Examples of the temporal evolution of \(\Delta {\text{CFS}}\) on an inland fault. The apparent coefficient (\(\mu^{\prime}\)) and the intrinsic loading rate (\(\Delta \tau_{s}^{\text{intrinsic}}\)/year) in the inland fault are 0.1 and 0.5 kPa/year, respectively. a Case of negative coseismic \(\Delta {\text{CFS}}\) for dextral faults. The solid and dotted blue lines indicate \(\Delta {\text{CFS}}\) for faults located 150 km and 300 km from the upper-edge of the megathrust fault, respectively. The dark and light blue-shaded areas represent the active periods of these faults, respectively, and b case of positive coseismic \(\Delta {\text{CFS}}\) for the sinistral faults. The solid and dotted red lines indicate \(\Delta {\text{CFS}}\) for faults located 150 km and 300 km from the upper-edge of the megathrust fault, respectively. The dark and light red-shaded areas represent the active periods of these faults, respectively. However, the dark red-shaded areas show only during megathrust earthquakes
