Estimation of the nucleation level. a Average slip velocity plotted against the time remaining before the mainshock for parameter sets A–C. Black curves represent events indicated by blue arrows in Figs 2 and 3. Grey curves represent other mainshocks shown in Fig. 2. Red lines are fitted power law functions. Red text gives the estimated values of the nucleation level. b Results of parameter studies. The colors indicate the nucleation level D. Parameter sets A–C shown in a are denoted by squares
