The study presents a deterministic spectral acceleration contour map model for the Island of Luzon (0.2 Second) and for Metro Manila (0.2 Second and 1.0 Second). It paves the way for the recognition and acceptance of an alternate seismic hazard mapping approach for the Philippines. The study used structured steps in the determination of the seismic source, its maximum credible earthquake and the utilization of a spectral acceleration formula in mapping out the value across the attenuation table. In terms of utilization, the output of the study is intended for site specific seismic hazard planning. The study's deterministic approach can be utilized for seismic analysis for major engineering structures. The study developed a trial software for the usage of the micro contour map model of Metro Manila. The software utilizes a georeferenced map model of the whole Philippines. The software and spectral acceleration contour map, when used together presents a unique/modern tool for seismic analysis and design.
