Abstract
Laguna , Philippines is near several active faults pose a threat to the safety of people and structures. To estimate the grounds shaking level in the province, a probabilistic seismic hazard analysis (PSHA) was conducted. Also, a site-specific PSHA was conducted for Banadero, Calamba City because of the site's susceptibility to liquefaction. In conducting the PSHA, earthquake catalog from International Seismological Center (ICS) and Philippine Institute of Volcanology and Seismology (PHIVOLCS), active fault map of the Philippines and past geologic studies were used to characterize seismic sources and quantify uncertainties in distance and magnitude of future earthquakes. Seismic hazard maps were produced having return periods of 100, 475, and 975 years, at spectral ordinates of Peak Ground Acceleration (PGA), Spectral Acceleration (SA) at 0.2 sec and SA at 1.0 with 5% damping at rock soil. Design spectra, which are used as the bases of design of structures, were generated for Banadero based on the produced seismic hazard maps and considering the actual soil condition. The hazard at Banadero is dominated by Marikina Valley Fault System and Manila Trench. It was found out the seismic hazard in Banadero was dominated by the Marikina Valley Fault System and the Manila Trench.
