Abstract

Probabilistic seismic hazard analyses were carried out for Central Manila and Los Baños, Laguna. The main tectonic features that effect both sites are Manila Trench, Valley FAult and AeaSource 3 defined by this study. Maximum credible earthquake magnitudes (Mw>5.0) of faults were computed from fault rupture length area sources were adapted from Koo et al (2009). Updated attenuation relationships from Pacific Earthquake Engineering Research center (PEER) were used. The highest hazards for Central Manila had a Spectral acceleration (Sa(0.2)) of 1.69g at 0.2 second period 7.38 magnitude and 141.07 km hypocentral distance. Similarly, the hazards for Los Baños had a Sa(0.2) of1.86g, 7.36 magnitude and 131.70km hypocentral distance. Results of site selection and deaggregation by magnitude are validated using related past studies.
