Map showing inventory and regional susceptibility for Holocene debris flows and related fast moving landslides in the conterminous United States: vector data

Debris flows, debris avalanches, mud flows and lahars are
fast-moving landslides that occur in a wide variety of environments
throughout the world. They are particularly dangerous to life and
property because they move quickly, destroy objects in their paths,
and can strike with little warning. The purpose of this map is to
show where debris flows have occurred in the conterminous United
States and where these slope movements might be expected in the
future.
