Cotabato Trench caused magnitude 7.8 earthquake in Mindanao? PHIVOLCS checking

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has launched a formal investigation to determine the geological origins of the recent magnitude 7.8 earthquake that struck Mindanao. Experts are currently analyzing seismic data to verify if the Cotabato Trench was the primary source of the powerful tremor. This assessment is a standard procedure to better understand the region's complex tectonic activity and fault movements. By identifying the specific fault line responsible, authorities aim to refine future disaster preparedness and hazard mapping strategies for the area. The agency continues to monitor the situation closely as they process technical information from the event.

Identifying the specific source of a major earthquake is critical for improving regional seismic hazard assessments and enhancing long-term disaster mitigation efforts.
