Phivolcs says Marikina West Valley fault line "ripe for movement," DPWH and MMDA conduct precautionary measures
24 Oras report
The Philippine Institute of Volcanology and Seismology (Phivolcs) said yesterday that the Marikina Valley fault line is "ripe for movement," reports GMA News Online.
"Napakataas ng probability na gumalaw ito in the future, hindi lang natin masabi ang exact date and time," Phivolcs Deputy Director Bartolome Bautista said. ("There is a high probability that it will move in the future; we just cannot say the exact date and time.")
Bautista said the fault line, supposedly capable of producing a magnitude-7.2 quake, moves every 200 to 400 years. He said the fault last moved 200 years ago. Because "iba-iba ’yong pag-uugali ng faults (faults move differently)," he said the Phivolcs is relying on pre-quake shocks to monitor its movement.
If the West Valley fault moves and causes a massive earthquake, the cities of Marikina, Quezon, Pasig, Makati, Pateros, Taguig and Muntinlupa will suffer the most, according to a Metro Manila Earthquake Impact Reduction Study.
In a 24 Oras report, the Department of Public Works and Highways (DPWH) said yesterday that they are checking more than 1,000 schools, hospitals and government offices in Metro Manila. Ten buildings, such as tenement houses in Tondo, Sta. Ana and Taguig, were declared condemned. As for some buildings, the DPWH has instructed the management to reconstruct.
Meanwhile, the Metropolitan Manila Development Authority (MMDA) is mobilizing about 3,000 employees and volunteers for the disaster response program "Oplan Yanig," Inquirer.net reported yesterday.
MMDA Assistant General Manager Emerson Carlos said the 3,000 people-backed by necessary equipment-have "adequate training in rescue operations, road clearing, restoring communication lines, retrieval operations and evacuation management." He added that the personnel have assisted victims of previous calamities like Tropical Storm Ondoy.
