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?

  • $\begingroup$ 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 $\endgroup$ – user74893 Mar 22 '15 at 15:48

You asked a similar question on worldbuilding for a story.

Hit youtube for Operation Crossroads, Baker test. The US Navy detonated a 21kt device 90 feet underwater. Produced a nice fountain but no overly-destructive wave action after a few kilometers.

A few years later, Castle Bravo (15Mt) also failed to produce any significant damage* outside the immediate vicinity.

Natural tsunamis, like the one that damaged Japan a few years ago, release far, far more energy than man has learned to control.

  • Yes, I'm deliberately ignoring radiological damage. Go find his question on worldbuilding.
  • $\begingroup$ 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)... $\endgroup$ – honeste_vivere Feb 3 '16 at 13:57
