GPS-based source inversion within the German Indonesian Early Warning System

Hochschule Neubrandenburg, 2013

Abstract: The aim of this master thesis is to work out algorithms to solve an underdetermined inverse problem in the context of the German Indonesian Early Warning System. The slip distribution, the localization of the solution and the magnitude of the earthquake will be calculated, depending on the shifting of the GPS sensors. Kaczmarz method, Landweber algorithm, Richardson iteration, Least Squares method, Tykonov Regularization via QR factorization and Least Norm via Singular Value Decomposition are examined and their stability, sensibility are tested. Furthermore, the magnitude is computed by using the Rupture Generator. The sensitivity of the GPS sensors is used to restrict the system of equations, to get a proper solution.
