Underwater Explosion

[Saitek]

Tusamis get formed because of movement on the sea-bed. This isn't a missile, or a bomb or even a mile of TNT, this is huge plates holding up the whole sea moving or pulling apart. The power is absolutely massive and the plates may only need to move a few centimeters for a catastrophic sucession of waves that can wipe out whole islands.

I didn't watch the video, and haven't been following the thread. However, I thought I would let you all know that every time I see this topic I think that the name of it is "Underwear Explosion"

The Earthquake that caused the Tsunami in 2004
had a magnitude equivalent to 0.8 Gigatons !!!! of TNT.. that

Interesting but 11 feet is nothing to be quite frank and there would be plenty of those size waves around the world all the time. That isn't even 4 meters and even around the calmer waters of Britain we could get that in bad weather.

That is true, but a wave has limited power to travel when it is only powered by nature. If it has an earth quake of even an atomic explosion behind it the power is far greater. Just look at some of the Tsunami videos, the wave was only a meter or so high, but the mass of water and the power behind it was the main factor.

The Tsunami wasn't a wave tens of meters high. It was a couple of meters at most. It was just unfortunate that it hit low lying islands around the indian ocean.
