The New Madrid Seismic Zone in northeastern Arkansas has become very active of late. The map on the left shows 226 quakes that have struck this area over the past 4 weeks. Below the maps is a specific list when these quakes occurred. Their magnitudes are indicated in the legend at the bottom of the left map. The map on the right shows the location of the NMSZ, circled in red, which cuts into the northeast quadrant of Arkansas.
