A moderately strong earthquake measuring magnitude 5.7 on the Richter scale rocked Bukidnon province and several parts of Mindanao on Monday evening, June 14.

The Philippine Institute of Volcanology and Seismology (Phivolcs) said the quake occurred around 10:38 p.m. and traced its epicenter at 12 kilometers northwest of Kadingilan, Bukidnon.

It was initially measured as a 5.9-magnitude quake.

Phivolcs said the tremor was shallow at a depth of 3 kilometers thus the strong shaking.

Kadingilan, Bukidnon felt the quake as a “very strong” shaking at Intensity VI.

It was also felt at Intensity V as a “strong” earthquake in Damulog and Don Carlos in Bukidnon and Wao in Lanao del Sur.

Phivolcs said it was “moderately strong” at Intensity IV in Kalilangan, Kitaotao, Pangantucan, Kibawe, Maramag, Quezon, Libona, and Talakag in Bukidnon; Cotabato City; Marawi City; Marantao, Lanao del Sur; Cagayan de Oro City; City of Iligan; and Banisilan and Pikit, Cotabato.

It was felt at Intensity III as a “weak” earthquake in Malaybalay, Baungon, Cabanglasan, Impasug-ong, Malitbog, San Fernando, Lantapan, and Manolo Fortich, Bukidnon; El Salvador, Misamis Oriental; Pagadian City; and Davao City, and at Intensity II as a “slight shaking” in Arakan and M’lang in Cotabato; Kidapawan City; Dipolog City; Datu Piang, Maguindanao; City of Bayugan, Agusan del Sur; Opol, Misamis Oriental; and Monkayo, Davao Oriental.

Meanwhile, it was “scarcely perceptible” at Intensity I in Mambajao, Camiguin and Butuan City.

Phivolcs’ instruments also recorded the quake at Intensity III in Cagayan de Oro City and Gingoog City in Misamis Oriental and Kidapawan City in North Cotabato.

It was also recorded at Intensity II in Koronadal City, South Cotabato.

The quake was tectonic in origin, which means that the tremor was caused by the movement of an active fault in the area.

Phivolcs warned that aftershocks are likely to occur due to this earthquake.

The strongest aftershocks so far were measured at magnitudes 5.0 and 4.7 at 10:49 p.m. and 10:59 p.m., respectively.
