P- and T-axes adopted in the stress-tensor inversion. (Left) P-axis direction is indicated by the segments. Blue and green segments represent P-axes plunging ≤45° and >45° from the horizontal (e.g., strike-slip and normal-fault type), respectively. (Right) Distribution of the T-axes of the focal mechanisms is shown by the segments. Red segments represent reverse faulting events. Open circles denote the locations of the seismic stations. Other symbols are the same as in Fig. 1
