Iterative inversion of stress and fault orientations. The plot shows: a the distribution of focal mechanisms of the mainshock (red beach ball) and aftershocks (yellow beach ball) of the fault parameters listed in Table 1, b P-axes (red circles) and T-axes (blue plus signs) and the corresponding principal stress directions (σ1, σ2, and σ3), c confidence of principal stress axes retrieved from random perturbation of the focal mechanism dataset. d Mohr’s circle diagram with the positions of fault planes, and e the stress ratio histogram for the 2017 earthquake sequence
