A magnitude 7.8 offshore earthquake struck near Sarangani on Monday morning, June 8, killing residents, damaging buildings, and triggering tsunami warnings across parts of the region.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said the quake was caused by movement along the Cotabato Trench, a major offshore fault system linked to the deadly 1976 Moro Gulf earthquake and tsunami.
Authorities warned of possible aftershocks and maintained tsunami risk alerts in affected coastal areas.
The Philippine Coast Guard suspended watercraft operations in Davao Occidental as a precaution while monitoring sea conditions.
Emergency response operations continue as officials assess the extent of damage and casualties in quake-hit communities.
