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.
Less than an hour after the earthquake, the first of many tsunami waves hit Japan's coastline. The tsunami waves reached run-up heights (how far the wave surges inland above sea level) of up to 128 feet (39 meters) at Miyako city and traveled inland as far as 6 miles (10 km) in Sendai.
