Testing of a New GMPE Model in Probabilistic Seismic Hazard Analysis for the Sakhalin Region

Аннотация

The study focuses on improving the methodology and technology of detailed seismic zoning of the Sakhalin region and adjacent areas. A new regional GMPE (ground motion prediction equation) model derived from instrumental data of accelerometer and seismometer networks are considered, as well as imported new-generation advanced (NGA 2) models. The results of probabilistic seismic hazard analysis (PSHA) for Yuzhno-Sakhalinsk has made it possible to compare the hazard curves of physical parameters produced by different attenuation models. The advantages and disadvantages of the regional GMPE model are discussed based on this comparison. Practical recommendations are given.
