Abstract: This study deals with the analysis of the potential seismic – induced liquefaction which is a complex ground failure phenomenon observed when saturated loose sand deposits loss its shear strength. It may be quantified as to the damage that it causes to the built infrastructures within the vicinity. This study was conducted to determine the potential liquefaction of three specific locations along the Pasig City segment of the Valley Fault System in Barangay Kapitolyo, Manggahan and Ugong and correlate it with their respective soil suitability. The study employed secondary data from geotechnical firms, DOST – PHIVOLCS and the local government unit of Pasig City. The results were assessed through the use of an excel program devised by the researchers based on a simplified procedure by Seed and Idriss (1997), and Das (1995). The factor of safety due to liquefaction (FS) at specific soil conditions was computed using this program and proved that the chosen location in barangay Ugong is the most susceptible to liquefaction among the three chosen locations. The mitigation measures for the soil and/or the type of foundations to be applied was considered and pile foundations are recommended in the locations in baranggay Manggahan and Ugong. Shallow foundations are, on the other hand, safe in barangay Kapitolyo.
