A magnitude 4.6 earthquake struck the waters off Manay, Davao Oriental at 4:58 p.m. on Tuesday, October 14, 2025.
The Philippine Institute of Volcanology and Seismology (Phivolcs) confirmed that the tremor was an aftershock of the powerful quake that hit the province earlier.
Phivolcs said the quake was tectonic in origin, caused by movements along active fault lines beneath the seabed of Davao Oriental.
No damage or casualties were reported, but authorities advised residents to remain cautious as aftershocks may still occur in the coming days.
The 4.6-magnitude quake followed the twin earthquakes that jolted the same province on October 10, measuring magnitude 7.4 and 6.8 respectively.
Those major quakes triggered tsunami warnings, damaged homes and infrastructure, and caused landslides across several coastal and upland communities.
At least seven people were killed while dozens sustained injuries when the powerful tremors struck off the coast of Davao Oriental.
Phivolcs has since recorded over a thousand aftershocks, with some reaching magnitudes between 4.0 and 5.8 across nearby Mindanao provinces.
Experts said these aftershocks were part of the ongoing adjustment of the Earth’s crust following the strong main events last week.
Local disaster offices continue to monitor the situation closely while conducting safety checks and public information drives in affected municipalities.
Authorities reminded residents to remain calm but alert and to rely only on official updates from Phivolcs and local government agencies.
Davao Oriental, situated along the Philippine Trench, has a long history of strong offshore earthquakes and remains one of the country’s most seismically active regions.
