In previous seismic studies, researchers interpreted pockets of relatively slow seismic velocities in the eastern US as evidence for thin, broken-up lithosphere. But, magnetotelluric imaging supports a thick, coherent lithospheric block. Murphy and Egbert (2019) reconcile these seemingly contradictory datasets.
