Strong Quake Jolts Metro Manila, Many Luzon Areas


MANILA — A 6.3-magnitude earthquake of tectonic origin with epicenter in the waters off Nasugbu, Batangas jolted Metro Manila and many parts of Luzon at 1:28 p.m. on August 11 but there was no immediate report on damages.

The Philippine Institute of Volcanology and Seismology (Phivolcs) said Intensity IV was felt in Calapan, Mindoro; Subic, Zambales; Rosario, Cavite; Manila; and Sablayan, Occidental Mindoro, while Intensity III was recorded in Pateros City; Quezon City; Makati City; Malolos, Bulacan; Cainta, Rizal; and Calamba, Laguna.

Intensity III was felt in Puerto Galera, Oriental Mindoro; San Jose, Occidental Mindoro; Tagaytay City; Canlubang and Calamba, Laguna; Indang and Alfonso Cavite; Bocaue, Malolos, Obando and Balagtas, Bulacan; Dagupan City; Dau, Pampanga; Lingayen, Pangasinan; Bagac, Bataan; Baguio City; Pateros; Quezon City; Makati City; San Juan City; Marikina City; Cainta and San Mateo, Rizal..

It was Intensity II in Sta. Rosa, Laguna; Gasan, Marinduque; Magalang and Sto. Tomas, Pampanga; Tanauan City, Batangas, while it was Intensity I in Talisay, Batangas; Pantabangan, Nueva Ecija; Meycauayan, Bulacan; Atok, Benguet.

Phivolcs added that Intensity II was felt in Magalang, Pampanga and Tanauan City, Batangas, and Intensity I in Talisay, Batangas.

The quake  prompted the Manila and other local government units (LGUs), universities and colleges to declare class suspensions.

The tremor resulted in shaking buildings and forcing the evacuation of offices and schools throughout Metro Manila.

There were no immediate reports of deaths or injuries.

The US Geological Survey initially recorded the earthquake with a magnitude 6.6 but downgraded it to 6.2.

PHIVOLCS chief Renato Solidum said the earthquake was due to the movement of the Manila Trench.

“Ang pagyanig kanina ay isang lindol na dulot ng tinatawag na pagkilos along the Manila Trench. Ang lindol po ay malalim, 161 kilometers, kaya marami din po ang nakaramdam,” Solidum said.

Solidum said that this will not generate a tsunami due to its depth.

The earthquake’s epicenter was recorded 5 km. southwest of Lian, Batangas. Phivolcs said it is expecting aftershocks.

The National Grid Corp. of the Philippines (NGCP) has reported that its power transmission services remain normal despite the 6.3-magnitude earthquake.

In an alert, the NGCP said the grid remains intact as no power interruption has been reported.

The NGCP is still assessing if there are damaged transmission facilities in Metro Manila and surrounding areas.
