MANILA – Surigao del Sur was struck by a magnitude 5.4 earthquake on Friday afternoon.
According to a bulletin released at 6:30 p.m. by the Philippine Institute of Volcanology and Seismology (Phivolcs), the tectonic quake occurred 89 kilometers southeast of Cagwait at 5:28 p.m. It had a depth of 16 kilometers.
Intensity IV (moderately strong) was reported in Cagwait, while Intensity II (slightly felt) was felt in Bislig.
Phivolcs also recorded the following instrumental intensities
Intensity III (weak) – City of Tandag, Surigao del Sur
Intensity II – Nabunturan, Davao de Oro

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 measured using an intensity meter that measures ground acceleration.
Meanwhile, Phivolcs said both aftershocks and damage are unlikely from the magnitude 5.4 quake. (PNA)
