Tsunami effects of a nuclear explosion

Sea surface nuclear explosion arouses a tidal wave of water.

How does this kind of wave compare to naturally occurring tsunamis? E.g. what would be the potential of a 100KT bomb 100km away the from shore to flood that shore?

• If you are interested in comparing the power of natural events (as well as this tsunami problem), you should compare the energy of atomic bombs to, say that of hurricanes like Katerina in New Orleans.....you may be surprised at what you discover: look at: en.wikipedia.org/wiki/Orders_of_magnitude_%28energy%29 – user74893 Mar 22 '15 at 15:48

• You could also point out that the seismic moment of the 2011 Japan quake was estimated at $3.9 \times 10^{22} \ J$ or ~9,321,223,709,369 tons of TNT = nearly 10 trillion tons of TNT (nearly 200,000 times the Tsar Bomb)... – honeste_vivere Feb 3 '16 at 13:57
