Many earthquakes in northeastern Arkansas and nearby portions of Missouri and Tennessee occur in or around the New Madrid Seismic Zone.
The seismic zone is one of the most recognized earthquake regions in the central United States.
It includes portions of northeastern Arkansas, southeastern Missouri, western Tennessee and western Kentucky.
The region is known for a series of powerful earthquakes in 1811 and 1812.
Although most earthquakes recorded in the region today are relatively small, emergency management officials continue encouraging residents to be prepared for stronger earthquakes.
The number of small earthquakes alone does not establish that a major earthquake is imminent.
