Despite the power of a nuke, i still do not think a tsunami can be created by this force. Why? Because an earthquake , which i firmly believe, causes WAY more damage (and needs WAY more power). Also, a nuke has 80% of its forces away from the ground. Ie, it goes UP/ Sideways. Which will NOT do that much to water as when a sudden shift goes on the surface (earthshift/quake). So it causes tons of water to shift all of a sudden, to cause a wave like that.
I am not convinced
