DEARMAN, AR - A mild earthquake rattled a portion of northeast Arkansas in a region that has seen a number of tremors this year.
Last night's quake, of magnitude 3.0, was centered two-thirds of a mile west of Dearman in Mississippi County.
The area is in the New Madrid Seismic Zone. Between May and late July, there were six earthquakes of magnitude two or greater in the southern part of the zone, which includes Arkansas. Four earthquakes near magnitude four have occured since February.
Researchers say that, there are 150-200 earthquakes in the state each year.
A quake of magnitude 2.5 to 3 is the smallest generally felt by people.
