Summary
Earthquakes pose hazards and risk to the Commonwealth of Kentucky. The seismic hazards and risk vary throughout the state
Western KY, the Jackson Purchase area in particular, has high hazards and risk
Eastern and northeastern KY have low to moderate hazards and risk
Central KY has low hazards and risk
Seismic hazards and risk in Kentucky (CEUS) is certainly lower than those in California
Summary
The local variations in seismic hazards and risk need to be taken into consideration for the hazard mitigation and risk reduction
