A M W 6.3 earthquake struck on April 6, 2009 the Abruzzi region (central Italy) producing vast damage in L'Aquila town and surroundings. In this paper we present location geometry of fault system as obtained by analysis main shock aftershocks recorded permanent temporary networks. The distribution aftershocks, 712 selected events with L ≥ 2.3 20 4.0, defines a complex, 40 km long, NW trending extensional structure. segment extends for 15–18 dips at 45° to SW, between 10 2 depth. extent...
Abstract Wastewater injection into a high‐rate well in the Val d'Agri oilfield, largest onshore Europe, has induced swarm microseismicity since initiation of disposal 2006. To investigate reservoir structure and to track seismicity, we performed high‐spatial resolution local earthquake tomography using 1,281 natural earthquakes recorded by networks. The properties carbonate (rock fracturing, pore fluid pressure) inherited faults control occurrence spatiotemporal distribution seismicity. A...
The site response is critical for accurately estimating  source parameters, as it directly influences the spectral characteristics of seismic signals. Achieving reliable estimates these parameters requires clearly distinguishing between source effects, path attenuation, and response, which are often interdependent subject to significant trade-offs. As highlighted in recent studies, reflects amplification or damping effects shallow subsurface layers on waves, its accurate...
Machine-learning algorithms are widely applied to facilitate human tasks. For instance, in seismology, they can help deliver high-resolution seismic catalogs including very small magnitude events that usually remain undetected by analysts and standard monitoring procedures. The new frontier of modern seismology is exploit deep neural networks (DNN) automatically detect P- S-wave arrival times obtain good-quality event locations terms hypocentral errors. Increasing the number phases...
Inadequate seismic design codes can be dangerous, particularly when they underestimate the true hazard. In this study we use data from a sequence of moderate‐sized earthquakes in northeast Italy to validate and test regional wave propagation model which, turn, is used understand some weaknesses current spectra. Our velocity model, while regionalized somewhat ad hoc , consistent with geophysical observations local geology. 0.02–0.1 Hz band, validated by using it calculate moment tensor...
<p>At 01:36 UTC (03:36 local time) on August 24th 2016, an earthquake Mw 6.0 struck extensive sector of the central Apennines (coordinates: latitude 42.70° N, longitude 13.23° E, 8.0 km depth). The caused about 300 casualties and severe damage to historical buildings economic activity in area located near borders Umbria, Lazio, Abruzzo Marche regions. Istituto Nazionale di Geofisica e Vulcanologia (INGV) few minutes hypocenter Accumoli, a small town province Rieti. In hours after...
In the years between 2011 and 2014, at edge Apennines collapsing chain subducting Calabrian arc, intense seismic swarms occurred in Pollino mountain belt. this key region, &lt;2.5 mm/yr of NE-trending extension is accommodated on an intricate network normal faults, having almost same direction as The long-lasting release consisted different swarm episodes, where strongest event coinciding with a M L 5.0 shock October 2012. This latter comes after four nucleated May 2012 followed by...
ABSTRACT Earthquake hypocentral location is perhaps the most classical problem in seismology, solution of which often affected by significant uncertainty. In monitoring effects underground anthropogenic activities, earthquake location, magnitude, and ground motions are important parameters for managing induced seismicity (as e.g., operating traffic-light systems). Such decisional systems define operative reactions to be enacted once an earthquake, exceeding some magnitude or ground-motion...
Abstract. The project at hand is a field test around the KTB (Kontinentale Tiefbohrung) site in Oberpfalz, Southeastern Germany, northwestern edge of Bohemian Massif. region has been extensively studied through analysis several seismic reflection lines deployed drilling site. deep borehole had placed into gneiss rocks Zone Erbendorf-Vohenstrauss. Drilling activity lasted from 1987 to 1994, and it descended down depth 9101 m. In our experiment, we aim recover structural information as well...
Abstract Precise hypocenter locations are critical for properly interpreting earthquake occurrence processes. However, when the coverage with seismic stations is unfavorable or sparse, locating precisely hypocenters, in particular their depth, challenging. Here we apply a newly developed approach, which uses only two land stations, to recently occurred 2022 Adriatic Sea offshore sequence (mainshock of magnitude Mw 5.5) and achieve location results that comparable catalog obtained using...
In this paper, we review the procedures involved in establishing a contemporary workflow for real-time microseismic monitoring using local-scale seismographic network. We draw on our specific experience potentially induced or triggered seismicity at two adjacent oil extraction sites Basilicata region of Southern Italy. This effort is conducted within regulatory framework that adheres to established guidelines. However, perceive undertaking as generally appropriate any network, irrespective...
&lt;p&gt;Ground motion prediction equations (GMPEs) based on data collected hydrocarbon extraction areas have to deal with lower magnitude and smaller distances compared the natural seismicity. This study focuses Mirandola-Cavone oil field located in Po Plain (Northern Italy), an area that has been struck by Emilia earthquake sequence 2012.&lt;br&gt;We start compilation of a new homogeneous seismic catalogue, terms locations moment magnitudes. The come from local network run...
In this paper we describe the results of an experimental implementation recent guidelines issued by Italian regulatory body for monitoring hydrocarbon production activities. particular, report about pilot study on seismic, deformation, and pore pressure Mirandola cultivation facility in Northern Italy. This site hosts Cavone oil field that was speculated possibly influencing 2012 M L 5.8 earthquake source. According to guidelines, center should analyse geophysical measurements related...
