What is the highest speed of an avalanche?

Avalanches can reach speeds of up to 80 miles per hour (approximately 130 kilometers per hour) in their initial stages. However, some exceptionally fast avalanches can exceed speeds of 100 miles per hour (160 kilometers per hour) in certain conditions. The speed can vary based on factors like the type of snow, terrain, and slope angle. These rapid movements make avalanches extremely dangerous.
