Schematic model of physical properties and shear-stress transition during rock deformation (e.g., Paterson and Wong 2010 ; Scholz 2002 ). The vertical axes are porosity, resistivity, P-wave velocity, permeability, and shear stress of the rocks as labeled for each curve. The increases in resistivity, and P-wave velocity, and the decrease in porosity during strain hardening and strain localization may correspond to the surrounding damage zone in the present study (arrows in orange), whereas the point where resistivity and P-wave velocity begin to decrease and the porosity begins to increase during localization is shown by the green arrows. The state of strain weakening may correspond to the brecciated zones (red arrows).
