Quakes? No worry—Phivolcs
‘World not ending’ as active faults move for series of jolts
The origin of a quake is just too deep to be affected by extreme weather conditions, said Mylene Enriquez, PHIVOLCS seismologist. “Quakes are just normal. On the average, there are about 20 tremors a day. It just so happened that the active faults were the ones that recently moved, triggering tremors of bigger magnitudes,” she told the Manila Standard. Enriquez dispelled speculation that “the end of the world is already approaching.” “Of course not,” she said. “People just don’t notice that quakes do happen every day.” She also said the increase in the frequency of earthquakes does not necessarily mean a bigger one is going to happen. A magnitude-5.3 earthquake rocked Surigao del Norte Friday at 1:26 p.m., with its epicenter located 71 kilometers southeast of General Luna. Intensity 2 was felt in Gingoog City and Intensity 1 in Surigao City. PHIVOLCS recorded 54 aftershocks, Enriquez said. A magnitude-4 earthquake shook Leyte province on Friday morning, PHIVOLCS said. There was no expected damage and aftershocks from the temblor that struck 7 kilometers. northeast of Albuera, Leyte at 10:44 a.m. The earthquake was felt at Intensity 3 in Ormoc City and nearby towns. There was no immediate report of damage or injuries due to the quake, PHIVOLCS said. The fault line that moved is within the Leyte Island fault line, which is part of the 1,200-km.-long Philippine fault zone, a major tectonic feature that transects the whole Philippine archipelago from northwestern Luzon to southeastern Mindanao. The ground shaking occurred three days after the magnitude-6.5 earthquake in San Julian, Eastern Samar that rocked Eastern Visayas province Tuesday afternoon. The tectonic quake, with a depth of 17 km., struck 19 km. northwest of the coastal town of San Julian, located 163 km. northeast of Tacloban. The fault line in San Julian town moved 22 times with reported intensities from Tuesday afternoon to Friday morning. The strongest aftershock was just an hour after the strong quake at magnitude 4.6. The latest was recorded at 9:48 a.m. at magnitude 2.4. At 3 a.m. Friday, a magnitude 4.4 earthquake jolted Ilocos Norte, PHIVOLCS said. The tremor’s epicenter, was traced to10 kilometers southwest of San Nicolas town. Intensity 4 was felt in San Nicolas while Intensity 3 was felt in Sarrat. The tremor was also felt in Sinait and Vigan City in Ilocos Sur and Pasuquin and Laoag City in Ilocos Norte.
