Earthquake in the Philippines
On October 10, 2025, at 09:43:59 PST (01:43:59 UTC), a 7.4–7.5 earthquake struck eastern Mindanao in the Philippines.[2] The earthquake struck only nine days after another magnitude 6.9 earthquake in Cebu.[3]
Tectonic setting
The Philippine Trench runs east of the Philippine archipelago, and represents a major subduction zone where the Philippine Sea plate subducts westwards. At its southern portion, it runs north–south from the eastern coast of Mindanao to the northern part of Halmahera Island in Indonesia.[4] The convergence rate along the trench varies from 3.2–5.4 cm (1.3–2.1 in) per year.[5] Notable earthquakes along this zone occurred in 2012, 2021 and 2023.
Earthquake
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) recorded a moment magnitude (Mw ) of 7.5 and a depth of 20 km (12 mi),[6]while the United States Geological Survey (USGS) put the magnitude and depth at Mww 7.4 and 58.1 km (36.1 mi), respectively.[2] The earthquake was followed by a Mw 5.9 aftershock eight minutes afterwards.[7]
Tsunami
PHIVOLCS issued a tsunami alert, predicting that tsunami waves exceeding 1 m (3.3 ft) could strike Mindanao’s eastern coast by 11:45 PST.[8] Tsunami alerts were issued for the provinces of Davao Oriental, Dinagat Islands, Surigao del Norte, Surigao del Sur, Eastern Samar, Southern Leyte, and Leyte.[9] The Pacific Tsunami Warning Center warned of hazardous waves within 300 km (190 mi) of the epicenter.[10]
Impact
Numerous structures were damaged in the town of Manay. Two teachers fainted when the earthquake struck a coliseum in the town. Hanging lamps and electric posts were seen shaking in General Santos. Classes were suspended in Koronadal due to the tremor.[8] Classes were suspended also in Davao City and Cotabato.[11] Workers from the Misamis Oriental capitol building in Cagayan de Oro rushed outdoors.[12]
Response
The Office of Civil Defense held a briefing in lieu of the earthquake.[13]
