Figure 6From: Stress state in the upper crust around the source region of the 1891 Nobi earthquake through shear wave polarization anisotropyAverage splitting parameters at each station. The orientation and the length of each bar indicate the average ϕ and the average δt n at each station using the results of this study and Hiramatsu et al. (2010). Red bars indicate that the angular difference between the average ϕ and the orientation of the principal compressional axis of the strain rate is within 30° and that the data number is greater than, or equal to, 3. Purple bars indicate that the angular difference is within 30° and the data number is smaller than, or equal to 2, and light blue bars indicate that the angular difference is greater than 30°. Gray lines are Quaternary active faults. Black lines show the source fault of the 1891 Nobi earthquake.Back to article page
