Abstract
MAK-BAN Geothermal Power Plant is the fourth largest geothermal power plant in the world, located in the mountains of Mt. Makiling and Mt. Banahaw, in the provinces of Laguna, Quezon, and Batangas. A deterministic seismic hazard analysis was conducted to estimate the horizontal ground shaking level at the power plant. It is found out that the governing earthquake in the site is the West Valley Fault-3 which can produce a Mw 7.2 earthquake and resulting PGA for rock and stiff soil conditions of 0.33g and 0.57g respectively. Design response spectra were produced using the values of spectral coordinates of PGA, Spatial Acceleration (SA) at 0.2 sec and 1.0 sec, with 5% damping. Fragility curves for the cooling towers of the power plant were developed using the calculated spectral accelerations in accordance with the methodology provided by the Federal Emergency Management Agency (FEMA). These fragility curves are composed of four damage states namely: slight/minor, moderate, extensive, and complete damage. The conditional probabilities of being in or exceeding these damage states given a PGA of 0.57g were computed and there is a 70% chance of complete structural damage. These values can be used to create an estimate for the direct economic losses, number of casualties
