On 10 October 2025, two powerful earthquakes struck off the coast of Manay, Davao Oriental. The first earthquake, with a magnitude of 7.4, occurred at 9:43 a.m., approximately 48 kilometers northeast of the Municipality of Manay, Davao Oriental, at a depth of 23 kilometers. … Less than ten hours later, a second earthquake with a magnitude of 6.8 struck the same offshore area at 7:12 p.m. The epicenter was located 43 kilometers southeast of the Municipality of Manay, Davao Oriental, with an estimated depth of 37 kilometers.
Both earthquakes were tectonic in origin and not related to the recent 6.9 magnitude earthquake in Cebu, which was caused by the Bogo Bay Fault. The Davao Oriental earthquakes were generated by the movement of the Philippine Trench. As the second earthquake registered a magnitude greater than 6.4, it can no longer be considered an aftershock of the main event. PHIVOLCS classified these as two separate events, referred to as a “doublet quake”, which occurred close in time and location. (IFRC, 20 Oct 2025)
