What's envisioned for the Indian Ocean is a new tsunami warning system,
We're developing a prototype system that will interface tsunami computer simulations with buoy observations and earthquake information to make a forecast at the beach. That will be a step forward.
They need warning centers, computer modeling, people educated in evaluating information and infrastructure to allow the information to get to people on the beach.
The basic criteria is to get a warning out ... within 10 and 20 minutes.
