Modelación de peligro sísmico usando como herramienta el programa HAZ45.2 (segunda parte).

Abstract

Earthquakes are the most important natural phenomenon for the practice of civil engineering due to their high destructive power and their direct impact on infrastructure projects. Ecuador is located within the area known as the "ring of fire of the Pacific" so it is a country where it becomes essential to study and approximate the levels of seismic hazard to which engineering projects could be exposed in their useful life, For this purpose, the probabilistic seismic hazard analysis has become the main tool for assessing the intensity levels expected in an area based on the activity of the surrounding seismic sources. The program HAZ45.2 developed by Dr. Normam Abrahamson is an open access software that allows you to model the seismic sources with their respective geometrical and seismic characteristics to implement probabilistic analysis of seismic hazard in any site, this program apart from having the advantage of being freely available, it has also been validated with respect to other commercial software of the market that have considerable amounts of acquisition. It is the intention of the present title work to continue with what was done by Eduardo Mora and to model different relevant seismic sources in the Ecuadorian Litoral zone in order to generate seismic hazard results more and more approximate for this area of the country and additionally generate seismic hazard results for the Faculty of Engineering of the UCSG based on the modeled sources.
