  • The ‘Next Big One’ quake in Metro Manila could happen in this lifetime, experts calculated based on historical records
  • A possible magnitude 7.2 earthquake looms around the corner if the West Valley Fault along the eastern side of Metro Manila cracks
  • On average, the fault moves every 400 years and the last time an earthquake occurred was about 355 years ago

The ‘Next Big One’ quake in Metro Manila could befall us in this lifetime, experts have calculated based on historical records.

In an article posted on GMA News, it said that Philippine Institute of Volcanology and Seismology (Phivolcs) Director Renato Solidum Jr.warned that a possible magnitude-7.2 earthquake looms around the corner if the West Valley Fault along the eastern side of Metro Manila cracks.

Solidum explained that the fault has moved four times in the past 1,400 years. On average, it moves every 400 years, “+/- 10 to 100 years, maybe.” The last time an earthquake occurred along the West Valley fault was in 1658, around 355 years ago.

“It can happen within our generation or the next generation,” Solidum noted.

The West Valley Fault runs from the heights of Sierra Madre down to Laguna. It crosses the eastern side of Quezon City, western side of Marikina, western part of Pasig, eastern part of Makati, parts of Taguig, and Muntinlupa.

Twin quakes

Just this Saturday, April 8, a twin earthquake rocked Metro Manila and nearby provinces.

The Phivolcs said a magnitude 5.6 quake first struck at 3:07 p.m., off Mabini, Batangas. The United States Geological Survey (USGS), on the other hand, put it at 5.7.

The next quake was a magnitude 6.0 tremor at 3:09 p.m., also in the same area, as disclosed by Phivolcs. USGS earlier said this tremor had a magnitude of 5.9.
