Scenario for strong earthquakes in the Central Valley of Costa Rica

Abstract

A series of simulations of moderate magnitude earthquakes were carried out near the Central Valley
of Costa Rica. These simulations were used to calibrate a velocity model and adjust a range of frequencies that would allow to obtain the best fit between the observed and synthetic data. With this information, simulations of scenarios of strong events of different magnitude that could occur in some of the faults surrounding the central region of the country were generated. The results are a series of maps showing the maximum velocities that could be obtained in the rock stratum without taking into account the phenomena of seismic amplification by soft soils.
