Aplicación de la metodología STAR para el análisis del riesgo sísmico de la provincia Bolívar – Ecuador.

Abstract

Seismic risk is the probability of occurrence of a natural adverse event, associated with human and material losses, which is established by multiplying the threat by the threat; What is intended through this research is to identify the level of seismic risk of buildings in the Bolivar province, for this the Star methodology is used, which includes a heuristic, qualitative and quantitative study, which allows us to identify the level of sensitivity In addition, the threat level of the province which was achieved through the multiplication of the Z factor established in the Ecuadorian Construction Standards and the maximum magnitude of an earthquake through the incidence of geological faults that cross the Bolivar province, to establish the value of seismic risk. Therefore, a field work was carried out applying the vulnerability matrix for information gathering. In addition, the management of the computer program called ArcGIS was applied, which specified us to delimit the levels of vulnerability and seismic risk. As a result of the study carried out, it was determined that there is a medium level of threat and threat, thus giving as a provincial seismic risk a medium level; finally, it can be concluded that in the Bolívar province a great percentage their homes have a structural system of reinforced concrete, this reduces the threat to a seismic threat, however, for future constructions, the construction regulations of each country should be considered to avoid future disaster situations.
