For too long, the national conversation has
focused solely on the West Valley Fault
(WVF) in Metro Manila. But the hard, seismic
truth is that we face multiple, catastrophic
threats-a "Big One" for EVERY major urban
center in the archipelago.
Like how our country is fragmented by
islands, every major Philippine city sits near
or on top of a different seismic time bomb.
Know your local riskโit's not just about
Manila:
* Northern & Central Luzon: Philippine Fault
Zone (PFZ, Digdig Fault), source of the 1990
M7.8 Quake.
* Iloilo/Panay: West Panay Fault, source of
the 1948 M8.2 "Lady Caycay" Quake.
* Cebu Province: Central Cebu Fault System
(CCFS).
* Central Visayas: Bohol and Negros Fault
System
* Philippine East Coast: Philippine Trench
* Northern Mindanao (CDO/Iligan): PFZ
(Central Mindanao Segment)
* Zamboanga City: Zamboanga Fault
System & threat from the Sulu and Cotabato
Trenches.
* Luzon West Coast: Manila Trench (Major
Tsunami Threat).
* Davao Region: PFZ (Davao Segment)
* Moro Gulf: Cotabato Trench (Source of the
1918 M8.3 Quake and 1976 M8.1 Quake
Know your local fault, secure your home, and
finalize your family's protocol. The recent
M6.9 Cebu Quake is a proof and a WAKE UP
CALL.
It's not just a drill.
It's reality waiting to happen.
