Abstract The Mississippi Alluvial Plain hosts one of the most prolific shallow aquifer systems in United States but is experiencing chronic groundwater decline. Reelfoot rift and New Madrid seismic zone underlie region represent an important poorly understood hazard. Despite its societal economic importance, subsurface architecture has not been mapped with spatial resolution needed for effective management. Here, we present airborne electromagnetic, magnetic, radiometric observations,...
<p>Critical groundwater resources and hidden seismic hazards underly much of the Mississippi Alluvial Plain. Spanning nearly 100,000 square kilometers across seven states, this region hosts one most prolific shallow aquifer systems in United States that supports a $12 billion agricultural economy amidst chronic decline. Further, underlying fault structures Reelfoot Rift New Madrid Seismic Zone represent an important poorly understood hazard with complex pattern historical...
