Earthquakes in Arkansas

Northeastern Arkansas lies within the New Madrid Seismic Zone, the most active earthquake region in the central U.S., and central Arkansas saw an induced swarm near Guy and Greenbrier (2010–11) tied to oil-and-gas wastewater injection. Most events are small, but the New Madrid system is capable of major earthquakes, and the soft Mississippi Valley soils amplify shaking.
