Fig. 4From: Geometrical dependence on the stress and slip tendency acting on the subduction megathrust of the Nankai seismogenic zone off Kumano(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, TsBack to article page
