When a snow slope fails, the impact of the avalanche depends on such variables as the length, shape, and roughness of the avalanche path. If disaster strikes, buried victims must be rescued quickly, since the chance of survival decreases sharply with time. Methods of avalanche control include artificial release by explosives, defense structures, public warnings, and land-use legislation.
