Abstract

We analyzed ENVISAT and ALOS/PALSAR images before and after the 22 February 2006 Mozambique earthquake (Mw7.0) to obtain coseismic and postseismic displacements. Although coherence of interferometric image is low due to C-band of ENVISAT/ASAR, we obtained coseismic displacement larger than 40cm around the surface rupture. A fault model with two segments explains the observed fringe pattern fairly well and suggests that source fault is significantly larger than the surface rupture. Postseismic displacement was also observed till the end of 2006. Especially, about 50km long linear offset in fringe of 1-2cm was revealed north of the surface rupture.
