MANILA, Oct. 17 (Xinhua) -- An earthquake with a magnitude of 5.4 shook Occidental Mindoro province south of Manila early Saturday morning, the Philippine Institute of Seismology and Volcanology (Phivolcs) said.
The institute said the quake, which struck at 4:06 a.m. local time, hit at a depth of 33 kilometers, about 23 kilometers southwest off Looc town.
The tremor was also felt in the capital city of Manila.
The institute said the quake, which was tectonic in origin, will trigger aftershocks but will not cause damage.
