On April 11, 2021 an avalanche with an initial size of around 14000 m3 (3.3 106 kg) was artificially released.
An estimated additional mass of 4.5 106 kg was entrained by the avalanche along the track. After approximately 50 s the avalanche reached the catching dam in the runout zone, making the avalanche one of the fastest to be observed at the test site.
The avalanche may be classified as a relative size R4. In addition, observations from eight further avalanches were obtained during the 2020/2021 season.
We present some preliminarily results gained during those events. Further, we try to link the results to more recent theoretical work and we discuss implications to hazard mapping procedures.
