Landslides Risk by US State — Maps, Data & Home Preparedness | HomeRiskMap

Landslides and mudflows occur in all 50 states, often triggered by heavy rain, wildfires or earthquakes.

How to prepare your home

Learn whether your area has a history of landslides or debris flows.
Watch for warning signs: new cracks, tilting trees, doors that suddenly stick.
Plant ground cover on slopes and build retaining walls where appropriate.
Be especially alert after wildfires — burned slopes shed water fast.
During intense storms, stay awake and ready to evacuate if in a risk zone.
