Resolved, and now being watched so it does not simply happen again.
A cover-collapse sinkhole was first reported at 4:45 a.m. on 20 August 2026 in Sitio Indilicio, Purok Libog 1, Barangay Guadalupe, Bogo City. MGB-7 assessed it on 22 and 23 August, measuring it at about 15 by 25 meters with an estimated cavity depth of around 15 meters, and found it had widened by roughly two meters with continuing rim collapses, rumbling sounds and groundwater flow; the nearest house was 18 meters from the rim. In a 24 August advisory the bureau classified the site a high-risk ground collapse area and recommended a 20-meter no-entry zone and a 50-meter controlled-access zone, with pre-emptive evacuation during heavy rain.
