⚠️ DUE TO THE STRONG EARTHQUAKE THAT HAPPENED IN CEBU, TALKS ABOUT "THE BIG ONE" WAS RAISED AGAIN
This isn't a scare — it's a reminder that earthquakes are NOT predicted when, where, or how hard it will hit.
🌀 How bad can it get?
According to estimates, up to 50,000 deaths could possibly be killed if a massive earthquake called “The Big One.” hits.
Some incorrectly believe this is Magnitude 9 — but according to PHIVOLCS, The Big One at West Valley Fault is estimated to be at Magnitude 7.2, not 9. (Magnitude 9 usually occurs in subduction zones, not in the Valley Fault System.) )
Ano What is the West Valley Fault?
This fault goes through the following areas, according to PHIVOLCS:
âś… Quezon City (eastern side)
âś… Marikina (western side)
âś… Pasig (western part)
âś… Makati (eastern part)
âś… Taguig
âś… Muntinlupa
âś… Laguna above Sierra Madre
If it moves, thousands of lives could possibly be affected, especially in highly populated areas.
âť— NOT ONLY METRO MANILA SHOULD BE PREPARED
Earthquake can happen anywhere in the Philippines:
âś” Cebu Fault (Bogo earthquake)
âś” West Valley Fault (Luzon)
âś” Eastern Philippine Fault
âś” Central Leyte Fault
✔ Davao–Cotabato Fault System.. and many more.
In addition, according to DOST Sec. Renato Solidum, even if only a magnitude 6.5 earthquake hit the West Valley Fault, it is possible that thousands of people would have died. Meanwhile, the fault that caused the magnitude 6.9 earthquake in Bogo City, Cebu last moved 400 years ago according to PHIVOLCS — proof that sleep is not fault forever.
âś… What to do NOW:
âś” Prepare a go-bag / emergency kit
âś” Know the family evacuation plan
âś” Get your house and building assessed
âś” Contact the barangay and LGU
âś” Avoid fault lines and landslide-prone areas
Not only Metro Manila but the whole Philippines should be ready for The Big One!
