Selected known landslides in Kentucky. Although exact costs are not documented,
landslides affect roads,
pipelines, private residences,
and other parts of
the built environment. Direct costs such as repair and maintenance
exceed $10 million
and indirect costs may exceed direct costs but are difficult to quantify.
With a good landslide
citizens can begin to understand landslides processes,
assess risk, and prevent damage from the threats

Landslide Projects and Related Research
- Landslide Inventory: This ongoing project provides a comprehensive framework and understanding of landslide data for Kentucky. There is a wealth of landslide information, such as hard-copy maps, state agency reports, and digital databases, which originate from many different sources. The main goal is to compile this information into a standardized database and use the most important data to understand landslide hazards in Kentucky. Landslide locations from the inventory can be viewed in the Landslide Information Map.
To read more on the design and application of the KGS landslide inventory see KGS Information Circular 31
The KGS also cooperates with the U.S. Geological Survey and other state surveys to promote the importance of landslide inventory projects. Read more here: Landslide Inventory Project.
- Landslide Information Map: Online map that shows known landslide hazards and areas susceptible to landslides. Landslide locations come from KGS research, published maps, state and local government agencies, the pubic, and the media. The purpose of the map is to provide an overall view of landslide hazards across the state.
- Landslide Monitoring and Characterization
- Light Detection and Ranging (LiDAR)
- Search KYTC Geotechnical Projects (Be sure to choose Project Type: Landslides.)
- Quaternary Geologic Mapping: KGS geologists, through the USGS STATEMAP program are mapping Quaternary deposits along and adjacent to the Ohio River, in parts of Eastern Kentucky, and in parts of Northern Kentucky to improve existing geologic mapping in the area. These sediments were originally generalized into a small number of mapping units during the geologic quadrangle (GQ) mapping program. Because of their importance for land-use development, geotechnical planning, landslide hazards, groundwater supply, and their sensitivity to ground shaking during earthquakes, providing high quality geologic maps of these areas is a priority. KGS personnel are working with scientists from other local, state, and federal agencies to complete this mapping and share results. GIS products will include new digital, vector geologic quadrangle data sets for these areas. Contact Drew Andrews for more information.
Large, rotational slump along old KY 10. Numerous landslides
caused a re-routing of the road and the use of newer KY 9 (AA Highway).
Landslides like these cost the state millions of dollars each year to repair.
