5.5-magnitude quake jolts Mindanao areas–Phivolcs

ZAMBOANGA CITY—An earthquake rocked some parts of Mindanao on Monday afternoon, the Philippine Institute of Volcanology and Seismology said.

Rommel Allan Labayog of Phivolcs here said the 5.5-magnitude quake, which occurred at 2:56 p.m. offshore of Cotabato, was tectonic in origin.

The tremor was felt at Intensity 2 in Zamboanga City, he said. It was also felt in Davao City.

“These are all initial data. We are still monitoring …,” Labayog said.

Some Cotabato City residents said the quake was “just mild.”
