How To Prevent Avalanches
A way to prevent avalanches is to prevent conditions that lead to avalanches, such as not using explosives on mountains.
How to reduce the effects of avalanches when spotted.
Alert poeple who are in the risk zone and if neccesarry, get them to safety. Move heavy and stable things in the way of the avalanches predicted path to slow it down or block it.
How to prepare ahead of time to make avalanche damage less.
Planting barriers in the way of an avalanche like windmills and walls could slow down or block the avalanche's progress. Bringing awareness to avalanches would also help. Teaching poeple how to recognize the signs of a possible avalanche and how to deal with one would make the damages less. Also, put warning signs to warn people so they're aware.
How to respond during the avalanche.
Try to place as many sparable things you can in the way of the avalanche to slow it down or block it. If you see an avalanche coming, get everyone move to the side as fast as possible, because instinctively, people would run downwards, but that usually doesn't work.
Getting the community back to normal after the disaster
After an avalanche, you should search for missing poeple as soon as possible, it is very possible that they are dead but if they're alive, they won't last long. Otherwise, the costs of avalanches can be tremendous and remaking the community, will be hard, but buildings can be rebuilt. Disaster response groups such as the Red Cross and others will help.
