PROBABILISTIC AND PSEUDO-DETERMINISTIC SEISMIC HAZARD ASSESSMENT FOR NEIVA - COLOMBIA
Authors: Andrés José ALFARO CASTILLO, Mónica Andrea BOHÓRQUEZ FIERRO
Abstract fulltext
Neiva is located in a region with a significant seismic hazard due to the proximity of several active faults that have generated large earthquakes like that of February 9th, 1967 the epicenter of which was located just a few kilometers away from the city. Said earthquake caused a significant number of casualties and considerable damage. In this study, earthquakes with magnitude MS greater than 4.0 were analyzed within a 33,400 km2 area. Earthquakes of this intensity can cause victims and damages in a country such as Colombia. Peak ground acceleration is 272 gals for a 475 years return period. Pseudo-deterministic analysis shows a credible maximum acceleration of 339 gals due to the Dina Fault.
