Residents in vast swaths of Mindanao should be on the lookout for possible landslides following a deadly earthquake that left at least 4 dead across the south, the Philippine Institute of Volcanology and Seismology said Thursday.
The magnitude 6.3 tremor struck about 22 kilometers southeast of Tulunan, North Cotabato Wednesday night, leaving at least 60 injured across Mindanao, opening cracks in buildings, and knocking power out.
"Iyong mga matatarik na lugar, lalo na sa may Intensity 7 at 6... Sa mga aftershocks o di kaya'y may malakas na pag-ulan, baka magkaroon din ng landslide," Phivolcs Director Renato Solidum told radio DZMM.
(Steep areas, especially those that experienced Intensity 7 and 6 shaking, there could be landslides during aftershocks or heavy rains.)
The tectonic tremor was felt at a "destructive" intensity 7 in Tulunan and M'Lang in North Cotabato and neighboring Kidapawan City, while a "very strong" intensity 6 shaking was felt in Digos City, Davao del Sur; Sto. Nino, South Cotabato; and Tacurong City, Phivolcs earlier said.
Aftershocks could be strong and capable of causing severe damage, Solidum earlier said.
"Some [aftershocks] can be felt most likely in low intensities. But we cannot remove the possibility of similar intensities that can be felt in the epicentral area," he warned.
The quake, he maintained, was not strong enough to cause a tsunami, which should have happened "30 minutes or less" after the tremor.
Scores of residents scrambled away from the coastline of Davao province on Thursday due to a false tsunami warning when the water receded during low tide.
