The geological surveys of Iowa, Nebraska, Kansas, and Oklahoma conducted a 4- to 6-year investigation of the seismicity and tectonic relationships of the Nemaha Uplift and associated geologic features in the Midcontinent. Regional geological, gravity, aeromagnetic, seismological, and topographic information were compiled on 1:1,000,000-scale base maps. The following maps were prepared: (1) relief, (2) earthquake epicenter and station location, (3) lineament, (4) geologic bedrock, (5) structure contour (base of Kansas City Group or older Pennsylvanian rock units), (6) Precambrian configuration, (7) Bouguer gravity anomaly, (8) aeromagnetic, and (9) Precambrian rock type. One correlation between earthquakes and tectonic structures was made. There appears to be recent as well as historical earthquake activity associated with the Humbolt Fault zone, southeastern Nebraska and northeastern Kansas.
