On September 30, 2025, at 21:59:43 PST (13:59:43 UTC), an earthquake with a magnitude of 6.9 on the moment magnitude scale (Mw ) struck the Visayas archipelago in the Philippines. It was the strongest earthquake ever recorded in northern Cebu and the deadliest in the country since 2013, with its epicenter located off the coast of Cebu Province in the Central Visayas region.
The earthquake was felt in all of Central Visayas while also felt in some areas of Western Visayas, Eastern Visayas, Mindanao and Southern Luzon (particularly Bicol). Thousands of aftershocks were recorded. PHIVOLCS confirmed that the newly named Bogo Bay Fault was the source of the earthquake after documenting surface ruptures and fault scarps in Bogo City.
The earthquake killed at least 68 people and injured 559 others. A total of ₱3 billion( US$ 60.91 million) worth of infrastructure was damaged. Numerous buildings and houses collapsed, including churches and hospitals, with damage occurring as far away as Cebu City. Tsunami advisories were triggered, widespread power outages occurred and landslides caused damage. In response, schools were closed in several parts of the Visayas archipelago. Teams were deployed as the government supported relief efforts. Following the earthquake, most countries expressed their readiness to assist the Philippines.
The Philippine Islands are situated within a highly deformed zone between the convergent boundary of the Eurasian and Philippine Sea plates, known as the Philippine Mobile Belt (PMB). Along the east, the Philippine Sea plate subducts beneath the islands at the Philippine and East Luzon trenches. Major subduction complexes are also active along the southwestern coast of Mindanao at the Cotabato Trench and along the Manila Trench of the west Luzon. [1] [2]
Running through the PMB is the Philippine fault system; a large 1,200-kilometer-long, highly segmented strike-slip fault system. This left-lateral system of faults runs from southeastern Mindanao to northwestern Luzon. Strike-slip deformation within the PMB occurs as a result of oblique subduction of the Philippine Sea plate, where the Philippine fault system accommodates much of it. [3] The PMB has numerous subduction zones which either dip west or east depending on the location. [4]
In the center of the PMB is the Visayas archipelago which is bounded in the west by the Negros Trench and the Mindoro Collision Zone. Mesozoic and sedimentary formations are exposed but are unbearably covered by Paleogene and Neogene formations. These sedimentary formations are then covered by Plio-Pleistocene rocks. A large portion of these formations become an anticlinorium directed NNE originating from multiple tectonic events. Rock units in central Cebu are divided into three units which are divided by shear zones trending NE. Three of these shear zones are identified as possible faults, particularly the Uling-Masaba Fault, Lutac-Jaclupan Fault, and an unnamed fault. [5]
PHIVOLCS reported that between 1885 and 2013, Cebu and nearby provinces experienced at least eight strong earthquakes with magnitudes from M5.0 to M7.2, including ones recorded in 2012 and 2013. [6] Cebu was not known to be as seismically active as other regions in central Philippines as there were barely any known faults which have generated earthquakes. [7]
The earthquake struck at 21:59:43 PST on September 30, with an epicenter that was located 11 km (6.8 mi) off the eastern coast of Daanbantayan in Cebu Province, Central Visayas and at a depth of 5 km (3.1 mi). [8] The United States Geological Survey (USGS) and the Philippine Institute of Volcanology and Seismology (PHIVOLCS) both reported a moment magnitude (Mw ) of 6.9. [8] [9]
Analysis suggests that the 2025 event occurred in a region that had accumulated pressure from the 2017 Leyte earthquake. [10] PHIVOLCS described the event as the strongest earthquake ever recorded in northern Cebu. [11]
On October 1, PHIVOLCS identified the fault that caused the earthquake. It was previously unnamed and rarely detected due to its underwater location, and it had not shown any significant movement for more than 400 years. [12] [13] PHIVOLCS stated that even though minor earthquakes with magnitudes below 4.5 were recorded in the area, they were too weak to indicate the presence of a fault that could cause an earthquake. [14] On October 3, PHIVOLCS confirmed that the newly named Bogo Bay Fault was the source of the earthquake, after its Quick Response Team documented surface ruptures and fault scarps in Bogo. [15] PHIVOLCS reported that the drone surveys revealed the fault may extend up to 1.5 km (0.93 mi), [16] adding that the fault appeared to have moved in a right-lateral manner. [17]
A maximum Modified Mercalli intensity of IX (Violent) was estimated by the USGS; according to their Prompt Assessment of Global Earthquakes for Response service, approximately 59,000 people were within the zone of intensity IX, in multiple barangays of Daanbantayan and Medellin, with 315,000 others in Tabogon, San Remigio and Bogo exposed to MMI VIII (Severe) shakings. An additional three million people were exposed to VI-VII (Strong-Very strong) shaking in Cebu, Leyte, Masbate and Negros Occidental provinces; MMI VI was felt in Cebu City. MMI V (Moderate) shaking was felt by 11.12 million people across the Visayas and nearby areas, including Iloilo, Bacolod, Samar, Bohol and Roxas City. [8] The earthquake was felt as far away as Quezon in Luzon [18] and Davao del Sur in Mindanao. [19] On the PHIVOLCS earthquake intensity scale, a maximum intensity of VII (Destructive) was instrumentally recorded at Cebu City, Daanbantayan, Bogo, Medellin and San Remigio. [20] Shaking in areas near the epicenter lasted approximately 30 seconds. [21]
Aftershocks continued to be experienced after the initial mainshock. [22] By October 3, 2025, at least 4,161 aftershocks were recorded, [23] the strongest being a mb 5.3 event at 05:39 PST on October 3. [24] The aftershocks were recorded at magnitudes of 1.0-5.1, with 21 of them being felt. [23]
As of October 3,2025 [update] , the National Disaster Risk Reduction and Management Council reported that 366,360 people were affected, with 77,022 displaced from their homes. Additionally, 5,013 houses were damaged, of which 658 were destroyed. [25] The Visayan Electric Company reported power outages in some areas. [26] The National Grid Corporation of the Philippines (NGCP) said that the earthquake disconnected Leyte, Samar, and parts of Bohol from the Cebu-Negros-Panay grid. It also recorded damage to its Daanbantayan Substation and the tripping of four 230k V transmission lines in the Visayas. [27] Twenty-seven power stations failed, resulting in power outages that affected 819,843 consumers across 309 municipalities. [28] Business operations in the Philippines were disrupted when the Cebu IT Park was evacuated. [29] Power outages also occurred in Iloilo City. [30]
Several sinkholes appeared in Daanbantayan and Medellin. [31] [32]
An estimated ₱3 billion( US$ 60.91 million) in infrastructure was damaged. [33] Collapsed structures include the Archdiocesan Shrine of Santa Rosa de Lima church in Daanbantayan, a bridge in San Remigio, [34] [35] and three structures in Bantayan. [36] [37] In addition, three government buildings and six bridges were also damaged in the province. [38] [39] Some 5,587 classrooms sustained minor damage, 803 sustained major damage, and 1,187 were destroyed, [40] with more than 19,000 students and 950 teachers and staff affected.

Numerous roads in Tabuelan were damaged. [48] [9] A McDonald's restaurant collapsed. [49] One bridge in Tabogon, four bridges in Tuburan, and one road in Daanbantayan were destroyed. Housing facilities like SM Cares Housing and Condor Lodge in Bogo also collapsed. A landslide was triggered in Tabuelan while a fire broke out in SM Consolacion. [50]
In Ormoc, the city's Superdome partially collapsed. The earthquake triggered a landslide in Villaba, Leyte, blocking a main road and disrupting local transportation. [51] Another landslide occurred and a bridge was damaged in the town of Leyte. In Naval, Biliran, a gym sustained damage. [52] Many buildings were damaged in Cebu City, including the city hall, [53] Fort San Pedro [54] and a shopping mall which suffered a collapsed ceiling.

[71] One person survived after falling into a sinkhole in San Remigio generated by the earthquake. [72]
On October 3, the NDRRMC lowered the death toll from 72 to 68 after validation by the Department of the Interior and Local Government-led Management of the Dead and Missing cluster. A civil defense official said the numbers may still change as validation is still ongoing. [73]
Schools were ordered closed in Negros Occidental [74] and in Mandaue, Lapu-Lapu City, Talisay, Danao, Minglanilla, Consolacion, Carmen, and Barili in Cebu on October 1. [75] Classes in Cebu City were suspended as a precautionary measure. [9] Government work at the Iloilo Provincial Capitol was suspended to allow for an assessment of the building's structural integrity. In Tagbilaran, Bohol, government work was also suspended, except for the city's earthquake quick response team. [26] The municipality of San Remigio announced its intention to declare a state of calamity in order to expedite response and relief operations. [76] Cebu was placed in a state of calamity. [77]
Medical teams from the Cebu South Medical Center and other organizations were deployed to areas affected by the earthquake. [78] In Bogo, residents lay in tents while charging their phones using generators according to Rappler correspondent John Sitchon. Sitchon recalled the aftermath reminiscent of Typhoon Rai (Odette) but also said the aftermath a "nightmare". [79] A civil defense official said the earthquake was deadly because it struck at night, when people were asleep and slower to react. [80]
The Archdiocese of Cebu, under its new Archbishop Alberto Uy – whose formal installation occurred just a few hours before the earthquake struck – halted church use in earthquake-hit areas and ordered structural assessments of all churches and rectories.
