Power transmission services in Luzon have remained normal despite the magnitude-6.3 quake that struck Batangas on Friday afternoon, the National Grid Corporation of the Philippines said.
In a power advisory posted on its Facebook page an hour after the strong quake shook the Batangas area at about 1:28 p.m., the NGCP said that no power interruption was reported.
“The grid remains intact as there have been no reported cases of power interruptions after the quake. But the NGCP is still assessing if there are damaged transmission facilities in Metro Manila and surrounding areas,” the advisory said.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the epicenter of the quake was located in Lian, Batangas, with a depth of 160 kilometers.
The quake was felt at Intensity IV in Manila; Calapan, Mindoro; Subic, Zambales; Rosario, Cavite; and Sablayan, Oriental Mindoro.
Intensity III was felt in Pateros; Quezon City; Makati City; Malolos, Bulacan; Cainta, Rizal; Calamba, Laguna.
It was Intensity II in Magalang, Pampanga and Tanauan City, Batangas, while Intensity I was felt in Talisay, Batangas.
Buildings shook, forcing the evacuation of offices and schools throughout Metro Manila.
In early July, the magnitude-6.5 quake jolted Leyte caused damage to some NGCP facilities in Eastern Visayas, resulting in widespread power interruption that lasted for weeks.
Several provinces—including Southern Leyte and Samar in Eastern Visayas; and Bohol in Central Visayas—experienced total loss of electricity that was only fully restored after three weeks. —LBG/KVD, GMA News
