At 21:59 local time on 30 September 2025 (13:59 UTC), an Mw 6.9 earthquake ruptured the seabed of Bogo Bay, just north-east of Bogo City at the northern tip of Cebu in the central Philippines. The shaking was shallow (about 10 km deep), close inshore and struck at night, when people were already in bed; instrumental readings reached a violent MMI 8.94, and PHIVOLCS assigned a maximum local intensity of PEIS VII (Destructive). Houses, churches and school buildings collapsed across Bogo, San Remigio, Medellin, Daanbantayan and Tabuelan; 79 people were confirmed dead and 599 injured, with around 160,000 houses damaged and more than 7,000 destroyed. It was the strongest earthquake ever recorded in northern Cebu and the deadliest to hit the Philippines since the 2013 Bohol Mw 7.2.
The fault behind it, now named the Bogo Bay Fault, was not on any hazard map before the event: an offshore, right-lateral strike-slip structure that PHIVOLCS says had shown no significant movement in more than 400 years, only pinned down afterwards from the aftershock cloud and a drone-mapped surface rupture. By raw size the quake barely registers, , yet it produced one of the Philippines' deadliest disasters in over a decade because the rupture was shallow, close to town, at night, over weak building stock. The Philippines carries one of the world's widest catastrophe protection gaps, insurance penetration just and fewer than one in five households covered, so the transfer to insurance markets will be : a new domestic pool, the , had launched only and covers earthquake risk, but the binding constraint remains how few homes carry any cover at all.
