The February 2014 Cephalonia earthquake (Greece): 3D deformation field and source modeling from multiple SAR techniques

On 26 January 2014 at 13:55 UTC, an M_w 6.0 earthquake struck the island of Cephalonia, Greece, followed five hours later by an M_w 5.3 aftershock and by an M_w 5.9 event on 3 February 2014 at 03:08 UTC (National Observatory of Athens, Institute of Geodynamics [NOA‐GI]). The epicenter of the M_w 6.0 event was relocated 2 km east of the town of Lixouri, and that of the M_w 5.9 event at the tip of the Gulf of Argostoli, in the northern part of the Paliki peninsula (Fig. 1; Karastathis et al., 2014; Papadopoulos et al., 2014). Extensive structural damage and widespread environmental effects were induced throughout the Paliki peninsula and along the eastern coast of the Gulf of Argostoli (Valkaniotis et al., 2014). Quays, sidewalks, and piers were damaged in the waterfront areas of the towns of Lixouri and Argostoli, the island capital, and liquefactions, road failures, rock falls, and small landslides were observed. Most of the latter effects took place in the aftermath of the 26 January 2014 event and were reactivated one week later by the 3 February earthquake.
