The West Valley Fault Line is ripe for a strong earthquake. It has been 357 years since it last moved in 1658. The fault moves every 400 to 600 years, so it is close to 400 and there is a possibility that it could happen in our lifetime.
The movement can trigger a 7.2 magnitude earthquake that could be compared to the recent Nepal quake. The PHIVOLCS, MMDA and other government agencies conducted a study that if the West Valley Fault would shake in this coming years, it could cause large damages on the infrastructures, cause injury to more than a hundred thousand residents and kill more than 30,000 people.
PHIVOLCS identified the specific areas where the 100 kilometer fault line passes through in a book entitled “The Valley Fault System Atlas in Greater Metro Manila”. A copy of the book was released online for residents, local leaders, students and researchers. for public awareness on what residents should do before, during & after the earthquake .
Here’s a report from UNTV.
The West Valley fault line Rizal portion starts in Angat Dam in San Lorenzo, Norzagaray, Bulacan and continues between the boundary of Bulacan and Rizal.
While the West Valley fault line Bulacan portion runs through San Jose Del Monte affecting the towns of San Isidro, San Roque and Cuidad Real.
Then the West Valley Fault line goes through the west side of Rodriguez, Rizal, from Macabud and goes along Mayon Ave. of Metro Manila Hills Subdivision up to Amityville Subdivision, Villa Ana Maria Subdivision and Christineville Subdivision where Tagumpay Elementary School and Tagumpay National High School are located.
