Here in Troms county it's been raining since friday. With the snow allready on the ground, and expected snowfall and later rain again, plus a small storm coming in conditions are perfect for avalanches. It's all over the news, but since this is the first day of the kids winter holliday, I suspect that right now there is an idiot up in the hills crossing an avalanche prone area....will let you know when the news ticks in...
Anyway here are some avalanche facts:
• An average of 5 people are killed by avalanches every year in Norway. A house offers no protection against an avalanche
• 90% of all hikers taken by an avalanche set them off themselves
• The majority is hit by an avalanche when the Avalanche danger is medium
• An avalanche may move as fast as 50 meters a second.
• An avalanch can reach more than 1 km
• An avalanche can contain more than 100000 cubic mters of snow.
• one cubic meter of snow may weigh 700 kilos.
• An avalanche may induce a pressure of 40 ton per square meter
• A house wall can withstand a pressure of 200 kilos per square meter
* Within 30-45 minutes most people taken by an avalanche will die, if not rescued.
Maybe the Rescue volunteers on here will like to see this report and get something out of it. It's from last years big avalanche when 6 tourists got hit. 5 of them died. The survivor was buried by the avalanche but had his head above snow.
