## In brief

- On May 12, 2023, authorities ordered the evacuation of the village of Brienz/Brinzauls in the canton of Grisons because a rapid slide of the slope above it appeared imminent.
- The rockslide did not occur until the night of June 15–16, 2023, several weeks after the evacuation order.
- The analysis attributes the delay to an old talus slope.

## Why it matters

The finding suggests that pre-existing slope features such as old talus deposits can change when a large rockslide actually happens, which matters for hazard forecasting and evacuation timing.

## Timeline

- 2023-05-12: Authorities ordered evacuation of Brienz/Brinzauls
- 2023-06-15: Rockslide occurred during the night of June 15–16
