  • McKenzie1 proposed that the direction of subduction beneath an island arc will reverse following arc–continent collision. Dewey and Bird2 suggested that such an arc polarity reversal occurred in northern New Guinea; Johnson and Molnar3, however, proposed two alternative models of plate convergence that could explain the observed seismicity. We present here a spatial seismicity study of the Solomon Islands region which has revealed the existence of two juxtaposed Wadati–Benioff (W–B) zones of… CONTINUE READING
