A 5.8 magnitude earthquake struck off northern Mindoro Island at 12:42 a.m. Monday, the Philippine Institute of Volcanology and Seismology said.

There were no immediate reports of damage or injuries from the offshore quake that was felt at moderately strong Intensity IV in Ilijan, Batangas and in Abra de Ilog, Occidental Mindoro.

The tremor occurred 42 kilometers northeast of Mamburao at an intermediate depth of 117 kilometers. Its epicenter was also located 36 kilometers west-southwest of Batangas and 52 kilometers west-northwest of Calapan City, according to the US Geological Survey.

It was felt at Intensity III in Calapan City and Pto. Galera in Oriental Mindoro; Tagaytay City, Malate, Manila; Alabang, Muntinlupa; and Clark, Pampanga.

Intensity II was felt in Malolos, Bulacan and Intensity I in Pasay City.

The Philippines sits on the Pacific “Ring of Fire” where continental plates collide causing frequent seismic and volcanic activity.
