Avalanches

The video explains how avalanches form in mountainous areas due to weak snow layers and heavy snowfall. It distinguishes between slab and powder avalanches based on snow type. Monitoring weather conditions helps predict avalanches, while safety measures like barriers and controlled avalanches aim to minimize damage. Despite precautions, most avalanches are accidentally triggered by humans, especially skiers and snowboarders.
