The Philippine Institute of Volcanology and Seismology (Phivolcs) has assured that the first-ever Metro Manila Subway is safe and less vulnerable to the impact of earthquakes.
According to PHIVOLCS OIC Usec. Renato Solidum, no segment of the Metro Manila Subway Project runs over the West Valley Fault which is capable of producing earthquakes with a magnitude of 7 or higher.
The alignment of the subway will also pass through an adobe layer, which is ideal for tunneling, Solidum said.
Solidum also noted that underground rail is less risky than elevated rail during an earthquake.
The other reasons are its alignment towards the Ninoy Aquino International Airport Terminal 3, the terminus, is farther from the fault line and that its designers consulted the Phivolcs.
The Department of Transportation (DoTr) is also optimistic with Japan’s extensive experience and expertise in designing, building, and operating safe and reliable subway systems under seismic conditions that are more challenging than Metro Manila’s.
The DoTr started construction of the subway this week with completion and operation of the first three stations expected by 2022.
