Figure 4From: Multiple damage zone structure of an exhumed seismogenic megasplay fault in a subduction zone - a study from the Nobeoka Thrust Drilling Project Fracture density in the hanging wall. Fracture density (number of fractures per 1Â m) in the shale-rich intervals, sandstone-rich intervals, and the damage zone in the hanging wall. Note that fracture density is largest in the sandstone-rich intervals. Red line marks the location of the main fault core between the hanging wall and footwall.Back to article page
