Jim Sterling didn’t know what had hit his 156-year-old antebellum home when an earthquake struck Alabama’s old plantation region early one morning last November. Startled, he grabbed a gun and ran outdoors.
In the pre-dawn chill, Sterling said he found an odd scene: horses were galloping, cows mooing and dogs barking.
“I heard a boom and felt the shaking,” Sterling said. “It really upset me.”
More than a dozen weak earthquakes have followed in the seven months since in west Alabama’s rural Greene County, and geologists are trying to figure out what is causing the seismic swarm in an area of the south more prone to tornadoes than earthquakes.
