Now you know why geologists love row planting: The right-lateral nature of the fault slip (whichever side you are on, the other slides to the right) could not be clearer. The fault rupture extends for about 30 km (20 mi) along the previously-identified Futagawa fault and northern Hinagu fault. Fault maps may not depict all active faults, but they tend to capture the ones on which M≥7 shocks can strike. The shaking is strongest along the fault, and any structure straddling the fault will be destroyed. Japan, the U.S, New Zealand, Turkey, Italy, and Greece have among the best fault maps in the world. The enormous effort this mapping takes clearly pays off.
