Spatial distribution of A − B (a) and L (b) on the model fault assumed in the simulation for the Nagata law. Conditionally stable circular patch and small unstable circular patch are denoted by red and green circles in (a). A and c are assumed to be uniform over the model fault. Here, A = 3.3 MPa and c = 2. Additionally, (A − B)1 = −0.222 MPa and (A − B)2 = 0.222 MPa. For group 1, L 1 = L 2 = 0.0046 m, L 3 = 0.0021 m. For group 2, L 1 = L 2 = 0.0049 m, L 3 = 0.0024 m. (A − B)3 is variable
