· Deforestation can contribute to avalanche formation. Hence, rainwater cannot be trapped and held. This removes the natural barrier to avalanches and landslides.
· When mountainous areas are cleared and developed to tourist resorts, people start visiting it. The various activities of people wear away the vegetation. Thus, like deforestation, the natural barrier to avalanches is removed
Other human causes are contruction, mining and global warming. Road construction steepens the slopes, while quarrying and mining causes big holes to be dug into the ground, making the land unstable and may collapse. Global warming causes changes in weather patterns. It can cause snow to melt when it should not, and thus, increasing the risk of an avala

What causes the high speeds of avalanches?
the wind!!
When do you get avalanches?
Avalanches are most likely to occur in the alpine regions of France, Switzerland and Austria. However avalanches can occur on any steep slope, considering the factors. Within the U.S, Alaska, Colorado and Utah are the states that avalanches occur most often.
How often do avalanches occur?
20 or 30 times a year 20,000 each year (this is right ha ha)

What causes slab avalanches?

Why are more areas prone to have avalanches?
The Rocky Mountains are very steep, and avalanches are common as a result.
Are Avalanches are common in winter in the Alpine mountain system?
yes. (:
What causes slab avalanches?
a certain degree of slope and then some special weather conditions.
What are the most unlikely human causes of avalanches?
Usually accidental avalanches are caused when people are mountain climbing or skiing, and they don't check the conditions of the mountain prior to when they are doing it, this often results in them starting an avalanche, simply by passing over some loose packed snow.
What is some common natural disasters in the Rocky Mountains?
Blizzards and avalanches
