5.2 magnitude earthquake hits southern Philippines
The institute said the offshore earthquake, which struck at 7:56 a.m. local time, hit at a depth of 47 km, about 67 km southeast of Don Marcelino town on Mindanao island.
The institute said the quake, which was tectonic in origin, can trigger aftershocks but not cause damage.
The Philippines has frequent seismic activities due to its location along the quake-prone Pacific "Ring of Fire." ■
