Frequency of the normalized slip tendency computed from the 95% confidence region of the stress tensor in Fig. 2b. The inverted triangles show the normalized slip tendency of the best stress tensor. The gray dotted line indicates the boundary as to whether or not the fault is easy to move under the assumed stress tensor (Collettini and Trippetta 2007). For the case of a northern, b southern, and c SI faults
