Finite Seismic Source Modelling by Joint Inversion of Seismic and Geodesic Data – The SISMOD Project

Abstract

The Mw 9.2 Sumatra earthquake of December 26, 2004, like other huge Earthquakes of the past, denotes the difficulty of the science to understand such extended seismic sources. In this work we intended to explain the project SISMOD that have as main purpose the deployment of a computational algorithm to perform the systematic and detailed study of extended seismic sources, independently its dimension and geometry. The method it will be structured to operate from a joint utilization of strong motions; teleseismic waveforms and geodetic data (GPS and InSAR).
