Residents of Shelby County were awakened Thursday morning by an earthquake in the same vicinity of last week's quake.
Shelby County Emergency Management Coordinator Danny Lawrence said the quake shook the fire station where he was on duty and there was minor damage around the county, but no major damage or serious injuries were reported.
A statement from the Shelby County Sheriff’s Office stated an elderly woman was injured when she was thrown from her bed, but the statement said those injuries were minor.
Sheriff’s officials said the 4.3-magnitude quake occurred about three miles east of Timpson and lasted about 15 seconds.
He explained that swarms of small quakes in areas not usually affected by earthquakes are not unusual.
Bellini said he did not expect any quakes to grow in strength and he could not say whether fracking, a process used to extract oil and gas from the earth, played any role in the two quakes.
It's called the Mount Enterprise Fault.
The fault is active and delivers low-level quakes, such as Thursday's, fairly regularly. He said the last one he could recall struck the area around 1994 and measured between 3.5 and 4 on the United States Geological Survey's equipment.
Lawrence said USGS data shows there was a strong quake in the area in 1957 and then every few years, there are small quakes that most people never realize have occurred.
“These past two quakes have everyone a little uneasy right now,” he said. “If we have another then it will really get people upset, because this is not something we are used to seeing like the folks out in California.”
