MANILA, Nov. 17 (Xinhua) -- An offshore earthquake with a preliminary magnitude of 7.2 rocked Davao Occidental in the southern Philippines on Friday afternoon, the Philippine Institute of Volcanology and Seismology said.
The institute said the quake, which occurred at 4:14 p.m. local time (GMT 0814), hit at a depth of 10 kilometers, about 30 kilometers southwest of Sarangani town.
The institute said the tectonic quake will trigger aftershocks and cause damage. There are no immediate reports of damage or injury.
The tremor was also felt strongly in nearby areas on Mindanao island, including General Santos City and nearby provinces.
The archipelagic Philippines has frequent seismic activities due to its location along the Pacific "Ring of Fire."
