Processo de rotura do sismo Mw 7.0 de 2006 em Moçambique inferido através de dados sísmicos e de SAR.

Abstract

This work is about the rupture process of the 2006 earthquake in Mozambique inferred from different types of data (seismic and SAR). We used 38 body waves from tele-seismic stations, two SAR images acquired by ENVISAT satellite and the map of surface faulting along the Machaze fault (Feton and Bommer, 2006), to study this earthquake. The model of rupture was determined by the body waves inversion and were used this parameters: strike = 165º, dip =76 º and rake = -90º; The model showed good results for a fault plane with 40.6km long and 29 km wide. The model of the displacement was obtained from the Okada equations and it revealed a displacement consistent with the maximum displacement of 86.8 cm observed in the interferogram and the vertical displacements measurements by Fenton and Bommer (2006).
