Overview
- The 4 km rupture and roughly 50 m escarpment continue to retreat toward the town, displacing about 1,300–1,500 people as the red zone is expected to expand.
- The Basin Authority says a decree will enlarge the mapped risk area by around 25 km² with an absolute construction ban, extending to areas downslope.
- Civil Protection has initiated a formal hydrogeological risk assessment with geognostic studies and instrumented monitoring, as prosecutors probe suspected negligent disaster and an administrative inquiry is proposed.
- Engineers call for immediate stormwater interception and a package of works estimated near €30 million—including monitoring, deep drainage wells and earth-reinforcement—warning many homes are uninhabitable and partial relocation is likely.
- Officials estimate about 350 million cubic metres have moved, exceeding Vajont’s volume, with saturated sands sliding on clay seen as the primary driver and other hypotheses, such as methane pockets, under examination.
