(a) Trade-off curve of stress tensor inversion showing the model length and data variance for the full range of possible value of the damping parameter e. Numbers indicate values of e at points marked by dots. (b) Inverted maximum principal stress (σ1) in the Atotsugawa fault area. Arrows indicate the azimuth of σ1 at grid points centered at rectangles. Numbers within each rectangle indicate the coordinates of the grid point and the number of the focal mechanism solutions used for the stress tensor inversion. Bold and thin lines express the Atotsugawa fault and the other active faults, respectively.
