72N–27.72E, while the second one occurred at 40.61N–27.43E, indicating that both were located near the Marmara Island. Another finding is that the 1963 event was located at 40.80N–29.18E, near the Princes’ Island fault. Furthermore, moment tensor inversion method was applied on these earthquakes by using original seismograms, which provided an opportunity to illuminate the seismotectonic features of Marmara Region based on the retrieved fault mechanism solutions. For the first time, the fault mechanisms for 04.01.1935-14:41 and 16:20 Earthquakes were determined using moment tensor inversion from the original seismic waveforms. Likewise, the result obtained for the fault mechanism of 1963 Çınarcık Earthquake showed normal fault mechanism with much shallower depth than estimated before. Our preferred solutions showed that the fault mechanisms for the three events are normal faults and coincide with the seismotectonic structure of the Marmara Region.

    New insights on the tsunami recording of the May, 21, 2003, Mw 6.9Boumerdès earthquake from tidal data analysis (2015)
    Elsevier Science Limited
    Details
    Publication Date: 2021-01-27
    Description: We analyzed sea level data from a set of tide gauge stations located in the central and western Mediter-ranean Sea, that recorded the tsunami generated by the Mw 6.8 Boumerdès earthquake striking the coastof Algeria on May 21, 2003. This earthquake caused more than 2200 victims and thousands of injured. Thecausative fault was located a few kilometers offshore and during the rupture a tsunami was triggered.Waves were felt along a large part of the western and northern Mediterranean coasts, and in the Balearicislands waves higher that 2 m were measured. In this paper we analyze a more complete tidal data set,with respect to previous studies, now consisting of 22 tidal stations located in Italy, France and Spain. Tocharacterize the change of the tidal signal at each station we used the Empirical Mode Decomposition(EMD). By means of this technique, which is suitable to analyze and to characterize the dynamical behav-ior of non-stationary time series, we provide a precise measurement of the arrival times and amplitudesat the tidal stations and identify how this tsunami affected the principal and long term tidal components.Our findings improve previous results for this earthquake, since they allow the detection of significantamplitude fluctuations associated with the tsunami in the majority of stations, including the farthestones.

    Attenuation and velocity structure from diffuse coda waves: Constraints from underground array data (2015)
    Elsevier Science Limited
    Details
    Publication Date: 2021-05-12
    Description: An analysis of coda waves excited in the 0.2–20 Hz frequency band and recorded by the underground array Underseis (central Italy) has been performed to constrain both seismic attenuation at regional scale and velocity structure in the Mount Gran Sasso area. Attenuation was estimated with the MLTWA method, and shows a predominance of scattering phenomena over intrinsic absorption. The values of Qi and Qs are compatible with other estimates obtained in similar tectonic environments. Array methods allowed for a detailed study of the propagation characteristics, demonstrating that earthquake coda at frequencies greater than about 6 Hz is composed of only body waves. Coherence and spectral characteristics of seismic waves measured along the coda of local and regional earthquakes indicate that the wavefield becomes fully diffuse only in the late coda. The frequency-dependent energy partitioning between horizontal and vertical components has been also estimated and compared with synthetic values computed in a layered half-space under the diffuse field assumption. This comparison confirms that, for frequencies higher than 6 Hz, the coda appears as a sum of body waves coming from all directions while, in the low frequency range (0.2–2 Hz), the observations can be well explained by a coda wavefield composed of an equipartition mixture of surface and body waves traveling in a multiple-layered medium. A Monte-Carlo inversion has been performed to obtain a set of acceptable velocity models of the upper crust. The present results show that a broadband coda wavefield recorded in an underground environment is useful to constrain both the regional attenuation and the velocity structure of the target area, thereby complementing the results of classical array analysis of the wavefield.

    Towards Addressing CPU-Intensive Seismological Applications in Europe (2015)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2021-06-25
    Description: Advanced application environments for seismic analysis help geosci- entists to execute complex simulations to predict the behaviour of a geophysical system and potential surface observations. At the same time data collected from seismic stations must be processed comparing recorded signals with predictions. The EU-funded project VERCE (http://verce.eu/) aims to enable specific seismological use-cases and, on the basis of requirements elicited from the seis- mology community, provide a service-oriented infrastructure to deal with such challenges. In this paper we present VERCE’s architecture, in particular relating to forward and inverse modelling of Earth models and how the, largely file-based, HPC model can be combined with data streaming operations to enhance the scala- bility of experiments. We posit that the integration of services and HPC resources in an open, collaborative environment is an essential medium for the advancement of sciences of critical importance, such as seismology.

    Directional resonance variations across the Pernicana Fault, Mt Etna, in relation to brittle deformation fields (2015)
    Wiley-Blackwell
    Details
    Publication Date: 2017-04-04
    Description: The Pernicana Fault (PF) is the main structural element of Mt Etna and the northern boundary of a section sliding to the southeast. Observed ground motion records in the damage zone of the PF show strong variations of directional resonance in the horizontal plane. The observed resonance directions exhibit an abrupt rotation of azimuth by about 30◦ across the fault, varying from N166◦ on the north side to N139◦ on the south. We interpret the directional resonance observations in terms of changes in the kinematics and deformation fields on the opposite sides of the fault. The northern side is affected primarily by the left-lateral strike-slip movement, whereas the southern side, that is subjected also to sliding, is under a dominant extensional stress regime. Brittle deformation models based on the observed kinematic field predict different sets of fractures on the opposite sides of the fault: synthetic cleavages and extensional fractures are expected to dominate in the northern and southern sides, respectively. These two fracture fields have different orientations (N74◦ and N42◦, respectively) and both show a near-orthogonal relation (∼88◦ in the northern sector and ∼83◦ to the south) with the azimuth of the observed directional resonance. We conclude that the direction of the largest resonance motions is sensitive to and has transversal relationship with the dominant fracture orientation. The directional amplification is inferred to be produced by stiffness anisotropy of the fault damage zone, with larger seismic motions normal to the fractures.

    Seismic Q estimates in Umbria-Marche (central Italy): hints for the retrieval of a new attenuation law for seismic risk (2015)
    Wiley-Blackwell
    Details
    Publication Date: 2017-04-04
    Description: In the Umbria Marche (Central Italy) region an important earthquake sequence occurred in 1997, characterized by nine earthquakes with magnitudes in the range between 5 and 6, that caused important damages and causalities. In the present paper we separately estimate intrinsic- and scattering- Q −1 parameters, using the classical MLTWA approach in the assumption of a half space model. The results clearly show that the attenuation parameters Qi −1 and Qs −1 are frequency dependent. This estimate is compared with other attenuation studies carried out in the same area, and with all the other MLTWA estimates obtained till now in other tectonic environments in the Earth. The bias introduced by the half space assumption is investigated through numerical solutions of the Energy Transport equation in the more realistic assumption of a heterogeneous crust overlying a transparent mantle, with a Moho located at a depth ranging between 35 and 45 km below the surface. The bias introduced by the half space assumption is significant only at high frequency. We finally show how the attenuation estimates, calculated with different techniques, lead to different PGA decay with distance relationships, using the well known and well proven Boore’s method. This last result indicates that care must be used in selecting the correct estimate of the attenuation parameters for seismic risk purposes. We also discuss the reason why MLTWA may be chosen among all the other available techniques, due to its intrinsic stability, to obtain the right attenuation parameters.

    SPATIO-TEMPORAL MONITORING OF SEISMIC WAVE VELOCITIES IN THE UPPER CRUST (2015)
    Details
    Publication Date: 2017-04-04
    Description: Variations in seismic velocity, ratio of P -to S-wave speed (Vp/Vs), and seismic anisotropy were heralded in the 1970s and 1980s as proxies to examine the buildup of stress preceding large earthquakes. The idea is that high pressures could cause rocks to “dilate,” changing the elastic properties of the crust by increasing crack numbers and/or dimensions, thus affecting the seismic waves propagation velocities. Rock dilatancy causes the rock to undersaturate, which will strongly reduce Vp. but will have little effect on Vs. resulting in the drop of the Vp/Vs ratio (Sholz et al., 1973). Furthermore, the formation and propagation of cracks within the rock affects its anisotropic characteristic. Several studies reported changes between properties recorded before and after mainshock occurrences. A recent example is provided by Lucente et al. (2010), who reported some clear variations in the seismic wave propagation characteristics approaching a mainshock: the elastic properties of the crustal rocks in the fault region underwent a sharp change about a week before the 6 April 2009, Mw 6.3 l’Aquila earthquake. Back in the seventies, it was hoped that these kinds of studies would allow earthquake prediction to be “just around the corner” (Savage, 2010). Over the subsequent decades, this “corner” is progressively drifted away, nevertheless for seismologists, the understanding of the processes that preside over the earthquakes nucleation and the mechanics of faulting, represents a big step toward the ability to predict earthquakes. In this regard, the integration of the monitoring of the crustal proprieties variations into middle and long term forecasting tools could help in the definition of priority areas where risk reduction interventions are more urgent, with a consequent improvement in the emergency preparedness. In the framework of the guidelines defined in the general agreement DPC-INGV for the period 2012-2022, we formed a Research Unit (UR) with the aim to study the seismic property changes occurring around the fault zones to better understand the physics of the earthquake. Our final goal is to eventually provide effective, practical tools to be applied for monitoring purposes and decision making. The UR includes two Working Packages (WP) that will investigate the variation of seismic wave velocities through different approaches. The first WP will analyze the ambient seismic noise cross-correlations to estimate the relative velocity variations occurred in the Po Plain before and after the 2012 seismic sequence, and in the Pollino region (southern Apennines) shaken by multiple seismic sequences during the last years. The second WP will focus on the shear wave seismic anisotropy temporal fluctuation, through the application of a systematic study to all events recorded during the ongoing seismic sequence in the Pollino area.

    Advance Visualisation of Seismic Wave Propagation and Wave Speed Model (2015)
    Details
    Publication Date: 2018-03-06
    Description: With the induction of the Virtual Reality and Visualisation Centre (V2C) at Leibniz Supercomputing Centre (LRZ), many domain specialists have approached LRZ to leverage on the immersive projection technology. Large datasets can now be stereoscopically displayed and specialists can interact with their complex datasets intuitively. Seismologists is one group of domain specialists that have benefited from the use of this virtual reality (VR) technology. To allow a deep insight into the simulated data, the seismologists make use of VR installations like a 5 sided projection installation based on the concepts of a Carolina Cruz-Neira’s CAVE Automated Virtual Environment (CAVE). In this article, the CAVE like installation at LRZ will be referred to as the CAVE for convenience.

    A comparison of surface and underground array measurements of ambient noise recorded in Naples (Italy). (2015)
    Springer
    Details
    Publication Date: 2020-02-24
    Description: Abstract In this study, we describe two experiments of seismic noise measurements carried out in Naples, Italy. The site allowed measurements to be obtained both at the surface and in a tunnel that is 120-m-deep. The main goal was to compare the seismic response evaluated at the surface to the in-tunnel response, through spectral, polarization, and resonance directivity analyses. In the 1 to 20 Hz frequency band, the noise level was up to 15 dB higher at the surface than in the tunnel. The polarization properties and horizontal-to-vertical spectral ratios appear not to be influenced by the tunnel geometry or by the topography. Some preferential alignments were observed in the polarization azimuths computed at the surface, which are likely to be due to local sources, rather than morphological features. The absence of directivity effects and the low noise levels in the tunnel make this site suitable for installing seismic stations. We also studied how the subsoil structure affects the seismic motion at the surface. The dispersive properties of the Rayleigh waves were investigated using the spatial autocorrelation method. A joint inversion of the dispersion data and the horizontal-to-vertical spectral ratios provided the subsurface Vs profile. The derived model has a low velocity contrast at depth, such as to generate moderate and broad H/V spectral ratio peak amplitude. The normalized spectral ratio appears more appropriate to identify the soil-resonance frequencies.

    2010-2014 Seismic activity images the activated fault system in the Pollino area, at the Appennines-Calabrian arc boundary region (2015)
    Details
    Publication Date: 2017-04-04
    Description: The main goal of this study is to increase the understanding of the physical mechanisms behind the ongoing seismic activity in the Pollino area and its influence on the seismic hazard of the Apennines-Calabrian arc boundary region. The study area, near the Pollino massif, is located at the northernmost edge of the Calabrian Arc, which is the last oceanic subduction segment along the Africa-Eurasian plate. The subduction results from the sinking of the Ionian oceanic plate beneath the Calabrian Arc-Southern Tyrrhenian Sea and is part of the fragmented tectonic boundary between two macro-plates: Africa and Eurasia. The subduction geometry is well-documented by several seismological studies (i.e. Chiarabba et al., 2005), and the lithospheric structure of the area is quietly well known (i.e. Totaro et al., 2014 and Piana Agostinetti and Amato, 2009) Despite the slow N-S convergence between these major plates, the Southern Tyrrhenian Sea is a large basin characterized by E-W extensional tectonic. Since Late Miocene, the Calabrian Arc slab experienced rapid rollback, moving E to SE at a rate of 5-6 cm/yr, which is by far higher than the ~1-2 cm/yr rate of convergence between Africa and Europa (Faccenna et al., 2004). However, during late Pleistocene, rollback and subduction have slowed and is likely proceeding at less than 1 cm/yr (D’Agostino and Selvaggi., 2004). Geodetic measurements show that the Pollino Range is subject to NE-SW anti-apenninic extension. In the region the strain rate field shows a continuous belt of extensional deformation that follows the ridge of the Southern Apennines and extends in the Pollino region. The extension rate appears to decrease from the Southern Apennines to the Calabria- Lucania border region (D’Agostino et al., 2013). This finding indeed reveals that the Pollino region is deforming and accumulating tectonic strain which results in a complex system of normal active faults striking sub-parallel to the Apennines. Two principal normal faults are present in the Italian Database of the Individual Seismogenic Sources DISS version 3.1.1 (DISS Working Group, 2010) in the Pollino area: the Pollino (P) fault and the “Rimendiello-Mormanno” (RM) fault system. The RM fault is an active seismogenic structure it strikes about NNW-SSE and dips toward NE; it has hosted in its northernmost part a M 5.0 earthquake on 9th September 1998. The P fault has similar strike but dips toward SW: it shows no recent seismicity and is hence one of the most prominent seismic gaps in the Italian historical seismic catalogue (Rovida et al., 2011). Paleoseismic studies have shown that the P fault was active in the last ten thousand years and is capable to produce events with magnitude above 6.0. The DISS database reports as debated source also the Piana Perretti fault (Brozzetti et al., 2009). A detailed structural map of the area interested by the seismic sequence shows three fault systems (Brozzetti et al., 2013) consisting of several aligned fault segments that have been active during the Late Pleistocene and are reasonably presently active. The first fault system strikes NW-SE and dips toward SW (including the Piana Perretti fault at the NE edge of the Mercure Basin), the second one has similar strike and NE dip, while the third one strikes about E-W. Earthquakes reported in the historical catalogues for this area are not very strong. Few earthquakes with magnitude probably less than 6 affected the area, including the Mw=5.6 “Mercure” event in 1998 (Brozzetti et al., 2009). The Parametric Catalogue of Italian earthquakes (CPTI11, Rovida et al., 2011), shows very well the lack of strong earthquakes in the region: there is a clear evidence of large earthquakes in the Campania-Basilicata area (M~7.0) and several strong earthquakes in the Sila region and in the whole Calabrian territory. According to the seismic classification of the national territory, the area affected by the 2010-2014 seismic activity have a relatively higher probability to be shaken by a strong acceleration (Gruppo di Lavoro MPS, 2004). Most of the seismic events occurred in areas where the peak ground acceleration having 10% chance of being exceeded in next 50 years is between the values of 0.225 g and 0.275 g.
