PHIVOLCS released on Tuesday the Valley Fault System Atlas, a collection of detailed large-scale maps that illustrates the areas that are near an earthquake fault.
The VFS is composed of two segments: the East Valley Fault running through Rizal, and the West Valley Fault, running through Bulacan, Rizal, Metro Manila, Cavite, and Laguna.
PHIVOLCS has previously warned about possible impending activity from the West Valley Fault.
"We don't usually use the word ripe because the fact would indicate that the West Valley Fault can move in our lifetime simply because the last earthquake that happened from this fault, most likely the 1658 earthquake 357 years ago, and the interval of movement of the fault is roughly between 400-600 years. So that's very close," said Solidum.
The West Valley Fault could possibly generate a magnitude 7.2 earthquake, almost as strong as the magnitude 7.8 earthquake that hit Nepal last month, while the East Valley Fault could generate a magnitude 6.2 earthquake.
In case of a magnitude 7.2 earthquake from the West Valley the fault, 31,000 to 33,500 people could die, according to estimates based on previous studies conducted by PHIVOLCS in partnership with the the Metro Manila Development Authority, Japan International Cooperation Agency, and Geosciences Australia.
The study also estimates the cost of rehabilitation at around P1.8 to 2.3 trillion.
