70 GNGTS 2014 S essione 1.1 Fig. 3 – Refined locations of the seismicity recorded by permanent and temporary seismic stations from October 2011 to March 2013. The Top Image shows a map of the epicenters. We identify two main clusters: the first one to the W which include the M L =5.0 event and the second one to the E where the M L =4.3 occurred. The hypocenters, in section 3, depict a ball-shaped seismogenic volume. The hypocenters, in section 5, depict three seismogenic faults.
