Avalanche control system and method using one or more chambers in an avalanche-prone area to control the removal of snow or other material which might avalanche. The system includes a plurality of spaced housings made of a solid material like “shock-crete” and an asymmetric flywheel coupled to a motor which is controlled by a signal to warm up and turn on at a desired time to vibrate the housing and cause removal of loose snow or other material and/or the compacting of that material to make avalanching less likely.
