Recent research has revealed much geomorphological evidence for major tsunamis on the southeastern coast of Australia prior to British settlement in 1788. This discovery is important because this tectonically very stable coast was believed to be safe from the hazard of tsunamis because no major tsunami has occurred here in the last 200 years. But high level marine deposits of Holocene age along the coast south of Sydney show that tsunamis ran up to heights of >30 m, and at one site to heights probably >100 m. Developing a chronology for these catastrophic events is of great importance to the …

The Jervis Bay area offers а diversity of landforms that do not fit within con¬temporary views of coastal evolution. Field evidence indicates that catastrophic tsunami have had а significant impact on the coast and its hinterland both within and outside the embayment. Runup has overtopped cliffs 80 m above sea level and deposited chevron-shaped ridges to elevations of 130 m on the southern headland. Boulders, up to 6 m in diameter, have been deposited in an imbricated fashion against cliffs, on clifftops, and along shoreline ramps. Bedform features and the size of transported material indicate flow depths up tо 10 …
