Debris Avalanche

Rapidly moving masses of rock debris produced by large-scale landslides and rockfalls that travel many kilometers from their source, burying everything in their path. They can be triggered by eruptions, volcanic earthquakes, or regional earthquakes, or they may occur without an obvious cause.
