a Qualitative stress change (inverse of luminosity change) across the experimental fault surface with respect to a reference frame at t = 0, not shown. Same event as Fig. 6b. Each frame is separated by ∆t = 0.1 s (frame I is at t = 0.1), reported with Roman numerals (panel b). Dotted lines indicate the rupture front position in the previous time frame. b Friction curve showing the timing of each frame in (a). c Luminosity with rupture fronts of panel a, dotted in white and nucleation site circled in yellow. d Rupture progression (dark to light) with nucleation site in yellow.
