Well clearly, it was necessary and I don't understand why it isn't
viable. Some experts have thought it necessary, too - there was a
recent conference on this very subject and the participants must be
kicking themselves that it didn't take place a few years ago with,
possibly, a warning system up and running by now. The Pacific Tsunami
warning system is an established model to base it on.

AFAICT, there were 12 destructive Tsunami's in the pacific basin in the
past 10 years.

Are deadly Indian Ocean tsunamis really 1 in 700 year events?

IANE, and I am relying mostly on sound-bites, one of which is that this
is Sri Lanka's first recorded (destructive?) Tsunami.

I
wouldn't have thought the conference would even have been suggested if
that were so. Or are we talking about 9.0 earthquakes in the Indian
Ocean? Which is not the same thing at all, is it?

I understood it to be that there was a major slipping of the Indian
plate and the Eurasian plate every 700 years. ICBW, and there are, of
course, other sources for geological activity.
