Schematic illustrations to estimate pore fluid pressure ratio by using the Mohr circles. a Equal-area projection showing stress axes and fault plane with the slip direction. The stress is the reverse faulting type of stress regime. b Normal stress magnitudes on the fault planes calculated according to the optimal stresses. σ1, σ2, and σ3 are the maximum, intermediate, and minimum compressive principal stresses, respectively. The stress ratio is 0.6. This figure shows the Mohr’s diagrams that depicts the fault data. Horizontal and vertical axes show the normal and shear stresses acting on fault planes. Gray lines show the fault strength when λ = 0.00, 0.25, 0.50, 0.75, and 1.00. When we used a value of 0.6 for the friction coefficient μ, the values of λ for the fault planes A and B are 0.00 and 0.42, respectively
