Snapshot: The Big One

The 100-kilometer West Valley Fault is one of the two major segments of the Marikina Valley Fault SystemThe 100-kilometer West Valley Fault is one of the two major segments of the Marikina Valley Fault SystemThe Philippines has had its share of strong and major quakes in the 21st century, including the 7.2-magnitude earthquake that jolted Bohol in 2013. Metro Manila has largely been spared, but experts say the West Valley Fault that cuts across seven cities and four provinces should be on the cusp of an active phase, having generated its last major event in 1658. This “earthquake source” has been discovered to have a recurrence interval of 400 years to 500 years.

From 2002 to 2004, the Metropolitan Manila Earthquake Impact Reduction Study (MMEIRS) had looked at 18 scenario earthquakes before trimming these down and presenting damage analyses for three models—Model 08 (West Valley Fault M.7.2), Model 13 (Manila Trench M.7.9) and Model 18 (Manila Bay M.6.5).

Deemed the worst case, West Valley Fault M.7.2 is The Big One expected to hit Metro Manila and its nearest neighbors.

The West Valley Fault is one of the two major segments of the Valley Fault System (also known as the Marikina Valley Fault System), the other segment being East Valley Fault.

According to the MMEIRS, “the Valley Fault System… is considered to potentially cause the largest impact to the Metropolitan Manila area should it generate a large earthquake. Many research studies indicate that active phases of the Valley Fault are approaching and the estimated magnitude will be around 7 or more.”

The study estimated that The Big One will topple or damage almost half of all residential structures and up to 35% of public buildings in Metro Manila. This will directly result in about 114,000 injuries, and the deaths of some 34,000 individuals within the first hour of the quake alone. Fires caused by short circuits and gas leaks could trigger a secondary disaster, increasing the death toll by 18,000.

The impact of The Big One, the study found, could split Metro Manila into four due to fires, collapsed structures and broken road networks—the western portion; Caloocan, Malabon, Navotas, Valenzuela in the north; Las Piñas, Makati, Muntinlupa, Parañaque, Pasay, Pateros and Taguig in the south; and Marikina, Mandaluyong, Pasig, Quezon City and San Juan in the east.

The quake, which could last for as long as 30 seconds, may be felt at Intensity VIII (very destructive shaking) in Metro Manila. At this level on the Philippine Institute of Volcanology and Seismology Earthquake Intensity Scale or PEIS, people will have difficulty remaining upright even on solid ground. At Intensity VIII, railway tracks may bend or break, cracks may appear on the ground, posts and monuments may fall over or tilt, trees may shake, and water and sewer pipes may burst or bend.

The Big One might also be felt at Intensity VI (very strong shaking) in Batangas, and Intensity IV to V (moderately strong to strong shaking) in surrounding areas, including Bulacan, Rizal, Cavite and Laguna. (Photos by: NRCP.DOST.GOV.PH)
