The present mortality as a result of snow avalanches exceeds the average mortality caused by earthquakes as well as all other forms of slope failure combined.

However, programs for snow avalanche hazard mitigation in other countries are far ahead ... Read moreof those in the United States.

The book identifies several steps that should be taken by the United States in order to establish guidelines for research, technology transfer, and avalanche legislation and zoning.
