Relationship between fracture density and physical properties in the hanging wall and footwall. Relationship between fracture density (number of fractures per 1 m) and resistivity, P-wave velocity, S-wave velocity, porosity, and density for the surrounding damage zones (sdz) in the hanging wall and footwall. Note that below a fracture density of 20 (per 1 m), the resistivity, P-wave velocity, density, and S-wave velocity decrease with an increase in structures, implying strain-weakening. However, above a fracture density of 20 (per 1 m) (colored red), these properties increase with an increase in structures, indicating strain-hardening.
