Abstract:

In pursuit of testing earthquake-resilient building models, ground motion records are necessary input in the analysis. Although using actual seismic records has many advantages, there is a lack of strong ground motion records in the Philippines. To compensate these shortcomings, available records in Japan and Taiwan were used to verify the seismological model that was applied in the simulation of the time-history records. A local earthquake record was used to determine the region-specific source parameters of this model to match the local site conditions of the country. Stochastic simulations were performed to generate acceleration time-history records for scenario earthquakes in West Marikina Valley Fault with different magnitudes and distances depending on the current seismic stations in Metro Manila. The peak acceleration produced by a M7.0 earthquake corresponds to the maximum PGA estimate of 0.5g in Metro Manila while the extreme scenario of M7.2 and M7.5 produced 0.57g and 0.63g, respectively.
