This research examines tsunami deposits in the geological record at Purau, Port Levy and Pigeon Bay. Three paleotsunamis that inundated the area were identified, dating from 660-775AD, 1300-1400AD and 1604AD (this last event has been identified and documented elsewhere, hence its precise date). It also found evidence of up to four historic tsunamis - the 1868 Peru, 1960 Chile, 2010 Chile and 2011 Japan tsunamis.
This research contributes to our understanding of how tsunamis behave around Banks Peninsula, and their impacts.
