From: Application of electrical resistivity tomography (ERT) for rock mass quality evaluation

Resistivity imaging along three profiles (red lines) interpreted by the crushed/weathered rock (yellow color) and the integral/fresh rock (red color) and the faults (dashed red lines) for: (a) inner view of 3D ERT, (b) outer view of 3D ERT, (c) different depths including 3D ERT (inner view), (d) the outer view of 3D ERT with different depths.
