Which states have the highest landslides risk?

Alaska currently ranks at the top of this list (High). Rankings are statewide averages — a county can sit well above or below that score.

Does homeowners insurance cover landslides?

Landslides and mudflows often fall in a coverage gap: excluded from homeowners, flood and earthquake alike unless you buy specialty coverage.

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

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.
