Size of wave[edit]

Let me get over the concept that 75 years later they built nuclear power plants right where this wave hit. Okay. I have my doubts on the size of the wave. I think the figure of 34 meters is elevation of land not height of wave.  Randall Bart   Talk  00:54, 19 March 2011 (UTC)

The url for source that I originally used does not seem to be working, however see the run-up heights for the tsunami as given by the NGDC/NOAA [1]. The maximum wave height given is 38.2 m. This is likely to be caused by the local shape of the seafloor, which can strongly amplify the wave - see also for example Iruma which was hit by a ~16 m wave in the 1854 Ansei-Tōkai earthquake although the general run-up values were about 6 m for that tsunami [2].
