After the devastating damage left by 6.7 magnitude earthquake in Surigao, the Philippine Institute of Volcanology and Seismology (Phivolcs) warned residents of Metro Manila and nearby provinces to prepare for the 'Big One'.
According to Phivolcs, the 'Big One' is a 7.2 magnitude earthquake that will be generated by the West Valley Fault which seismologists identify as ripe for movement.

The West Valley Fault passes 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.
Phivolcs director Renato Solidum said:
“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.”
A study funded by the Japan International Cooperation Agency for Phivolcs and the Metropolitan Manila Development Authority showed that up to 34,000 people could be killed and 100,000 others could be injured by 7.2 magnitude earthquake.
Phivolcs have recorded more than 150 aftershocks from the earthquake that hit Surigao, Friday night which left at least eight people dead and hundreds injured.
