Figure 9: Comparison of recurrence
rate estimates based on m = 6, 7, 8, and10 near-neighbor model (labeled
lines) calculated using equations 3 and 4 and the observed mean estimate
of recurrence rate (heavy line with solid squares). The m = 7 and
8 near-neighbor models best reflect recurrence rate before 1.0 Ma, given
the uncertainty in the vent ages. The rate of decrease in recurrence rate
after 0.75 Ma is not well-captured by these models.
