Tsunamis are dificult to predict and it is even more dificult to predict their magnitude. Here is an interesting link on Tsunamis related to todays quake: Tsunami, Unpredictable Threat

How does a quake of 8.3 cause a smaller tsunami than a smaller quake of 7.8? I beieve the tsunami that killed 230,000 people was caused by a quake smaller than this one. How does that work? Is it because the quake is closer or further from the surface?

I guess I was writing my post when you posted Terapin.That's a good link, it just answered most of my questions.

WOW! Look what it did to seismographs around the world! VERY interesting stuff...

It is not the size of the earthquake, but the type of earthquake that creates a Tsunami. Some earthquakes in the water involve the ground moving in a way where the ground under the ocean is pushed up. This creates a Tsunami. Many earthquakes involve the ground moving side to side, which does not create a Tsunami. A huge earthquake in which the earth moves side to side will create a small Tsunami or no Tsunami at all, while a modest size earthquake in which the earth is pushed up can create a large Tsunami.
