Features steep mountain have a major impact on avalanche. In the mountains, 30 ° -50 ° degree slope covered most of the avalanche.

If the mountain side is a cut that is much greater risk that it will avalanche

 

Avalanche fall when overdraft warming will be stronger than the cohesive power of snow epithelium. Therefore, it is clear that to AVALANCHE HAZARD be with that at all against snjóþekjan need to be well cohesive and no weak songs found.

Avalanche is divided into two categories Available Avalanche and prefabricated avalanche.

 

The prefabricated run crawls snjóþekjan of place in well-preserved rafts of aggregation. Large areas can go off at once, and moved a tremendous amount of snow. Often fraction edge at source flood sharp and examples are in Iceland for up to 8 meters high brotsár.

 

Iceland are prefabricated floods more common than loose avalanches. Avalanche have different flow rate and dry flood flow faster than the watery floods. Powerful kófhlaupin can reach enormous speeds. Ahead of such flooding is powerful pressure wave that can splundrað the road will be, for example, houses and cars.

 

Avalanche are the natural disasters that have caused the most damage in this country.

 If the substrate is covered with ice, the ice forms a good surface flow and falling snow on the ice can be a high risk of exposure.

 

It is most common in this country snowing start in cold weather, but then gets warmer and the snow begins to gain weight. Wet and heavy snow sits on top of a lighter and weak snow. If this happens the result is often that the avalanche fall.
