From: Focal mechanisms and stress field in the Nobi fault area, central Japan

Group	Depth	N of F.M.	N of nodes	σ ₁-axis	R
1st	2–7	147	25	N107°±5° E	0.7 ± 0.15
2nd	5–10	327	62	N100°±7° E	0.8 ± 0.12
3rd	8–13	317	58	N96°±9° E	0.9 ± 0.11
4th	11–16	142	33	N87°±8° E	0.8 ± 0.15

^aDepths are in km, N of F.M. is the number of focal mechanisms included in each group, and N of nodes is the number of nodes with more than 10 focal mechanisms
