Avalanches can be very dangerous, but sometimes it is necessary to create controlled avalanches to protect towns and people. Here are several videos demonstrating different ways people create avalanches:
- Alaska State Troopers use a cannon to trigger an avalanche.
- Avalanche control experts drop explosives from a helicopter to create an avalanche.
- Trained climbers knock down loose rocks before they become dangerous for cars driving below.
Create an Avalanche: Instructions to make a simple and safe avalanche from the US Forest Service.
