MANILA – A magnitude 5.1 earthquake jolted Surigao del Norte on Monday afternoon, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.

In a bulletin issued at 5:04 p.m., Phivolcs said the tectonic quake struck 29 kilometers northeast of the municipality of General Luna at 4:07 p.m.

The quake, which was 15 kilometers deep, was earlier logged as magnitude 4.8.

Intensity IV was felt in General Luna, Surigao Del Norte; and Intensity III in Surigao City, Surigao Del Norte.

Intensity II was reported in Dapa, Surigao Del Norte; Hilongos and Baybay City, Leyte; and San Francisco, Southern Leyte.

Phivolcs also recorded the following instrumental intensities:

Intensity III – Surigao City, Surigao Del Norte
Intensity II – Mahaplag, Abuyog, and Baybay City, Leyte; San Francisco, Southern Leyte
Intensity I – Cabadbaran City, Agusan del Norte; Kalilangan, Bukidnon; Carigara, Hilongos, Dulag, and Alangalang, Leyte; Santo Niño, South Cotabato; Saint Bernard and Sogod, Southern Leyte

Reported intensity is the traditional way of knowing the intensity based on reports of people who felt the earthquake while instrumental intensity is measured using an intensity meter that measures ground acceleration.

Phivolcs said aftershocks are likely but damage is not expected from the magnitude-5.1 quake.
