Implementación de fuentes sísmicas del Ecuador en el programa Haz 45.2.

Abstract

Ecuador is a country with high seismic hazard, thus, in some projects, it is required to perform probabilistic seismic hazard studies. In order to calculate the seismic hazard, there are several software with an elevated cost. The software HAZ 45.2 is an open-source, free seismic hazard software developed by Dr. Norm Abrahamson from the University of California at Berkeley which has been validated against commercial software. The objective of this work is to study basic aspects of probabilistic seismic hazard, to learn the use of the HAZ 45.2 software in terms of input data and possible results and to implement some of Ecuador’s seismic sources in the software. La Toma, Guayaquil-Babahoyo and an areal source near the city of Machala were modelled in the code. It is recommended that the entire seismic source file for the country with their respective uncertainties should be modelled and implemented in this software to be able to calculate the seismic hazard in any site of Ecuador.
