Overview
- The quake, measured at magnitude 7.8 by the USGS, struck offshore southern Mindanao on Monday with a shallow depth of about 24–35 kilometers and produced very strong local shaking.
- Phivolcs and the Pacific Tsunami Warning Center issued tsunami alerts for parts of the Philippines and neighboring coasts and many communities evacuated, though most regional tsunami warnings were later downgraded or canceled after destructive waves did not materialize widely.
- Preliminary official reports show rising casualties with dozens confirmed dead, hundreds injured and several people missing as rescue teams search collapsed buildings and landslide sites in General Santos, Sarangani and nearby areas.
- Multiple strong aftershocks, some reported up to about magnitude 6.4–6.7, have continued to rattle the region and have complicated search and relief efforts while power, phone service and transport links remain disrupted in many towns.
- President Ferdinand Marcos Jr. ordered a coordinated multi-agency emergency response, suspended classes in affected areas and opened evacuation centers as authorities assess damage and prepare longer-term aid and shelter for displaced families.
