Descrição

In this work we suggest an algorithm for space-time seismic slip distribution on finite faults for large earthquakes, from sets of teleseismic and strong ground motion waveforms. The solution of an auxiliary linear programming problem is an essential part of the developed method. To test the algorithm and examine the stability, non-uniqueness and robustness we applied it to a set of synthetic data obtained from the solution of a forward problem based on the representation theorem applied to slip distribution schemes as real models. Were used green functions to near field stations, calculated by a finite differences method and 3D structure model. The likeness between the inversion and the known solution support the credibility to use this method with data of real earthquakes.
