Yes they can cause avalanches if they are high up in a mountain were there is snow, rocks, or loss soil.
Most likely no cause there trees
no
Global warming is unlikely to cause avalanches directly. They are usually caused by runoff from heavy rain and intense storms. Global warming is expected to cause more intense storms and could therefore be an indirect cause of avalanches.
Avalanches are caused when a big impact of noise strikes. This is because sound vibrates objects and therefore vibrates mounds of snow, causing them to tumble down.
Avalanches can't really be measured, except by the damage they cause. They are observed by the people that are lucky (or unlucky) enough to see them.
To predict an avalanche, scientists use a large cannon that can lock on to exact cordinants of avalanche paths and cause smaller avalanches before the big ones happen. They can also dig a pit and run various experiments. There is a video on the discovery site called our raging planet: Avalanches that will give you all this information and more.
Slight tectonic plate movements
they cause them safely, before an innocent snow sportist accidently starts it.
yes they do because it will make the place safer
No. Loud noises do not actually set off avalanches believe it or not. If you don't believe me look up "Avalanches 101" on youtube.com or National Geographic.
When the sound waves of pressure move across the land it can cause erosions, leading to avalanches. Or as they both shake the earth nearby, causing an avalanch.
The animals in the path of the avalanche are likely to be killed by it.
