Landslide

Landslide Summary

Landslides, including rockfall and other debris flow, as a natural hazard exist in every state in the U.S., and can be a serious geologic hazard. They sometimes present a threat to human life, but most often result in a disruption of everyday services, including emergency response capabilities. Landslides can and do block transportation routes, dam creeks, and drainage and contaminate water supplies. When these hazards affect transportation routes they are frequently expensive to clean up and can have a significant economic impact on the county. The Federal Emergency Management Agency (FEMA) describes debris flows, sometimes referred to as mudslides, mudflows, lahar, or debris avalanches, as common types of fast-moving landslides. These flows most frequently occur during or after periods of intense rainfall or rapid snowmelt and have been linked to forest management practices, soil types, and the underlying soil structure. 

Landslide History and Location in Morrow County 

Morrow County Public Works Department clears the County roads from landslide debris in the rugged terrain of the South County areas. These landslides often occur after rain events and are generally not significant enough to block traffic, although along Rhea Creek and Willow Creek Roads landslide events have been most numerous and have been known to temporarily block traffic.
