Subduction zone initiation types

Illustration of the three types of subduction zone initiation (SZI) events. As outlined in Crameri et al. (2020), the SZI type is either Newly destructive (a subduction fault establishing from an intact-plate portion or some sort of non-subduction-related plate weakness), Episodic subduction (a subduction fault establishing at the same location following a previous, yet terminated subduction zone with the same polarity), or Polarity reversal (formation of a new subduction fault with opposite polarity to the fault of the pre-existing, terminating subduction zone).
