BLUE: Weighted mean (thick line) and min/max (thin lines) on-fault supra-seismogenic nucleation rate.
LIGHT BLUE: Weighted mean (thick line) and min/max (thin lines) on-fault sub-seismogenic nucleation rate.
BLACK: Weighted mean (thick line) and min/max (thin lines) on-fault sub- + supra-seismogenic nucleation rate (sum of dark and light blue curves).
RED: Weighted mean (thick line) and min/max (thin lines) UCERF2 on-fault supra-seismogenic nucleation rate (only for UCERF2 faults).
