    Description: We provide a database of the coseismic surface ruptures produced by the 26 December 2018 Mw 4.9 earthquake that struck the eastern flank of Mt. Etna (southern Italy), the largest active volcano in Europe. Despite its small size, this shallow earthquake caused an impressive system of coseismic surface ruptures extending about 8.5 km, along the trace of the NNW-trending active Fiandaca Fault. We performed detailed field surveys were performed in the epicentral region to describe the ruptures geometry and kinematics. These exhibit a dominant right-oblique sense of slip with coseismic displacement peaks of 0.35 m. The Fiandaca Fault is part of a complex active faults system affecting the eastern flank of Mt. Etna. Its seismic history indicates a prominent surface-faulting potential, so our study is essential for unravelling the seismotectonics of shallow earthquakes in volcanic settings, and contributes updating empirical scaling laws relating moderate-sized earthquakes and surface faulting. The collected observations have been parsed and organized in a concise database consisting of 874 homogeneous georeferenced records. The main features describing the coseismic ruptures are the following: ID, time of sample collection, location (latitude, longitude, elevation), type of rupture, type of affected substratum, attitude (dip angle, dip direction, strike), surface offset (opening, throw, strike slip, net slip), kinematics, slip vector attitude, width of the deformation zone.

    QQuake, a QGIS Plugin for Loading Seismological Data From Web Services (2021)
    Frontiers
    Details
    Publication Date: 2021-05-12
    Description: An increasing number of web services providing convenient access to seismological data have become available in recent years. A huge effort at multiple levels was required to achieve this goal and the seismological community was engaged in the standardization of both data formats and web services. Although access to seismological data is much easier than in the past, users encounter problems because of the large number of web services, and due to the complexity of the discipline-specific data encodings. In addition, instead of adopting cross-disciplinary standards such as those by the Open Geospatial Consortium (OGC), most seismological web services created their own standards, primarily those by the International Federation of Digital Seismograph Networks (FDSN). This article introduces “QQuake,” a plugin for QGIS—the Open Source Geographic Information System—that aims at making access to seismological data easier. The plugin is based on an Open Source code available on GitHub, and it is designed in a modular and customizable way, allowing users to easily include new web services.

    Insights on the European Fault-Source Model (EFSM20) as input to the 2020 update of the European Seismic Hazard Model (ESHM20) (2021)
    Details
    Publication Date: 2021-05-12
    Description: The H2020 Project SERA (WP25-JRA3; http://www.sera-eu.org) is committed to updating and extending the 2013 European Seismic Hazard Model (ESHM13; Woessner et al., 2015, Bull. Earthquake Eng.) to form the basis of the next revision of the European seismic design code (CEN-EC8). Following the probabilistic framework established for ESHM13, the 2020 update (ESHM20) requires a continent-wide seismogenic model based on input from earthquake catalogs, tectonic information, and active faulting. The development of the European Fault-Source Model (EFSM20) fulfills the requirements related to active faulting. EFSM20 has two main categories of seismogenic faults: crustal faults and subduction systems. Crustal faults are meant to provide the hazard model with seismicity rates in a variety of tectonic contexts, including onshore and offshore active plate margins and plate interiors. Subduction systems are meant to provide the hazard model with both slab interface and intraslab seismicity rates. The model covers an area that encompasses a buffer of 300 km around all target European countries (except for Overseas Countries and Territories, OTCs), and a maximum of 300 km depth for slabs. The compilation of EFSM20 relies heavily on publicly available datasets and voluntarily contributed datasets spanning large regions, as well as solicited local contributions in specific areas of interest. The current status of the EFSM20 compilation includes 1,256 records of crustal faults for a total length of ~92,906 km and four subduction systems, namely the Gibraltar Arc, Calabrian Arc, Hellenic Arc, and Cyprus Arc. In this contribution, we present the curation of the main datasets and their associated information, the criteria for the prioritization and harmonization across the region, and the main strategy for transferring the earthquake fault-source input to the hazard modelers. The final version of EFSM20 will be made available through standard web services published in the EFEHR (http://www.efehr.org) and EPOS (https://www.seismofaults.eu) platforms adopting FAIR data principles. The SERA project received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No.730900.

    Surface ruptures database related to the 26 December 2018, MW 4.9 Mt. Etna earthquake, southern Italy (2020)

    Publication Date: 2020-02-11
    Description: We provide a database of the surface ruptures produced by the 26 December 2018 Mw 4.9 earthquake that struck the eastern flank of Mt. Etna volcano in Sicily (southern Italy). Despite its relatively small magnitude, this shallow earthquake caused about 8 km of surface faulting, along the trace of the NNW-trending active Fiandaca Fault. Detailed field surveys have been performed in the epicentral area to map the ruptures and to characterize their kinematics. The surface ruptures show a dominant right-oblique sense of displacement with an average slip of about 0.09 m and a maximum value of 0.35 m. We have parsed and organized all observations in a concise database, with 932 homogeneous georeferenced records. The Fiandaca Fault is part of the complex active Timpe faults system affecting the eastern flank of Etna, and its seismic history indicates a prominent surface-faulting potential. Therefore, this database is essential for unravelling the seismotectonics of shallow earthquakes in volcanic areas, and contributes updating empirical scaling regressions that relate magnitude and extent of surface faulting.

    Establishing integrated virtual access (VA) to data and services for Engineering Seismology: the VA3 work package of the EU project SERA (2018)
    Details
    Publication Date: 2019-03-26
    Description: Virtual Access (VA) is an effective form to grant data provisions to scientists and professionals. The VA3 of the EU project SERA (www.sera-eu.org) aims to offer data and services for engineering seismology. The data provisions are constituted by well-established European-wise Research Infrastructures (RI) coordinated and hosted at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), namely the Engineering Strong Motion database (ESM), the European Archive of Historical Earthquake Data (AHEAD), and the European Database of Seismogenic Faults (EDSF). These RI are part of the seismological services of the ESFRI research infrastructure EPOS (European Plate Observing System). The challenge of this VA project is to put together three different data types in terms of nature, source, and collection strategy but share the same end-users’ community. Past attempts in relating these data types do exists, but they were performed on a very focused task based goal (e.g. seismic hazard studies), and not meant to establish a permanent relation embedded into each database structure. In this presentation, we will illustrate how the three different services are being integrated in an end-user-oriented infrastructure. This newly-designed tool will allow users to access the data they need and receive support on their use through a single access point and in a transparent way relative to the variety, needs, and routines of the data producers. The SERA project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No.730900.

    Il terremoto di Fleri (Etna) del 26 dicembre 2018 Mw 4.9. Parte II: rilievo degli effetti di fagliazione cosismica superficiale (2020)
    Details
    Publication Date: 2020-02-06
    Description: Il terremoto del 26 dicembre 2019, ore 02:19 UTC, che ha colpito il basso versante sud-orientale dell’Etna, ha prodotto non solo danni gravi e distruzioni nell’area epicentrale, pari al grado 8 EMS (Azzaro et al., in questo volume), ma anche vistose rotture superficiali lungo la faglia di Fiandaca, che è la struttura più meridionale del sistema tettonico delle Timpe (Fig. 1a). Gli effetti di fagliazione cosismica in area etnea sono storicamente piuttosto frequenti in occasione di terremoti superficiali (〈 2-3 km), anche per valori di magnitudo relativamente modesti (M ≥ 3.5, vedi Azzaro, 1999). Con una magnitudo Mw 4.9 (Regional Centroid Moment Tensors, https://doi.org/10.13127/rcmt/italy), il terremoto in questione rappresenta l’evento più significativo, in termini di entità e complessità della fagliazione associata, verificatosi nell’area etnea negli ultimi 70 anni, con una estensione della rottura superiore rispetto a quelle storiche (〈 6.5 km). Il gruppo di emergenza per il rilievo degli effetti geologici cosismici EMERGEO (http://emergeo.ingv.it) dell’INGV, si è pertanto attivato effettuando quattro campagne di misura con squadre che si sono alternate sul terreno (per un totale di 60 gg/persona), supportate da personale del proprio Centro Operativo per l’organizzazione dei dati e il popolamento del database (43 gg/persona). Il rilievo ha consentito la raccolta e catalogazione di circa 900 punti di misura relativi a posizionamento, geometria, rigetto e cinematica delle fratture cosismiche.

    Surface ruptures following the 26 December 2018, Mw 4.9, Mt. Etna earthquake, Sicily (Italy) (2020)
    Details
    Publication Date: 2020-02-06
    Description: We present a 1:10,000 scale map of the coseismic surface ruptures following the 26 December 2018 Mw 4.9 earthquake that struck the eastern flank of Mt. Etna volcano (southern Italy). Detailed rupture mapping is based on extensive field surveys in the epicentral region. Despite the small size of the event, we were able to document surface faulting for about 8 km along the trace of the NNW-trending active Fiandaca Fault, belonging to the Timpe tectonic system in the eastern flank of the volcano. The mapped ruptures are characterized in most cases by perceivable opening and by a dominant right-oblique sense of slip, with an average slip of about 0.09 m and a peak value of 0.35 m. It is also noteworthy that the ruptures vary significantly in their kinematic expression, denoting locally high degree of complexity of the surface faulting.
