| Abstract: | A chaotic fault interaction model previously developed for the San Andreas Fault System and the Nankai Trough (examples of transform fault and subduction dominated tectonic regimes, respectively) is here applied to the large-event seismicity in the New Zealand region, where the interacting blocks of the model are taken to be those parts of the Indo-Australian plate boundary that are, from north-east to southwest, subduction dominated, ‘transpressional’, and transform-fault dominated. The model suggests a shorter term recurrence of large events than do simple seismic cycle approaches. |
