Landslides Risk in Nebraska — Level 1 of 5

Nebraska has a low risk of landslides, rated Level 1 of 5, due to its generally flat terrain. However, localized slope failures can occur along river bluffs, especially in areas with loess soils or after heavy rainfall. Homeowners should understand the small but real risk and take simple precautions to protect their property.

Landslide Characteristics in Nebraska

Nebraska is not considered a high-risk state for landslides. The U.S. Geological Survey (USGS) Landslide Hazards Program indicates that the state’s generally flat to gently rolling terrain is not prone to widespread slope failures. Most landslide activity in Nebraska is limited to specific locations where the topography and soil conditions combine to create unstable slopes.

The most landslide-prone areas in Nebraska are the steep bluffs and valleys along the Missouri River and its major tributaries, such as the Platte, Niobrara, and Republican Rivers. These areas can have steep slopes composed of loess—a wind-deposited silt that is highly erodible and can be unstable when saturated. Riverbank erosion and undercutting by flowing water can also trigger small slumps or mudslides, particularly after periods of heavy rain or rapid snowmelt.

In western Nebraska, the badlands and buttes of the Panhandle region can experience localized rockfalls or soil slides, especially where the underlying bedrock is weak or fractured. These events are usually small in scale and rarely affect populated areas, but they can damage roads, fences, or outbuildings.

Nebraska’s climate contributes to a lower landslide frequency than in mountainous states. Most rainfall occurs as moderate soaks rather than intense deluges, which reduces the likelihood of sudden slope saturation. However, flash flooding events, which have occurred in parts of the state, can still increase the risk of slope failure in vulnerable spots.

The Nebraska Emergency Management Agency (NEMA) provides guidance on natural hazards, and it classifies landslides as a low-probability but possible hazard. They encourage local governments and residents to be aware of any slopes near their property, especially if there are signs of existing movement such as cracks in the ground or tilted trees.

How It Affects Homes

For most Nebraska homeowners, the risk of a landslide damaging their home is very low. However, homes built on or near river bluffs, steep embankments, or eroding riverbanks can face a real threat. Landslide damage can range from minor soil movement cracking foundations or driveways to major slope failures that shift the structure off its foundation or cause complete destruction.

One of the most important insurance considerations is that standard homeowners insurance policies typically do not cover landslides, mudslides, or earth movement. If a landslide is triggered by a flood, flood insurance may cover some resulting damage, but not always. NEMA advises homeowners to review their policies and, if they live in a high-risk area, consider purchasing a separate earth movement policy or a flood insurance policy through the National Flood Insurance Program (NFIP).

Even in low-risk states, the financial impact of a landslide can be severe. Repairing a foundation or stabilizing a slope can cost tens of thousands of dollars, and federal disaster assistance is rarely available for isolated landslides unless the event is declared a major disaster. This makes proactive prevention the most cost-effective approach.

Additionally, landslides can affect more than just the house itself. They can damage septic systems, wells, underground utilities, and access roads. If you live near a slope, it is wise to monitor for warning signs such as new cracks in the soil, sticking doors or windows, or water pooling in areas that were previously dry.

How to Prepare Your Home

Even though the risk is low, you can take simple steps to reduce the likelihood of landslide damage. Here are practical measures recommended by Ready.gov and the USGS Landslide Hazards Program:

Inspect your property for signs of slope instability, such as cracks in the ground, bulges at the base of a slope, or tilted trees, fences, or utility poles.
Manage drainage – Direct rainwater away from slopes using gutters, downspouts, and French drains. Avoid letting water pool near the top of a slope.
Maintain vegetation – Plant deep-rooted grasses, shrubs, or trees on slopes to help stabilize the soil. Avoid removing existing vegetation, especially on steeper areas.
Build retaining walls if you have a slope on your property that is eroding or shifting. Consult a geotechnical engineer or local building official for proper design.
Do not overwater – Avoid irrigating the top of a slope, as excess water can saturate the soil and trigger a failure.
Minimize excavation – If you need to dig into a slope for a basement or foundation, hire a professional and use proper shoring techniques.
Monitor riverbanks – If your home is near a river, watch for rapid bank erosion during high water or prolonged rain events.
Secure outdoor items – If a small slide occurs, propane tanks, lawn furniture, and other loose items can be damaged or become hazardous.
Develop an emergency plan – Know how to evacuate quickly if a landslide threatens your home. Practice the plan with your family.

Frequently Asked Questions

What should I do if I think my home is on a landslide-prone slope?

If you notice signs of ground movement, contact the Nebraska Emergency Management Agency or your county emergency manager. They can recommend a professional geotechnical evaluation. Also, inspect your insurance policy to see if you have earth movement coverage, and consider adding it if you live in a high-risk area.

Can landslides occur in Nebraska without heavy rain?

Yes, landslides can also be triggered by rapid snowmelt, river erosion, earthquakes (very rare in Nebraska), or human activity such as excavation, grading, or improper drainage. Even a small disturbance can cause a slope to fail if the right conditions exist.

Are landslides covered by flood insurance in Nebraska?

Flood insurance may cover damage caused by a landslide if the landslide was directly triggered by a flood. However, standard flood insurance does not cover general earth movement. It is essential to ask your insurance provider whether your specific policy includes mudslide or mudflow coverage, and if not, consider purchasing a separate earth movement endorsement.
