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.
A
possible 7.2 earthquake looms around the corner if the West Valley Fault along
the eastern side of Metro Manila cracks, Renato Solidum Jr., Philippine
Institute of Volcanology and Seismology (Phivolcs) director warns.
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.
The fault
has moved four times in the past 1,400 years. On average, it moves every 400 years,
“+/- 10 to 100 years, maybe”, Solidum says. 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 says.
All of
Manila Shaking
The
earthquake can occur anywhere along the West Valley Fault, including Metro
Manila. But 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.
Solidum
reiterates that weak, poorly designed, and poorly constructed buildings far
from the earthquake fault are still vulnerable to destruction.
Grounds
can also be affected by liquefaction, a process where loose, sandy sediments
behave like liquid, Solidum explains. It becomes weak. This can cause poorly
designed or constructed buildings and homes to subside or tilt, roads fissured,
and water banks broken.
Areas near the waters like Marikina Valley down
to Manila de Ba-i, and the coastal cities of Metro Manila are also more likely
to experience stronger ground shaking due to the softer ground they sit on.
Preparedness Begins at Home
We hear that Manila is not prepared
to handle a major disaster but there are many things we can do to
minimize the impact to your own household. Preparedness begins at home
and preparing Manila means ensuring that enough families take simple steps to look after themselves.

Preparation remains best option
Unlike storms and typhoons, earthquakes cannot be “forecasted” and can
only be predicted by looking at how often it happens in history. To
date, there are no scientific instruments that predicts when an
earthquake will occur.
Solidum says that the
possibility of a movement from the West Valley Fault is a more than
enough reason for the us to prepare for it as soon as we can.
The most important preparation measure, Solidum says, is to make sure
that buildings, houses , and infrastructures in Metro Manila are
earthquake and fire resistant.
He also says that
at the local level, the physical integrity of the buildings should be
assessed. “The issue though is some of the buildlings are non-engineered
and most likely walang permit so they have to focus on that also,” he
adds.
Major lifelines like water and power supply, and communication means should be strengthened and made fire and earthquake proof.
Another is to have an efficient relief and recovery system after the
earthquake. Solidum suggests a “bayanihan” style of relief and recovery
where provinces unaffected by the earthquake could help those that are
unaffected.
“Preparedness need not only be concentrated in Metro Manila and the surrounding provinces, but [also to] the other regions.”
First aid and rescue should be available in each community in case
major assistance cannot immediately arrive in their area after an
earthquake. — TJD/OMG, GMA News
