An avalanche is a rapid flow of snow down a sloping surface. It occurs when a layer of snow collapses and slides downhill, often triggered by natural events like new snowfall, rapid temperature changes, or human activities such as skiing and snowboarding. Avalanches can be incredibly dangerous, capable of burying people and structures in their path. They vary in size and intensity, from small slides to massive snow masses that can sweep away trees and boulders. Effective avalanche forecasting and safety measures are essential to minimize risks in mountainous regions.
