1. Snow Cornices: Avalanches can form snow cornices, which are overhanging masses of snow that extend out from a ridge or slope. These cornices can collapse under their own weight or under the weight of additional snow, triggering an avalanche.
2. Crevasses: Avalanches can also create crevasses, which are deep cracks or gaps in the snowpack. Crevasses can be dangerous for skiers and snowboarders, as they can cause them to fall and become trapped.
3. Seracs: Avalanches can also form seracs, which are large blocks of ice that break away from a glacier. Seracs can be extremely hazardous, as they can fall on people or buildings below.
4. Rockfalls and Landslides: Avalanches can also trigger rockfalls and landslides, as the force of the avalanche can dislodge rocks and soil. These rockfalls and landslides can damage infrastructure and cause injuries or fatalities.
5. Debris Flows: Avalanches can also generate debris flows, which are fast-moving mixtures of snow, ice, water, and debris. Debris flows can cause significant damage to infrastructure, including roads, bridges, and buildings.
