(Left) Principal stress and pore fluid pressure estimated by Kitajima et al. (2017). (Right) Estimated pore pressure ratio, normalized pore pressure ratio, and stress ratio. SH: maximum (compressional) horizontal stress, Sh: minimum horizontal stress, Sv: vertical stress, Pp: pore fluid pressure, and Phyd: hydrostatic pore pressure. λ = Pp/Sv, λ* = (Pp-Phyd)/(Sv-Phyd). The dotted curves are the stress and pore fluid pressure models used to calculate the slip tendency, Ts
