From: Focal mechanisms and stress field in the Nobi fault area, central Japan
Inverted maximum principal stress σ 1 in the Nobi fault area. An additional data file shows the results in more detail (see Additional file 2). One red and two black lines at each grid point indicate the azimuth of σ 1 and the range of estimation error, respectively. Bold black lines show the seismic fault ruptured by the 1891 Nobi earthquake. The 35.5° N and 35.7° N lines of latitude are drawn. The stress tensor inversion was conducted in the four layers with depths of a 2–7 km, b 5–10 km, c 8–13 km, and d 11–16 km
