    Details
    Publikationsdatum: 2023-01-13
    Beschreibung: Coseismic surface faulting associated to the 6 April 2009, Mw 6.1 L'Aquila earthquake from the joint analysis of the Istituto Nazionale di Geofisica e Vulcanologia (INGV) and of the Istituto Superiore per la Protezione e la Ricerca Ambientale (ISPRA) field observations. The primary surface faulting reaches a total length of ca. 6 km and shows a ca. 3 km-long zone of continuous and consistently oriented surface ruptures in proximity of the village of Paganica, along a prominent NW-SE oriented, SW dipping normal fault. The deformation occurred in a ca. 500 m-wide zone. Secondary surface ruptures (antithetic and sympathetic) occurred along nearby faults. INGV - ISPRA joint database - 2009 L'Aquila earthquake surface rupture - Observation points: this file contains the tectonic ruptures observation points containing information about the typology, the geometrical characteristics, and a brief description of the observed feature.

    Coseismic evidence of surface faulting at the Ischia Volcanic Island after the 21 August 2017 Md 4.0 Casamicciola Earthquake (2020)
    PANGAEA
    Details
    Publikationsdatum: 2023-06-17
    Beschreibung: We provide a database of the coseismic surface ruptures produced by the 21 August 2017 Md 4.0 earthquake that struck the Casamicciola Terme village in the north of Ischia volcanic island (Italy). Despite its small size, the earthquake caused two fatalities and heavy damages in a restricted area of a few square kilometers. The shallow hypocentral depth of the earthquake caused a significant coseismic surface faulting, testified by a main alignment of ruptures mapped for a 2 km end-to-end length along the Casamicciola E-W trending normal fault system, bounding the northern slope of Mt. Epomeo. Casamicciola Terme has been recurrently destroyed in the last centuries by similar volcano-tectonic earthquakes (1762, 1767, 1796, 1828, 1881, and 1883). After the catastrophic 1883 Casamicciola event (2343 casualties), this is the first heavy damaging earthquake at Ischia that provides, for the first time, the opportunity of integrating historical seismicity, macroseismic observations, instrumental information, and detailed mapping of coseismic geological effects. We performed a detailed field surveys in the epicentral region of the 21 August earthquake to describe the ruptures geometry and kinematics of the seismogenetic fault responsible of the earthquake with the aim of contributing to the seismic hazard evaluation and land use planning in the Ischia island, one of the most crowded touristic destinations worldwide. Summarizing our study of ground effects for the 21 August 2017 earthquake is important for improving knowledge on surface earthquake in the volcanic area and contributing to complete the gap of empirical scaling relating to the surface-faulting mechanism due to small-size or moderate earthquakes in volcano-tectonic framework. The collected field observations result in a dataset of 88 georeferenced records describing coseismic ruptures/fractures by features as ID number, 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.

    Beschreibung: 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.

    Beschreibung: We provide a database that embodies more than 7000 punctual observations of the coseismic surface geological effects following the 30 October 2016 Mw 6.5 earthquake that hit central Italy. This earthquake caused widespread surface ruptures over a 〉400 km2-wide mountainous area. The Open EMERGEO Working Group, originated by the collaboration of several European geological survey teams coordinated by the Istituto Nazionale di Geofisica e Vulcanologia, involved about 130 researchers to perform detailed geological field surveys in the epicentral region. These observations mostly include accurate description of the geometry and kinematics of ground breaks caused by primary surface faulting, and subordinately by landslides due to shaking. The database consists of georeferenced records containing both numeric and string fields in the form of a suitable .txt file.

    The M6.9, 1980 Irpinia earthquake (southern Italy): joint surface ruptures dataset (2022)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: This dataset gathers all the published existing information on the coseismic surface ruptures produced by the Mw 6.9 earthquake that struck the Irpinia region (southern Italy) on the 23rd November 1980. The dataset is the sum of the observations made by several authors over the years (e.g., Carmignani et al., 1981, Westaway and Jackson, 1984, Pantosti and Valensise, 1990, Blumetti et al., 2002). The data were collected during field surveys carried out from right after the event till 2021 and were integrated by aerial photo interpretation. The most recent surveys by the authors of this database were focused on the evaluation, repositioning through GNSS handheld devices, and validation in the field of the observation points to overcome unprecise manual positioning of pre-GNSS times. The observations are organized in a database of 175 homogenous georeferenced points and 49 georeferenced lines (coseismic ruptures). The points data are available in .xlsx meanwhile the lines are available in .shp format. Each point is described by the following parameters, when available: Observation type, Latitude, Longitude, Elevation, Throw, Strike, Dip, References, Ranking, Comment, and Bibliography. The ranking assigned to each coseismic feature is based, with integrations, on Baize et al. 2021. Each feature is attributed to two ranking values, one referring to the compilers of this database and the other to the original author's interpretation. The scores are 1 to 4: 1) principal faulting; 2) simple distributed faulting; 3) sympathetic faulting; 4) ground shaking or shaking/gravity-induced slip (category assigned in this work). The lines are described by Type of observation, Uncertainty, Strike, Downthrow Side, Ranking, Comment, and Bibliography. The ranking values are the same as above. The downthrow side value for each line is the mode of the observation points located on the line itself. As a consequence of the different ages and origins of the data, including the variable scaling of the surveys, we have built the dataset at different scales; we suggest looking at the project at the scale spanning from 1:5.000 to 1:10.000.

    Unoccupied Aircraft Systems (UASs) Reveal the Morphological Changes at Stromboli Volcano (Italy) before, between, and after the 3 July and 28 August 2019 Paroxysmal Eruptions (2021)
    MDPI
    Details
    Publikationsdatum: 2024-02-07
    Beschreibung: In July and August 2019, two paroxysmal eruptions dramatically changed the morphology of the crater terrace that hosts the active vents of Stromboli volcano (Italy). Here, we document these morphological changes, by using 2259 UAS-derived photographs from eight surveys and Structure-from-Motion (SfM) photogrammetric techniques, resulting in 3D point clouds, orthomosaics, and digital surface models (DSMs) with resolution ranging from 8.1 to 12.4 cm/pixel. We focus on the morphological evolution of volcanic features and volume changes in the crater terrace and the upper part of the underlying slope (Sciara del Fuoco). We identify both crater terrace and lava field variations, with vents shifting up to 47 m and the accumulation of tephra deposits. The maximum elevation changes related to the two paroxysmal eruptions (in between May and September 2019) range from +41.4 to −26.4 m at the lava field and N crater area, respectively. Throughout September 2018–June 2020, the total volume change in the surveyed area was +447,335 m3. Despite Stromboli being one of the best-studied volcanoes worldwide, the UAS-based photogrammetry products of this study provide unprecedented high spatiotemporal resolution observations of its entire summit area, in a period when volcanic activity made the classic field inspections and helicopter overflights too risky. Routinely applied UAS operations represent an effective and evolving tool for volcanic hazard assessment and to support decision-makers involved in volcanic surveillance and civil protection operations.

    Investigating the architecture of the Paganica Fault (2009Mw6.1 earthquake, central Italy) by integrating high-resolution multiscale refraction tomography and detailed geological mapping (2018)
    Details
    Publikationsdatum: 2020-10-13
    Beschreibung: This article has been accepted for publication in Geophysical Journal Internationa ©: 2017 Published by Oxford University Press on behalf of the Royal Astronomical Society. All rights reserved.
    Beschreibung: We present a 2-D subsurface image of the Paganica Fault from a high-resolution refraction tomography and detailed geological investigation carried out across part of the northwestern segment of the 20-km-long Paganica–San Demetrio fault-system, and which was responsible of the 2009 April 6 Mw 6.1 L’Aquila earthquake (central Italy). We acquired two seismic profiles crossing the Paganica basin with a dense-wide aperture configuration. More than 30 000 P wave first-arrival traveltimes were input to a non-linear tomographic inversion. The obtained 250–300 m deep 2-D Vp images illuminate the shallow portion of the Paganica Fault, and depict additional unreported splays defining a complex half-graben structure. We interpret local thickening of low-Vp (〈2400 m s−1) and intermediate-Vp (2600–3400 m s−1) regions as syn-tectonic clasticwedges above a high-Vp (3800–5000ms−1) carbonate basement. These results are condensed in a 4.2-km-long section across the Paganica basin, clearly indicating that the Paganica Fault is a mature normal fault cutting the whole upper ∼10 km of the crust. We evaluate a minimum cumulative net displacement of 650 ± 90 m and a total heave of 530 ± 65 m accomplished by the Paganica Fault, respectively. In the conservative hypothesis that the extension started during the Gelasian (1.80–2.59 Ma),we obtain a minimum long-term slip-rate of 0.30 ± 0.07 mm yr−1 and an extension-rate of 0.25 ± 0.06 mm yr−1, respectively. Considering the regional averaged extensional field of ∼1 mm yr−1 obtained from geodetic and geological analyses at 104 yr timescale, we infer that the Paganica Fault accounts for ∼20 per cent of the NE-extension affecting this zone of the central Apennines axis due to the concurrent activity of other parallel normal fault-systems nearby (e.g. the Liri, Velino-Magnola, L’Aquila-Celano and Gran Sasso fault-systems).

    Multidisciplinary Study of Subsidence and Sinkhole Occurrences in the Acque Albule Basin (Roma, Italy) (2021)
    Wiley Agu
    Details
    Publikationsdatum: 2021-03-11
    Beschreibung: We present the results of a combined analysis of remote sensing and geophysical ‐ geotechnical data carried out in the Acque Albule Basin, a sinkhole prone area located close to the city of Roma, where a wide travertine wedge is present. We carried out geophysical measurements and borehole drillings over two test areas to image the subsoil where paroxysmal sur fi cial dynamics occur. One site is marked by subsidence occurring at least since the early 2000s, whereas the other site hosts the “ La Regina ” and “ Colonnelle ” sinkhole lakes, which discharge sulfur ‐ carbonated waters. The stability of these two sites threatens highway, railway, and airport facilities, and this study helps to assess the geological hazard. For example, InSAR and LiDAR data helped de fi ne wide scale subsidence over the last 20 years and previously undetected small ‐ scale morphologies. Geophysical measurements of the latter revealed shallow and deep dissolution affecting the travertine and driving sur fi cial paroxysmal events. Both study sites were found to lie inside a large depression located at the junction between Jurassic carbonate and Plio ‐ Pleistocene units in association with paleo karst morphologies in the travertine deposits and affected by the present ‐ past spillage of sulfurous waters. Given these elements, multidisciplinary geophysical observations are crucial for assessing and mitigating the geological risk and guiding land use planning and management.

    The contribution of airborne LiDAR data to the assessment of surface faulting hazard (2021)
    SGI
    Details
    Publikationsdatum: 2021-05-12
    Beschreibung: In case of moderate to strong earthquakes (generally for M 〉 5.5), coseismic slip along a fault can reach directly the ground surface and produce surface faulting. Although scarcely considered in the Italian legislation, surface faulting hazard can have a relevant societal impact because it exposes to substantial risk urban areas and/or important infrastructures, facilities and critical lifelines that are settled or planned in coincidence of an active and capable fault trace. In this paper we present a case study from the area hit by the Mw 6.1 April 6, 2009 L’Aquila earthquake (Central Italy), where buildings and critical lifelines located across or near the coseismic surface ruptures suffered significant damage. High resolution (1 m) LiDAR topographic data contributed to the assessment of surface faulting hazard through a better imaging of the surface geometrical arrangement of the earthquake causative fault and through the analysis of the spatial relationships between active fault splays and critical lifelines and infrastructures.

    Complexity of the 2009 L'Aquila earthquake causative fault system (Abruzzi Apennines, Italy) and effects on the Middle Aterno Quaternary basin arrangement (2019)
    Elsevier
    Details
    Publikationsdatum: 2021-06-15
    Beschreibung: An Mw 6.1, devastating earthquake, on April 6, 2009, struck the Middle Aterno Valley (Abruzzi Apennines, Italy) due to the activation of a poorly known normal fault system. Structural analysis of the fault population and investigation of the relationships with the Quaternary continental deposits through integrated field and laboratory techniques were conducted in order to reconstruct the long-term, tectono-sedimentary evolution of the basin and hypothesize the size of the fault segment. A polyphasic evolution of the Middle Aterno Valley is characterized by a conjugate, ∼E-W and ∼NS-striking fault system, during the early stage of basin development, and by a dip-slip, NW-striking fault system in a later phase. The old conjugate fault system controlled the generation of the largest sedimentary traps in the area and is responsible for the horst and graben structures within the basin. During the Early Pleistocene the E-W and NS system reactivated with dip-slip kinematics. This gave rise to intra-basin bedrock highs and a significant syn-tectonic deposition, causing variable thickness and hiatuses of the continental infill. Subsequently, since the end of the Early Pleistocene, with the inception of the NW-striking fault system, several NW-strands linked into longer splays and their activity migrated toward a leading segment affecting the Paganica-San Demetrio basin: the Paganica-San Demetrio fault alignment. The findings from this work constrain and are consistent with the subsurface basin geometry inferred from previous geophysical investigations. Notably, two major elements of the ∼E-W and ∼NS-striking faults likely act as transfer to the nearby stepping active fault systems or form the boundaries, as geometric complexities, that limit the Paganica-San Demetrio fault segment overall length to 19 ± 3 km. The resulting size of the leading fault segment is coherent with the extent of the 6 April 2009 L'Aquila earthquake causative fault. The positive match between the geologic long-term and coseismic images of the 2009 seismogenic fault highlights that the comprehensive reconstruction of the deformation history offers a unique contribution to the understanding faults seismic potential.
