Stronger Earthquake in Kentucky is Possible, But When?
Lots of people in Covington and Greater Cincinnati felt the tremors from the 4.3 magnitude earthquake that hit near Whitesburg, Kentucky Saturday afternoon and that has many folks wondering if a larger one is possible:
While more earthquakes in southeast Kentucky will certainly occur someday, state Geologist Jim Cobb says predicting their exact time and place is impossible. Neither Cobb nor his colleagues at the Kentucky Geological Survey were surprised by Saturday’s four-point-three quake. It’s part of a seismic zone in northeastern Tennessee where earthquakes, ranging from “light” to “strong” can occur. During stronger quakes, Cobb said, some older school buildings could be at risk.
“They can be one, two, or even three story buildings. And some of these schools, elementary schools, junior high schools, high schools can be old. Those are the kinds of structures that we worry about,” Cobb said.

Meanwhile, an expert from the University of Kentucky says the quake was not caused by underground mining in eastern Kentucky:
Zhenming Wang, the head of UK's Geologic Hazards Section, says Saturday's quake occurred about 12 miles below the surface, far too deep for underground mining to have been a factor.
Wang says the earthquake occurred near the Eastern Tennessee Seismic Zone, which receives a four-magnitude quake every five to ten years.
