Emergency workers recovered the body of a child and his mother out of collapsed buildings in the central Philippines on Wednesday, a day after an earthquake killed at least 69 people and injured more than 200 others.

The death toll was expected to rise from the 6.9 magnitude quake that hit at about 10 p.m. on Tuesday and trapped an unspecified number of residents in the hard-hit city of Bogo and outlying rural towns in Cebu province.

On Wednesday night, emergency workers in orange and yellow hard hats used spotlights, a backhoe and bare hands to sift through the rubble of concrete slabs, broken wood and twisted iron bars for hours in a collapsed building in Bogo city.

The epicenter of the earthquake, which was set off by movement in an undersea fault line at a dangerously shallow depth of 5 kilometers (3 miles), was about 19 kilometers (12 miles) northeast of Bogo, a coastal city of about 90,000 people in Cebu province where about half of the deaths were reported, officials said.

The Philippines, one of the world’s most disaster-prone countries, is often hit by earthquakes and volcanic eruptions due to its location on the Pacific “Ring of Fire,” an arc of seismic faults around the ocean. The archipelago is also lashed by about 20 typhoons and storms each year.
