MANILA – A magnitude 5.3 earthquake jolted Surigao del Sur early Thursday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.
The tectonic quake struck 63 kilometers northeast of the municipality of Bayabas at 6:10 a.m. It had a depth of 15 kilometers.
The earthquake is an aftershock of the magnitude 5.7 quake that hit the same epicenter last Sept. 21, according to Phivolcs.
Intensity IV was felt in Bayabas, while instrumental intensity I was recorded in Surigao City.
Reported intensity is the traditional way of knowing the intensity based on reports of people who felt the earthquake. Instrumental intensity, on the other hand, is being measured by intensity meter that measures ground acceleration, Phivolcs director Renato Solidum Jr. explained.
Meanwhile, Phivolcs said no damages and aftershocks are expected from the magnitude 5.3 quake.
Solidum earlier said Intensity V is not damaging yet on Phivolcs’ scale. Damage starts at Intensity VI, he said. (PNA)
