This avalanche is from way back when on Mt. Ruapehu, New Zealand. This is a ridiculously enormous class 5 avalanche with the capacity to take out a village.
There is a ski resort on this mountain just out of view to the looker’s left in this video.
Ruapehu is a very sacred mountain to the Maori people and one of the world’s most active volcanoes. It’s the largest active volcano in New Zealand at 9,177-feet above sea level.
