SHmax orientation from the numerical boreholes and thrust activity. The SHmax orientation is given by the averaged principal stress vectors in the cylinder centered at Hole-A (black) and Hole-B (red) with a radius of 5 mm. The positions of Hole-A and Hole-B are illustrated by the circles in Fig. 6. The line and cross show the angles of SHmax from the x-axis at the shallow part (0.01 < y < 0.015) and deep part (0.005 < y < 0.01). The thrust activity is defined by the average velocity at 0.64 < x < 0.69 and 0.4 < z < 0.6 shown in Fig. 6.
