The Valley Fault System (VFS) in the Philippines, is a dominantly dextral strike-slip fault system that 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.

Threat to Metro Manila

The fault possesses a threat of a large-scale earthquake with a magnitude of 7 or higher within the Manila Metropolitan Area with death toll predicted to be as high as 35,000 and some 120,000 or higher injured and more than three million needed to be evacuated according to JICA.

Note: Recommended minimum buffer zone from the fault is 5 meters as reckoned from the both sides of the fault trace or from the edge of the deformation zone.

Fault Segments

The fault contains two major segments, known as West Valley Fault (WVF) and East Valley Fault (EVF).

West Segment

The west segment, known as the West Valley Fault (WVF) is one of the two major fault segments of the Valley Fault System that runs through the cities of Marikina, Pasig and Muntinlupa and moves in a dominantly dextral strike-slip motion. The West Fault is capable of producing large-scale earthquakes on its active phases with a magnitude of 7 or higher.

East Segment

The eastern segment, known as East Valley Fault (EVF) moves in an oblique dextral motion.

Disclaimer: The Google map of the Marikina Valley Fault Trace, which has been adapted from the PHIVOLCS Valley Fault System Atlas, is for general reference only. Please consult the Atlas as final reference.

If you find your house/building on top or within 20 meters of the trace of the Markina Valley fault on this map, refer to the official Atlas from PHIVOLCS or you may contact them for more information at Contact PHIVOLCS.
