Major 8.2 earthquake hits off Mindanao coast in Philippines; tsunami alert issued

A powerful earthquake struck off the coast of Mindanao in the southern Philippines on Monday, prompting tsunami warnings in the Philippines and Indonesia and triggering alerts from international monitoring agencies as authorities assessed the impact across the region.

The German Research Centre for Geosciences (GFZ) said the earthquake measured 8.2 in magnitude and struck at a depth of 10km (6.2 miles). The agency had earlier estimated the quake at 7.3 before revising its assessment.

The US Tsunami Warning System issued a tsunami threat notice following the earthquake, while the Pacific Tsunami Warning Center warned that tsunami waves could affect coastal areas around the region.


In the Philippines, the Philippine Institute of Volcanology and Seismology (Phivolcs) estimated the earthquake at magnitude 7.0 and warned of possible damage and tsunami waves exceeding one metre. The agency said the waves could continue for several hours after the initial quake.

Indonesia's Meteorology, Climatology and Geophysics Agency (BMKG) put the earthquake's magnitude at 7.7 and also issued a tsunami warning.

There were no immediate reports of major damage or fatalities in either the Philippines or Indonesia, although authorities reported strong shaking in areas closest to the epicentre.

Benjie Ancheta, police chief of Alabel town in Sarangani province in the southern Philippines, said cracks appeared in the local police station building immediately after the earthquake struck during a flag-raising ceremony.

Ancheta said there were no immediate reports of casualties, though several people fainted following the strong tremor.

"This is the strongest earthquake we've experienced," Reuters reported citing Ancheta.

Witnesses in Manado, a city in northern Indonesia, also reported feeling intense shaking from the quake.

The earthquake struck offshore near Mindanao, the Philippines' second-largest island, which lies in one of the world's most seismically active regions.

The Philippines and Indonesia sit along the Pacific Ring of Fire, a vast belt of tectonic activity stretching from South America to the Russian Far East that is prone to frequent earthquakes and volcanic eruptions.

Authorities in the affected countries continued monitoring sea conditions and assessing potential damage as tsunami alerts remained in effect.
