The Shijiazhuang City in Hebei Province lies at the junction between the Taihangshan uplift in the west and the Jizhong depression of North China in the east, abutting the front-range fault zone of the Taihangshan in the west.The Xingtai M7.2 earthquake of March 1966 occurred southeast to this area. In MT data processing, in addition to the remote reference and robust techniques, the multi-point and multifrequency tensor decomposition was employed to determine the regional electric strike, and the NLCG 2D inversion was performed on TE and TM data. The result shows that a combination of an eastdipping low-angle normal fault in the shallow subsurface and a steep electric boundary at depth characterizes the deep structure beneath the study area. The electric structures in the shallow crust (above 10km) and deep crust (below 10km) seem to be independent.
