Location of AEM lines across Crowleys Ridge This dataset provides location information for the airborne electromagnetic (AEM) lines across Crowleys Ridge in the New Madrid seismic zone, central US. The AEM data are interpreted and discussed in the associated publication Categories: Data; Tags: Arkansas, Central United States, GHSC, Mississippi Alluvial Plain, New Madrid Seismic Zone, All tags...

We mapped newly-identified coseismic ridge-spreading features, or sackungen, in the bluffs east of the Mississippi River in western Tennessee. We use this mapping dataset in an accompanying manuscript to show that sackungen form during earthquakes on the Reelfoot fault and may fail in preferred orientations. Ultimately, these data can be used to infer fault source and mechanism and improve the paleoseismic record used in hazard models.

The release includes location information for seismic reflection and airborne electromagnetic (AEM) data over Crowleys Ridge, a table of topographic metrics derived from analysis of the 10m National Elevation Dataset (NED) digital elevation model (DEM), a shapefile of scarps mapped on a 1m bare-earth lidar DEM, and a shapefile of a revised New Madrid seismic zone fault network interpretation. These datasets are associated with the publication: Thompson Jobe, J.A., Gold, R.D., Briggs, R.W., Williams, R.A., Stephenson, W.J., Delano, J.E., Shah, A.K., Minsley, B.J.,...
