Investigating the seismic cycle in Italy by multitemporal analysis of ALOS and ERS/ENVISAT DInSAR data sets

In this study, we performed a detailed survey of surface deformations occurred in two different regions in Italy. The first, located in Southern Italy, takes into consideration the causative fault of the 1908 Messina earthquake (Mw 7.1), that is an east-dipping normal-oblique fault lying under water along the Straits of Messina. The second site is the L´Aquila area (Central Italy), where a Mw 6.3 earthquake occurred on 6th, April 2009. The subsequent studies demonstrated that the best-fit solution for the main shock, retrieved by DInSAR data, is represented by a normal fault -16 km long and -12 km wide, with a small right-lateral component, dipping 47°SW with a maximum slip of -90 cm (Atzori et al., 2009) [1]. This study is completely carried out within the SiGRiS project, funded by the Italian Space Agency (ASI).
