Procesamiento digital de señales sísmicas del Cluster Pisayambo usando SAC (Seismic Analysis Code) y tomografía de rayos en matlab

Abstract

The goal of this thesis is to develop a seismic tomography software on two dimensions, with the purpose to apply it to the events generated into Pisayambo’s cluster. Starting with introduction about Fermat´s minimum time principle, that permits resolve forward problem, tracing ray, all well as tomography inverse problem. To solve inverse problem was used the probabilistic solution of Tarantola-Valette that was developed using Matlab. It was performed testing software with synthetic models for the purpose of controlling its reliability. Finally the software was applied to seismic events generated into Pisayambo’s cluster. This was chosen for being one of the most active regions in of Ecuador. Finally a first velocity model representing the internal structure of the lithosphere of the region Pisayambo was obtained.
