Casualties10 deaths, 1,027 injuries

On October 10, 2025, a doublet earthquake consisting of two events measuring Mw 7.4 and 6.7–6.8 struck eastern Mindanao in the Philippines. Both events raised tsunami warnings for seven provinces and parts of Indonesia, with minor tsunami waves observed. Thousands of aftershocks were recorded.

At least 10 deaths were reported, while more than 1,027 people were injured or hospitalized across multiple provinces. Numerous provinces and localities suspended work and classes, while damage to infrastructure was widespread, with nearly 40,000 homes damaged or destroyed. Tremors were felt across Mindanao and beyond, including in Cebu and Antique in the Visayas and as far as the Bicol Region in Luzon. At least ₱2.26 billion (US$45.93 million) in damages was recorded. Following the earthquake, the United States and Japan provided aid to assist the Philippines.

The earthquake struck only eleven days after the magnitude 6.9 earthquake in Cebu; however, it was determined that these events were not related.[2][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.[2] Notable earthquakes along this zone occurred in 1992, 2012, 2021 and 2023.[5]

Earthquakes

For the first event, PHIVOLCS initially recorded a moment magnitude (Mw ) of 7.6 and a depth of 10 km (6 mi),[6] while the United States Geological Survey (USGS) put the magnitude and depth at Mww 7.4 and 59.4 km (36.9 mi), respectively.[7]

Shortly after, PHIVOLCS downgraded the magnitude to Mw 7.4 with a depth of 23 km (14 mi).[8] Intensity VI (Very strong) shaking was reported in Manay,[9] with the intensity reaching V (Strong) in Davao City,[10] and IV (Moderately strong) in Bislig, Cebu City,[11] and Antique in the Visayas,[12] and Sorsogon City in southern Luzon.[13] In Indonesia, the earthquake was also felt with an intensity of IV (Light) in Tahuna and II (Weak) in Manado.[14]

At 19:12 PHT (11:12 UTC) on October 10, a Mww  6.7 or Mw  6.8 event struck the same region.[15][16] Intensity VI (Very strong) shaking was reported in Manay, while tremors were felt as far as Zamboanga del Sur and Northern Samar.[17] PHIVOLCS considered the earthquake a separate event and classified the sequence as a doublet earthquake.[18][19] PHIVOLCS Director Teresito C. Bacolcol noted that the last large doublet earthquakes in the region were the 1992 Mindanao earthquakes, and the December 2023 Mindanao earthquake,[20] adding that doublet earthquakes are “not unique” to the Philippine Trench region.[21]

PHIVOLCS reported that both events were caused by a rupture on the Philippine Trench.[19] The USGS reported that the first events occurred due to oblique reverse faulting.[7] According to a finite fault model released by the USGS, the earthquake rupture extended about 90 km (56 mi) by 55 km (34 mi), with significant slip of up to 4.655 m (15.27 ft) estimated within a small radius of the hypocenter. The entire rupture process took just over 30 seconds with the greatest phase of seismic moment release occurring about 15 seconds after initiation.[22]

Tsunami

Mw  7.4 earthquake (first event)
Mw 6.7–6.8 earthquake (second event)

PHIVOLCS issued a tsunami warning, predicting that tsunami waves exceeding 1 m (3.3 ft) could strike Mindanao's eastern coast by 11:45 PST.[23] The tsunami warning was issued for the provinces of Davao Oriental, Dinagat Islands, Surigao del Norte, Surigao del Sur, Eastern Samar, Southern Leyte, and Leyte.[11] The Pacific Tsunami Warning Center warned of hazardous waves within 300 km (190 mi) of the epicenter[24] which raised possibility for smaller waves as far away as Palau.[25] Authorities in Indonesia issued a tsunami warning covering northern Sulawesi and Papua.[26] Johnny Pimentel, the governor of Surigao del Sur, ordered the evacuation of coastal residents.[27] Residents in Mati, Davao Oriental fled to higher ground,[28] with seawater in Barangay Dahican observed to be receding.[29] A 30 cm (12 in) wave struck Tandag.[30] In Davao City, a 7 cm (2.8 in) high tsunami was observed.[31] Tsunamis with heights of 19 cm (7.5 in) was observed in Beo, Talaud Islands Regency, 14 cm (5.5 in) was observed in Bere Bere, Morotai Island Regency, and 10 cm (3.9 in) in Talengen, Sangihe Islands Regency.[31] PHIVOLCS canceled the tsunami warning at 13:43 PST (05:43 UTC).[32]

Following the Mw  6.7–6.8 event, another tsunami warning was issued by PHIVOLCS at 19:12 PHT, covering the provinces of Surigao del Sur, Surigao del Norte, and Davao Oriental[33] and affecting up to 1.8 million people,[34] with waves forecast to reach 1 m (3 ft 3 in).[35] This warning was cancelled at 23:12 PHT.[36]

Aftershocks

As of October 16, 2025, at least 1,464 aftershocks had been recorded from the doublet earthquakes, ranging in magnitude from 1.2 to 5.8, with at least 19 of them felt.[37] The strongest aftershock recorded after the first shock was a magnitude 5.9 at 13:48 PHT (05:48 UTC) on October 10,[38] while the strongest following the second shock was a magnitude 5.7 at 19:35 PHT (11:35 UTC) on October 20.[39]

The Department of Social Welfare and Development (DSWD) reported on November 4 that a total of 379,722 families or 1,576,540 persons were affected; 294,807 families or 1,276,665 individuals were residents of Davao Region while 84,915 families or 299,875 individuals were from Caraga Region. Of this figure, 87,767 people in 23,249 families were displaced, of which 38,512 were served inside evacuation centers.

Government

The Office of Civil Defense (OCD) held a briefing regarding the earthquake,[118] with President Bongbong Marcos directed numerous agencies to assess the situation in Davao and told Filipinos to "stay calm"[119] and told the frontline agencies the next day to work "round-the-clock".[120] The Philippine Coast Guard temporarily suspended sea travels in Eastern Visayas[121] and Southeastern Mindanao;[122] the suspensions were eventually lifted that same day upon expiration of the tsunami advisory.[123] The Bureau of Fire Protection (BFP)[124] and the Armed Forces of the Philippines were deployed to help assist with relief efforts[125] while the Davao and Caraga regional headquarters of the Philippine National Police were placed on "full alert".[80] The BFP started inspecting structures in Butuan.[126] The Department of Public Works and Highways started clearing operations in Davao Oriental.[127] The Civil Aeronautics Board of the Philippines urged airlines to provide flexible arrangements to passengers affected and also asked them to assist relief efforts.[128]

The OCD Region XI conducted an aerial assessment of the damage caused by the earthquake.[129] The DSWD in Tarragona, Davao Oriental held child-friendly activities to assist children affected by the earthquake.[130] The National Disaster Risk Reduction and Management Council (NDRRMC) placed its operations on red alert.[131] It reported on October 12 that a total of ₱26.5 million (US$538,123.17) worth of assistance had been provided to a total of 70,676 affected families from Davao and Caraga regions.[132] The Philippine Army deployed soldiers to Davao Oriental, Davao de Oro, Davao del Norte, and Agusan del Sur to assist in emergency and relief operations.[133]

Vice President Sara Duterte visited Davao Oriental to express sympathy and assured support through the Office of the Vice President’s Davao Satellite Office.[134] President Marcos also visited Davao Oriental and pledged assistance.[135] Marcos ordered the release of 298 million (US$6.05 million) in aid to local government units in the Davao and Caraga Region hit by the twin earthquakes. His office provided 50 million (US$1.02 million) to Davao Oriental and varying amounts to other affected areas.[136]

International

The U.S. government prepositioned 137,000 food packs and shelter kits, while the Japanese government, through the Japan International Cooperation Agency, provided emergency relief goods to the Philippines after the doublet earthquake.[137] The United Nations stated that it was prepared to send aid to Davao Oriental.[138]
