BTW, I heard something on the news the other day, but I don't know if it's true or not. It has been reported that appearantly the people working on the Californian early warning system for earthquakes noticed that something was about to happen, but that the Californian coast wouldn't be affected, so they didn't give out a warning to their people. But they did not inform the now affected countries in South Asia either.
Thats' interesting. should you see a link would you post it?

The local Siesmologists, Kate Hutton and Lucy Jones (we know them because they are the faces we see soon ofter our shakers!!) didn't mention anything about it....

There are two different 'waves' that travel thru the earth's layers....

There are such things as 'precursor' quakes, the Hollywood hills were hit by some small quakes before the 94 Northridge earthquake, but how can anyone tell if they are 'pre' earthquakes as opposed to small 'alone' earthquakes???
