Figure 10. Distribution of the average seismic moment rate since 1857
(r1) and 1871 (r2) as well as the slip
(r3) and time-predictable (r4) bounds of
the seismic-moment rates determined from 50,000 Monte Carlo simulations. The
distribution designated as r5, not shown on
Figure 9, is derived from a
least-squares fit to the cumulative moments, with each year contributing one
data point. The bin width is 0.1 x 1025 dyne cm/yr.
