After mudslide in South Tyrol: Around 120 people evacuated in the Ahrntal valley

Situation in Luttach

The operation was triggered by a mudslide that swept debris and mud into the valley in the area of the municipality of St. Johann im Ahrntal. Mudflows can occur after heavy rainfall or during rapid snowmelt and can cut entire settlements off from the outside world.

Luttach, a district of St. Johann, lies at the confluence of the Rotbach and Gisse, two tributary streams of the Ahr. The municipal area extends into the farthest part of the Ahrntal valley and is known for its location in an alpine area prone to flooding.

Background: Where is the Ahrntal valley?

The emergency services initially focused on accommodating and caring for those affected. How long the people had to remain in the multi-purpose hall and whether there were any injuries was not known in detail at first.

After mudslides, the responsible authorities generally have to inspect the affected terrain for further risks before residents are allowed to return to their homes. Cleanup work and the restoration of infrastructure can also take several days.

Why the Ahrntal valley is particularly at risk

The Ahrntal valley is one of the most densely populated side valleys of South Tyrol and, due to its steep slopes and narrow valley locations, is particularly susceptible to mudslides and flooding. In previous years as well, severe weather in the region had led to closures and evacuations.

Given the experience of past events, the weather situation in South Tyrol remains sensitive: heavy rain, thunderstorms, and prolonged precipitation can destabilize the slopes and increase the risk of further mudflows.
