Hi Fred,
I've previously worked with the Bureau of Meteorology (BoM) here in Australia, and they propagate several of these type of warnings between meteorological, seismic and aviation agencies here and around the world using message switching systems.
The Internet is used for dissemination in a number of ways. In the late 90's tcp/telenet sessions were in use on extranet/leased line links, and pager, fax and other direct to the public warning dissemination systems were in use.
It's probably worth trying to get input from existing agencies tasked
with this role in various countries, and some organizations (such
as the World Meteorological Organization) may be interested in contributing time and effort in this direction, but I don't know.
Perhaps there are also existing systems which may be used as a model.
Unfortunately, I don't believe that there is an actively monitored tsunami service in the Indian ocean, which may have been able to transfer such warnings. The role of a generic, authenticated, internet-based warning system may be useful in furture though.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Structure of an International Emergency Alert System
Author(s) : F. Baker, B. Carpenter
Filename : draft-baker-alert-system-00.txt
Pages : 19
Date : 2005-1-11
The authors propose a way in which people could be warned of an impending event in a geographic region. This is similar to and may use services such as the US Emergency Alert System, but differs in that message distribution is targeted only to the affected locality.
A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-baker-alert-system-00.txt

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
