Figure 13: The relative success of
the spatio-temporal model can be evaluated by comparing the recurrence
rates estimated by the model at the locations of subsequent volcanic events
(open circles) with the average recurrence rates of volcanism, (dashed
line) and (solid line). The distribution of model recurrence rates,ln(p),
in
the entire SVF are also shown (heavy solid line) for comparison at (a)
1.75 Ma, (b) 1.5 Ma, (c) 1.0 Ma, and (d) 0.75 Ma. Recurrence rates in the
areas of subsequent volcanic events, estimated using the spatio-temporal
model, are significantly greater than average values at 1.75, 1.0, and
0.75 Ma, and not significantly different at 1.5 Ma. Subsequent volcanic
events for each interval are mapped in Figures 12a - 12d. Standard deviations
on lt(p)
and l(p) estimated
as SQRT(n) / At.
