That tsunami didn't travel far inshore, but others did. Ted argues that a tsunami that hit the Shoalhaven delta near Nowra, between 5000 and 4000 years ago, ran 10 km inland, while deposits near the Blue Mountains hint that another tsunami ran over cliffs more than 60 m high, and then rushed inland. A similar event today would have the potential for widespread destruction.
Tsunami Evacuation Zones Important Map Notes Remain at least 100 feet away from inland waterways and marinas connected to the ocean due to wave surges and possible flooding. If possible, remove or deploy vessels to deep water (at least 100 fathoms). Structural steel or reinforced concrete buildings of 10 or more stories provide increased protection on or above the fourth floor. The evacuation zone is a guideline and should be considered the minimum safe evacuation distance. These maps do not consider the destructive effects of a locally generated tsunami. If you feel shaking, move inland immediately, well away from the evacuation zone. By County
