According the the U.S. Geological Survey (USGS), a preliminary magnitude 4.7 hit 4 miles northeast of Greenbrier just after 11:00 p.m.
It was felt across the state as well as into Missouri and Mississippi. Two aftershocks where reported afterwards, a 3.8 magnitude then a 3.6 magnitude.
So far, there have been no reports of damage or injuries.
"We probably wouldn't see structural damage until a 5 or 5.5," says Bekki White, Director of the Arkansas Geological Survey. "What you're going to see now is pictures sway, things fall off the wall, shaking, maybe some windows break."
The USGS is asking anyone who felt the earthquake to report it at their Did You Feel It? website.
According to White, this 4.7 magnitude quake was felt more prominently than last week's quakes because it was at a more shallow depth. Previous quakes were reported at 6 kilometers while last night's quake was at 3 kilometers.
Scott Ausbrooks with the Arkansas Geological Survey says this is the largest quake we've had outside of the New Madrid Fault System since 1969.
