MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) on Thursday inspected the West Valley Fault in an effort to mitigate the risks that come with an active fault.

The fault spans 90 to 100 kilometers and passes through several areas in Metro Manila as well as Bulacan, Rizal, Cavite and Laguna.

Philvolcs said the fault is still very active.

“Makikita natin na madalas kumilos ang fault. Kailangan paghandaan ang pagkilos ng fault na ito,” said Phivolcs director Renato Solidum.

The agency wants to determine how often the fault moves and how intense the movement is.

“Posibleng magnitude 7.2 dito sa fault manggaling ang lindol at intensity 8 to intensity 9 shaking. Ang intensity 8 destructive earthquake na ‘yon,” Solidum said.

Soil samples from the West Valley Fault will be sent abroad for analysis.

Results are expected within two months and will be used to help government prepare for the effects of another massive earthquake.

Meanwhile, the National Disaster Risk Reduction and Management Council (NDRRMC) also conducted a nationwide earthquake drill Thursday.

NDRRMC executive director Benito Ramos said they have been doing the drills every quarter to raise awareness since no one really knows when the next big earthquake will strike next.

Residents of Negros Oriental are still reeling from the 6.9-magnitude earthquake that hit the province last month.

Aside from the dozens of fatalities, many lost their homes and millions of pesos of infrastructure were destroyed.

The cause of the earthquake was a blind fault—a fault line that had been previously undiscovered. -- Reports from Jasmin Romero, ABS-CBN News; ANC
