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