As every year, the municipality of Chamonix has published the “Dicrim” - the Municipal Information Document on Major risks. It has about 15 pages and it informs the population about the dangers (natural and technological risks) in Chamonix and how to prevent them, if possible.
Because it is a mountain area, Chamonix Valley is prone to avalanches. “There are 124 avalanche corridors that can reach the valley and 80 that can reach roads or homes”, as Jean-Louis Verdier, deputy safety officer of Chamonix commune.
The hamlets of Tour, Montroc, Planet, Biollay, Nants, Moussoux, Gaillands and Taconnaz are particularly known for their avalanche risks. Despite all the protective structures, some areas may be evacuated. The population will then be organised in groups and places of accommodation will be established by the town hall.
