Interactive Map for the West and East Valley Fault Line on Rizal, Metro Manila, Laguna, Cavite

The West and East Valley Fault System spans from Montalban, Rizal all the way down to Carmona, Cavite and is the most feared event that could hit Metro Manila in case the fault system moves as it may cause larger than 7.0 magnitude earthquake. As of the meantime, disaster resiliency assessors have been saying that the country is not prepared for a calamity such as this. Schadow1 Expeditions has acquired the fault line data from PHIVOLCS and traced it on top of Openstreetmap and Google Earth.

We have recently acquired the fault line data for the West and East Valley Fault System from PHIVOLCS and have decided to trace the data on top of Openstreetmap Philippines and on Google Earth. This is to provide a graphical representation of the exact infrastructures that lies on top of the fault line so that everyone will be aware of the dangers and prepare for the future.

The last known activity along this fault line was the year 1658 and is estimated to be active every 300 years plus or minus 100 years. As of the time of this writing, it has been 356 years ago and is well within the potential period of its movement.

The photo above is a snapshot along the area of Muntinlupa and San Pedro, Laguna where the red line is a part of the West Valley Fault Line.


We have prepared a trace of the fault line over Google Earth and can be downloaded here.

The fault line starts at Montalban Landfill of Montalban Rizal and ends at San Lazaro Leisure Park and Casino at Carmona, Cavite. Although, recent studies of PHIVOLCS shows it still extends from Carmona to Silang and to Calamba, Laguna. We are still waiting for the precise data so we can add the fault line's extension at the interactive map. As of October 2, 2014, we have acquired the additional data and extended the fault line until Calamba, Laguna.

These are the following notable barangays, villages and infrastructure that lie exactly on top or within 500-meter radius from the fault line.
