Descripción
A seismic hazard assessment study of continental Ecuador is presented in this paper. The study begins with a revision of the available information on seismic events and the elaboration of a seismic catalog homogenized to magnitude Mw. Different seismic source definitions are revised and a new area-source model, based on geological and seismic data, is proposed. The available ground motion prediction equations for crustal and subduction sources are analyzed and selected for the tectonic environments observed in Ecuador. A probabilistic seismic hazard assessment (PSHA) approach is carried out to evaluate the exceedance probability of several levels of peak ground acceleration PGA and spectral accelerations SA(T) for periods (T) of 0.1, 0.2, 0.5, 1 and 2 s. The resulting hazard maps for continental Ecuador are presented, together with the uniform hazard spectra (UHS) of four province capital cities. Hazard disaggregation is carried out for target motions defined by the PGA values and SA(1s) expected for return periods of 475 and 2475 years, providing estimates for short-period and long-period controlling earthquakes.
