The rockslide and glacier collapse in Blatten was the fourth largest rockslide ever observed in Switzerland and, due to the combination of several collapse processes, highly complex, if not unique.

However, the data collected during this event can certainly be described as unique. It is no exaggeration to say that no similar event has ever been observed and monitored so closely. This presents a unique opportunity to analyze the event, learn from it, and gain a better understanding of the relevant processes. The canton of Valais therefore wishes to make the data collected during the event available to the scientific community.

In addition to an overview of this data, we will present a brief chronology of the event. We will also focus on the practical questions that remain open to us, which we hope to answer together with the scientific community.
