The Marikina Valley Fault runs directly beneath Metro Manila—and when it ruptures with a magnitude 7.2 earthquake, PHIVOLCS estimates 34,000 people will die in minutes. This isn’t speculation. This is science. This is “The Big One” that every Filipino fears.
In this video, we explore:

What the Marikina Valley Fault is and why it threatens all of Metro Manila
The 100-kilometer fault line cutting through Quezon City, Marikina, Pasig, Taguig, and Muntinlupa
Why magnitude 7.2 is catastrophic for a densely populated urban area
PHIVOLCS estimates: 34,000 deaths, 100,000+ injured, 2.5 trillion pesos in damage
What happens in the first 60 seconds when the shaking starts
Why 40% of Metro Manila buildings don’t meet earthquake standards
The 1990 Luzon earthquake (magnitude 7.7) that killed 1,600+ people—and why The Big One will be worse
Why the fault hasn’t ruptured in 367 years—and what that means for pressure buildup
Which Metro Manila cities are in the highest danger zones
How infrastructure will fail: water, power, roads, bridges, hospitals
Why fires could rage uncontrolled after the earthquake
What you MUST do to prepare your family before it strikes

The Marikina Valley Fault is not a distant threat. It runs through the heart of the capital. Thirteen million people live in Metro Manila. Most don’t know the fault exists. Even fewer are prepared.
The last major rupture was in 1658—367 years ago. Geologists estimate the fault ruptures every 400-600 years. We’re well within the danger window.
PHIVOLCS has been warning about The Big One for years. Computer simulations show the devastation. Government plans exist on paper. But the reality is that Metro Manila is not ready for a magnitude 7.2 earthquake.
When the Marikina Valley Fault slips, it won’t just shake buildings. It will shift the ground horizontally. Roads will split. Structures built across the fault line will be torn apart. The earthquake will last 30-60 seconds, but the damage will last decades.
This is the most important earthquake threat facing the Philippines. Not offshore trenches. Not distant fault lines. The Marikina Valley Fault is beneath Metro Manila RIGHT NOW.
Are you prepared? Does your family have supplies? Do you know what to do when the shaking starts? The Big One is coming. The only question is when.
