Amid the devastation caused by the magnitude 6.7 earthquake in Surigao, the Philippine Institute of Volcanology and Seismology (Phivolcs) appealed to residents of Metro Manila and nearby provinces to prepare for a powerful earthquake that could kill thousands Filipinos.
“Everyone must learn from the recent effects of the magnitude 6.7 earthquake in Surigao del Norte. If a similar event happens in a highly urbanized area, the effects can be more devastating,” Phivolcs director Renato Solidum warned.
State seismologists have repeatedly warned the public that the West Valley Fault is ripe for movement.
The West Valley Fault, Solidum said, moves roughly every 400 years. The last major earthquake generated by this fault was in 1658 or 357 years ago.
The 100-kilometer fault traverses parts of Bulacan through Quezon City, Marikina, Makati, Pasig, Taguig and Muntinlupa in Metro Manila; San Pedro, Biñan, Sta. Rosa, Cabuyao and Calamba in Laguna; and Carmona, General Mariano Alvarez and Silang in Cavite.
A 2004 study funded by the Japan International Cooperation Agency for Phivolcs and the Metropolitan Manila Development Authority showed that the magnitude 7.2 quake could kill up to 34,000 people and injure 100,000 others due to collapsed buildings.
Solidum explained that the movement of the Philippine Fault (Surigao segment) would not trigger the movement of faults farther like the West Valley Fault.
As a Christian Nation, we need to pray deeply for our Country. Let us turn back to God.
