The Marikina Valley Fault System, also known as the Valley Fault System (VFS), is a dominantly dextral strike-slip fault system in Luzon, Philippines. It extends from Dingalan, Aurora in the north and runs through the cities of Quezon, Marikina, Pasig, Makati, Parañaque, Taguig, and the provinces of Laguna and Cavite.^[1]

57 subdivisions or residential villages are transected by the West Valley Fault, a 100-kilometer active fault that can generate a 7.2-magnitude earthquake.^[2]
