They are used by people and infrastructure that are exposed to avalanche terrain. This usually involves alpine touring or snowmobiling, but in certain areas, e.g. Norway, a lot of roads and other infrastructure has been built right below dangerous slopes. They are used to evaluate what risks and consequences that are involved in certain route choices. Should you choose to go up on a north or south facing slope today? Do we need to fire these gas cannons and trigger an avalanche today to avoid having an avalanche reach the rail tracks tomorrow?
