By the way, that '100 megaton' weapon? Actually more likely to be a 10 megaton device:

Still bad, but not 'likely to wipe out most of the eastern seaboard with one weapon' kind of bad.

Also, it's uncertain just how large a wave such a device could create, if the 10mt device detonated in the middle of San Francisco harbour, for example, it could probably send in a wave that was maybe ten meters high, which would wreck waterfront areas and that would be about it. If they detonated it off shore then most of the energy would slam straight into the continental shelf and a small wave might just destroy a kids sandcastle on the shore.

For the sort of city destroying device that is probably wanted you would need that 100mt to go off in the middle of the harbour and you'd probably need an entire submarine to put that bomb in, they barely managed to fit the Tsar Bomba into a Tu-95.
The Japanese tsunami reached 40 meters and the energy from the earthquake and tsunami was the equivalent of 9,320 gigatonnes or 800 million Hiroshima explosions.

In short, I don't think this is quite the devastating weapon that Russia thinks that it is, certainly compared to a conventional nuclear air or ground burst, and against inland cities it's completely useless.
