GNGTS 2018 - 37° Convegno Nazionale

154 GNGTS 2018 S essione 1.1 Fig. 1 - (A, B) Simplified tectonic map; abbreviations are: SC, Sicily Channel; HP, Hyblean Plateau; CB, Caltanissetta Basin; HMEFS, Hyblean–Maltese Escarpment Fault System. The red circle indicates the area affected by the February 6-12, 2016 seismic activity. (C) Final earthquake location in map and (D) 3D sketch. Hypocentral locations were obtained by using the TomoDDPS code (Zhang et al. , 2009) and the 3D velocity model by Scarfì et al. (2018). In map, a red dotted line delimits the Giarratana sequence. (E) Modelled fault obtained by a 3D fitting of the hypocentres. (F) Best fitting focal mechanisms of the 2016 sequence, based on P-wave polarity readings. In the inset the projection of P and T directions computed.
