Fig. 2

Snapshot of the quasi-static evolution of fault slip for a single patch of \(R = 20\;{\text{km}}\), \(w_{c} = 0.4\,{\text{m}}\), \(w_{0} = 0\,{\text{m}}\), and \(\gamma = 2\), in terms of a slip deficit and b shear stress. At approximately time step 70, the peak in slip deficit is observed. c Time step necessary to reach the peak in slip deficit, with variable R and \(\gamma\) (Table 2). All the cases (γ = 1, 1.1, 1.5, and 2) are superposed, represented by solid large symbols (crosses: γ = 2; triangles: γ = 1, 1.1, and 1.5) and lines. The pale gray small circles and lines represent the cases where \(w_{c}\) is not scaled with patch size R (\(w_{c}\) = 0.4 m fixed). The small pale gray circles and lines represent the cases where \(w_{c}\) is not scaled with patch size R (\(w_{c} = 0.4\,{\text{m}}\) fixed). d Peak slip deficit at the center of the patch for each case. Markers are the same as in the previous panel
