Earthquakes are impossible to predict but, based on historical records, Metro Manila’s West Valley Fault is due for the Next Big One within our lifetimes.
Following the magnitude 6.7 earthquake that caused devastation in Surigao, the Philippine Institute of Volcanology and Seismology (Phivolcs) has issued a warning on the “Big One,” a powerful earthquake that could kill thousands of residents of Metro Manila and nearby provinces.
Though the earthquake can occur anywhere along the West Valley Fault, including Metro Manila, a 7.2 magnitude earthquake can shake the ground even a hundred kilometers away, which means that it can shake the whole of Metro Manila and its surrounding provinces.
The West Valley Fault that 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.
Weak, poorly designed, and poorly constructed buildings far from the earthquake fault are still vulnerable to destruction.
Furthermore, the expected movement of Manila trench in the West Philippine Sea might cause a devastating tsunami in the 14 coastal towns of Pangasinan.
“Everyone must learn from the recent effects of the magnitude 6.7 earthquake in Surigao del Norte. If a similar event happens in a highly urbanized area, the effects can be more devastating,” Phivolcs director Renato Solidum warned.
PDRRMC spokesperson Avenix Arenas also said that Bulacan, Metro Manila up to Southern Luzon will the most quake and tsunami affected areas.
Recent studies show that a 32-feet-tsunami could be generated by the upcoming disastrous earthquake. Residents in the coastal areas of the affected areas should prepare anytime for the quake could possibly strike anytime.
