Overview
- The United States Geological Survey recorded the mainshock at magnitude 7.4 about 20 kilometers off Manay, Mindanao, at 9:43 a.m. local time.
- Philippine seismologists warned of a destructive tsunami and ordered evacuations, and the Pacific Tsunami Warning Center later lifted its regional alert before a fresh warning followed an aftershock.
- Authorities reported at least eight fatalities, including three miners in a collapsed gold tunnel near Pantukan, a wall-collapse death in Mati, a fatal heart attack, and another death in Davao City.
- Civil defense officials described infrastructure damage as minimal with no missing persons, yet power and communications were cut in places and a hospital in Manay treated patients outside after engineers deemed the building compromised.
- More than 800 aftershocks were logged as classes were suspended and non‑essential public employees were sent home while road clearing and damage assessments continued.
