How long will earthquake aftershocks last?
The National Earthquake Information Center has reported seven aftershocks since an earthquake shook the Tennessee Valley early Wednesday morning.
"The after-effects of this particular event are probably, largely exhausted. Probably, but again, it's kind of hard to say, "Jonathan Mies, a UTC geology professor, explained.
Mies said it's hard to predict the earth's movements, especially after an earthquake.
Since Wednesday’s magnitude 4.4 earthquake, several aftershocks have been reported. However, it's not very likely many people felt them or will feel any more of them.
"They tend to be small,” Mies explained. “But someone that's located very close to the epicenter of those aftershocks could conceivably feel them."

Some people felt the first aftershock. It was a magnitude 3.0. After that, most were roughly a magnitude two or less.
A map shows the location of each reported aftershock. The aftershocks appear to form a pattern, a line likely following the fault line.
Mies said we probably won't feel any more aftershocks related to this event, but earthquakes can happen at any time and are difficult to predict.
"For that reason, it's worthwhile being aware of it, being concerned about it, being prepared for it as best you can," Mies added.
