Early on 14 April 2024, more than a million m³ of rock and ice broke from the north face of Piz Scerscen (3,971 m) in the Bernina range. The mass fell onto the Tschierva Glacier and ran about 5 km down the valley.
No one was hurt. The event was recorded by seismometers across the Alps. According to the WSL it was the largest Swiss rock avalanche by volume since Randa in 1991.
