A 4.8 magnitude earthquake struck off Lubang Island in Occidental Mindoro at 7:14 p.m. on Saturday.
The tectonic quake centered 137 km northwest of Lubang at a depth of 31 kilometers, the Philippine Institute of Volcanology and Seismology said.
There were no immediate reports of casualties or damage and Phivolcs was not expecting aftershocks.
Tectonic earthquakes occur when there is a sudden release of energy in the earth’s crust due to the movement of tectonic plates.
Earthquakes are a common occurrence in the Philippines, which lies on the Pacific “Ring of Fire,” a region prone to earthquakes and volcanic eruptions due to the movement of tectonic plates.
The most devastating earthquake in recent Philippine history was the magnitude 7.2 earthquake that struck Bohol in 2013, which killed more than 200 people and caused widespread damage to infrastructure.
