MANILA — A magnitude 5.5 quake struck waters off the southern province of Davao Occidental on Friday, a day after a powerful tremor rumbled across Mindanao, state seismologists said.
The latest quake hit 334 kilometers southeast of Saranggani town around 10:30 a.m. At a depth of 33 kilometers, no intensity was reported for the tremor, said Phivolcs.
The tectonic temblor is not expected to cause damage but may spawn aftershocks, added the agency.
Thursday's magnitude 6.5 quake destroyed roads and buildings that withstood 2 powerful tremors on Tuesday and last Oct. 16.
The 3 earthquakes had a combined death toll of 23 with 2 others missing and 618 injured, the National Disaster Risk Reduction and Management Council said.
The Philippines straddles the Pacific "Ring of Fire," an arc of intense seismic activity that stretches from Japan through Southeast Asia and across the Pacific basin. The archipelago tallies about 20 earthquakes a day, Phivolcs earlier said.
