Fig. 5

Coseismic Coulomb stress (ΔCFF(0)) due to the Iburi earthquake for a the northern, b southern, and c SI faults. For each fault, the top panel shows the ΔCFF(0) resolved onto the target fault. The bottom panel shows the ΔCFF(0) on the receiver faults, which are distributed on the X = 18 km plane (dotted line in the top panels), assumed to have identical source parameters as each target fault. The black, blue, and green rectangles indicate the geometry of the northern, southern, and SI faults, respectively. In each panel, the red rectangle and yellow star show the fault model and hypocenter of the Iburi earthquake, respectively. The black circle in the top panel of c indicates observation point I1
