Authorities in New Zealand deliberately triggered an avalanche over the weekend in Milford Sound to prevent a potential disaster.

Transportation officials used explosives to release massive amounts of snow in a controlled operation after heavy snowfall had created a dangerous risk of natural avalanches. The road below was temporarily closed to ensure public safety during the procedure.

The controlled avalanche was carried out successfully without incident, clearing unstable snow and reducing the risk of an unexpected slide that could have endangered travelers and infrastructure.

Officials said the measure was necessary to keep Milford Sound accessible while maintaining safety for commuters and tourists in one of the country’s most visited natural destinations.
