Researchers at the Kentucky Geological Survey say maps published by the U.S. Geological Survey overstate the earthquake threat in Western Kentucky and the surrounding region.
KGS researchers at the University of Kentucky have been working for a decade to have the maps changed to reduce the estimated threat level. The USGS uses a probabilistic method to determine the earthquake hazard level, a method KGS researchers say is flawed.
“This method, mathematically, is not correct,” said Zhenming Wang, head of the KGS Geologic Hazards Section. “The national hazard maps are not scientifically sound; that’s why there is a problem.”
