Tsunami chronology supporting late holocene impacts

The Holocene Impact Working Group (HIWG) has identified the location of at least eight impacts into the world’s oceans in the Late Holocene. Each of these was capable of generating large tsunami that should have left a geological footprint on adjacent shorelines. We have identified from shoreline tsunami deposits five known impact events (Fig. 1), two of which are associated with impact craters identified by the HIWG. The other three are associated with legends and historical descriptions. This paper presents the chronology of tsunami events in New South Wales (NSW) and Western Australia (WA)–on opposite coasts of Australia, and in the UK that are linked to impact events.
