Seconds from disaster S2E2 Alpine tsunami

At the Austrian alpine village of Galtür, snow on the mountains surrounding the village build up. Due to the changing temperature during the month, a strong but brittle layer of ice forms under the snow. On the day of the disaster, the ice layer collapses and the building ice bank slips down the slope and forms a powder avalanche. Two minutes later, it hits Galtur and buries 57 people in the snow, killing 31 of them.
