Impressive science is being produced as a result of the 2004 Indian Ocean tsunami. The focus now must be on creating systems within national governments that will allow the best use of science. Modeling data on projected tsunami arrival times (if any) were available to all on September 12, 2007. There is no evidence that the government’s hasty evacuation order took into account any of this information. A new mathematical formula that could be used to give advance warning of where a tsunami is likely to hit and how destructive it will be has been worked out by scientists at Newcastle University.
