Fig. 8From: Focal mechanisms and stress field in the Nobi fault area, central JapanDistribution of the stress ratio in the four layers with depths of a 2–7 km, b 5–10 km, c 8–13 km, and d 11–16 km. Bold red lines are the surface trace of the seismic fault ruptured by the 1891 Nobi earthquake. Thin black lines are other active faultsBack to article page
