You would need approximately 5 TsarBomba's to produce the energy in this quake.

We do not live on a still planet.  Whats shocking is that we seem to only remember that long after we've forgotten it, and been so suddenly reminded, now and then.

Actually I think the models are suprisingly accurate these days .. a lot of computing power goes into Pacific swells prediction after these events.  I know that there is big, big iron modelling - and using input from real events - these wave motions.  


Impressive that they were able to give up to a minute alert by SMS to everyone, also, of the quake event!
