THE Philippine Institute of Volcanology and Seismology (Phivolcs) on Sunday advised residents in extreme northern Luzon to prepare for possible aftershocks after a magnitude 5.7 earthquake shook off Batanes.
The quake, which was tectonic in origin, struck at 9:43 a.m. Sunday. Its epicenter was located about 38 kilometers west of Sabtang, Batanes.
It had a depth of 10 kilometers, Phivolcs said in its advisory.
The earthquake was reportedly felt in some parts of northern Luzon, with Intensity I termors recorded in Pasuquin, Ilocos Norte.
While no damage was expected, Phivolcs noted that aftershocks were possible.
Earthquakes are a normal occurrence across the Philippines as the country sits along the Pacific Ring of Fire, a region where quakes and volcanic eruptions take place.
