a Plots of the normalized shear and normal stresses on faults on a three-dimensional Mohr diagram for a grid point (x = 10, y = 9, z = − 2). Pore pressure indicators P_p are calculated as P_p = σ_n − τ/μ, where μ is assumed as 0.6. Sizes of circles represent the difference of misfits between the fault plane and auxiliary plane (misfitdiff); coloring indicates only data with misfits on the fault plane greater than the error of focal mechanisms, 10°. b Histogram of misfits. c Relationship between azimuths and dip angles of the fault planes. Misfits are also indicated by the sizes and colors of circles. d Relationship between magnitude and misfit. e Histogram of the pore pressure indicator, Pp
