I don’t speak Russian, or whatever language is being spoken in this video, but I’m pretty sure that at some point there are a couple of people saying, “Oh sh*t!” as things get interesting.

Here’s the Google translation of what the original poster put for the video description:
02/16/2011 Kabardino-Balkaria, a village Terskol firing avalanche sites. Russia, Republic of Kabardino-Balkaria, Terskol.
