Abstract
Landslides are a complex geologic hazard that occurs worldwide, impacting lives, infrastructure, and property. The Big Sandy Area Development District, Kentucky incurs high landslide activity impacting several municipalities. This hazard mitigation planning project includes landslide susceptibility and risk assessments for the Big Sandy Area Development District. We based the landslide susceptibility model on statistics of hillslope morphological features such as slope, curvature, roughness, aspect, and elevation. Using a dual machine learning approach, we modeled the probability of landslide occurrence, defined as an area that is occupied, or might be occupied in the future, by a landslide. We also developed the risk assessment using a static, socioeconomic approach that includes landslide effects on population, roads, railroads, buildings, and land class. We incorporated hazard (susceptibility results), vulnerability, and consequences to produce each risk map. The plan contains useful information needed for each community in the region to develop mitigation strategies that will support building and infrastructure needs, land use planning, event awareness , response, and recovery actions for communities.
