MANILA, March 8 (Xinhua) -- An earthquake with a preliminary magnitude of 6.1 hit waters off Davao Oriental province in the southern Philippines on Friday afternoon, the Philippine Institute of Volcanology and Seismology said.
The institute said the quake, which occurred at 05:11 p.m. local time (0911 GMT), hit at a depth of 105 km, about 149 km southeast of Governor Generoso.
The institute said the tectonic quake will trigger aftershocks but will not cause damage.
The archipelagic Philippines has frequent seismic activities due to its location along the Pacific "Ring of Fire." ■
