Seismotectonic interpretation of the 2002 Mw 4.8 Gérgal seismic sequence using seismological data and radar interferometry (INSAR)

This work analyzes the geological source of the Mw 4.8 February 4 2002, Gérgal earthquake. The interpretation of local geological data, the relocation of the aftershocks sequence using a local velocity model, the focal mechanism calculation and the interferometric study of the area using RADAR images give evidences that support a tensional stress source with a rupture plane oriented NW-SE to NNE-SSW
