2025 Powerful Earthquake Hits Philippines
On September 30, 2025, at 21:59:43 PHT (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.

The earthquake killed at least 75 people and injured 1,271 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.

Eleven days after the Cebu earthquake, another pair of earthquakes struck eastern Mindanao; however, it was determined that the two events were unrelated.[1]
Tectonic setting
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 western Luzon.[2][3]

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.[4] The PMB has numerous subduction zones which dip either west or east depending on the location.[5]

In the center of the PMB is the Visayas archipelago, 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.[6]

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.[7] 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.
As of October 11, 2025, the National Disaster Risk Reduction and Management Council (NDRRMC) reported that 722,919 people were affected and over 23,562 others were displaced. Additionally, 79,959 houses were damaged, of which 5,343 were destroyed.[33][35] The Visayan Electric Company reported power outages in some areas.[36] 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.[37] Twenty-seven power stations failed, resulting in power outages that affected 819,843 consumers across 309 municipalities.[38] Business operations in the Philippines were disrupted when the Cebu IT Park was evacuated.[39] Power outages also occurred in Iloilo City.[40]

Multiple sinkholes appeared in Daanbantayan and Medellin following the earthquake.[41][42] At least 100 sinkholes were discovered in San Remigio alone.
