Enriching seismic network catalogues is a key object to understand the seismotectonic processes and hazard. In areas with poor knowledge of patterns, installation dense local networks essential. The enhanced density coverage improves detection events low energy. Nowadays, Machine Learning (ML) techniques are becoming widely used in seismology, addition standard automatic procedures (i.e., STA/LTA-based algorithms).In this study, we assess performance P- S-wave picking earthquake algorithms...
Abstract We have provided the first estimate of scattering and intrinsic attenuation for Gargano Promontory (Southern Italy) analyzing 190 local earthquakes with M L ranging from 1.0 to 2.8.

High Agri Valley is an intermontane basin of the axial portion Southern Apennines (Southern Italy), characterized by a very strong seismogenic potential. Indeed, &#160;Mw=7.0&#160; earthquake occurred in 1857. Currently, seismic networks managed ENI Oil Company and INGV, installed area, continuously record low-magnitude natural seismicity. Furthermore, two anthropogenic clusters are documented distinct sectors valley, located NE SW artificial Pertusillo lake, respectively. The first...
Abstract We have provided the first estimate of scattering and intrinsic attenuation for Gargano Promontory (Southern Italy) analyzing 190 local earthquakes with M L ranging from 1.0 to 2.8. To separate \({Q}_{i}\) \({Q}_{s}\) quality factors Wennerberg approach (1993), we measured direct S waves coda (\({Q}_{\beta }\), \({Q}_{c}\)) in same volume crust. \({Q}_{\beta }\) parameter is derived normalization method (Aki, 1980) \({Q}_{c}\) factor envelope decay (Sato, 1977). selected by...
We found a previously unreported later seismic phase from intermediate-depth and deep earthquakes of the Southern Tyrrhenian subduction zone recorded by European stations. Later phases are useful to constrain local-scale discontinuities, especially in zones, but their observation is infrequent, since it depends on stations distribution slab geometry. Their detection, therefore, great opportunity improve our knowledge systems Earth&#8217;s interior. They also represent powerful mean...
&lt;p&gt;The High Agri Valley (HAV) is an intermountain basin, located in the axial zone of Southern Apennines. It characterized by a very high seismic hazard, as testified 1857 M&lt;sub&gt;W&lt;/sub&gt; 7 Basilicata earthquake and present widespread activity well. The strong seismogenic potential area strictly related to geologic evolution Apennines turn its complex tectonic configuration.&lt;/p&gt;&lt;p&gt;In addition natural low-magnitude seismicity...
We have found a previously unreported seismic phase in seismograms of European stations from intermediate-depth and deep earthquakes the Southern Tyrrhenian subduction zone. observe this at 6 to 9 degrees epicentre, towards north. Only located well-defined region slab, depth range 215–320 km, show secondary phase. In work, we describe nature possible origin provide simple 2D model explain observed arrival times. Our analyses reveal that propagates downward narrow, high velocity layer,...
