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.
For instance, the earthquake off the shore of Japan in 2011 created tsunamis reaching the United State's pacific coast line. The 2011 Tsunami in Japan Most scientists reported that the 33-foot tsunami wave made it 6 miles inland, with washed up shrapnel and water reaching 10 miles or more inland. There are various factors that determine how far inland a tsunami can go. Here is a list of factors involved: The terrain of the land and the height of the tsunami wave. If the land is mountainous the tsunami would probably not go very far; however, if it is lowland, it may wash inland for several kilometers.
