Residents were jolted from their beds and ran onto the streets as the earthquake shook the area, leaving cracks in a hospital, two government buildings and a port, as well as triggering the collapse of at least one house and causing a brief power outage.

“The floor appeared to rise first before swaying violently from side to side. Then the lights went out,” said Adrian Morallas, who was at work at the civil defense office in General Santos city at the time of the quake.

“I ducked and took cover under my desk in line with our disaster training, though it was very difficult to do that in the dark with the ground shaking.”

Morallas said coastal communities near General Santos were told to evacuate as a precaution, though authorities do not know how many people actually left their homes.

The quake struck at a depth of 41 kilometers (25 miles) off Mindanao island, the US Geological Service said.

The state-run Philippine Institute of Volcanology and Seismology gave a higher magnitude reading of 7.2. The epicenter was about 53 kilometers off Mindanao’s south coast, it added.
