            where λ is the pore-fluid flow focusing factor of the rectangular fault of a large
            aspect ratio; β is the aspect ratio of the rectangular fault; α is the permeability ratio
            of the fault to its surrounding rock.
              Since the vertical velocity of the injected fluids due to the lithostatic pore-fluid
            pressure is equal to 1.6 × 10 –9  m/s and the numerical solution for the maximum
