Rapid movement can be dangerous, such as during debris flows. Areas with steep topography and rapid rainfall, such as the California coast, Rocky Mountain Region, and Pacific Northwest, are particularly susceptible to hazardous mass-wasting events.

Why is Southern California prone to landslides?

Southern California is tectonically active and geologically complex, and this complexity strongly controls when and where landslides occur throughout the region.
