By Friday morning 365 people had been forced to leave their homes because of Wednesday's landslide in the Swiss village of Blatten. The geological situation is still too dangerous for direct operations. The lake behind the debris is under constant observation.

The River Lonza and the reservoir in Ferden are also being continuously monitored, the Valais State Chancellery said. The canton has installed measuring devices for this purpose. The landslide mass, which is several dozen metres high and around two kilometres long, is blocking the Lonza, which is why a lake has formed.

The canton put the total volume of ice and rock deposits on the valley floor at ten million cubic metres. Over the course of Friday morning, the lake level approached the upper edge of the debris mass. The authorities expected the dammed lake to overflow during the course of the day. In view of this, they increased the storage capacity of the Ferden reservoir.

Due to the risks and geological instability, no operations are currently possible in the disaster area, the State Chancellery added. The army is on standby with water pumps, excavators, other heavy clearing equipment and lighting material. Experts from specialised engineering firms, 50 civil defence personnel and around 100 firefighters are also deployed.

The cantonal road from Goppenstein to Blatten remains closed. There are exceptions for local residents and emergency vehicles. The cantonal management body is constantly analysing the situation and is in contact with the regional management teams.
