Figure 16

Schematic model of the evolution of deformation and physical property transitions in the Nobeoka Thrust. The vertical axes are porosity, resistivity, P-wave velocity, and shear stress of the rocks as labeled for each curve. Deformation in the intact zone is more intense near the main fault core, whereas deformation in the surrounding damage zone increases with distance from the fault core. The extent of physical property transitions that indicate strain-hardening and strain-weakening processes are likely to be proportional to the magnitude of deformation.
