The case of the magical Tsunami Early Warning System!
Early warning networks are of no use if the relief and emergency aid agencies aren't able to communicate. Putting in the sensors is the easy part, the difficult part would be setting up a comprehensive disaster management system.
I'm putting together news stories and opinions on this particular idea here - http://tsunamiwarning.blogspot.com/
At the moment I'm merely collecting news stories, but I'd also like to produce a position paper out of all of this input. The Wiki page for the position paper is here. Primary remedies that the government can provide are (1) regulatory loosening of the noose that's choking community radio in India; (2) creating a tiered support system for emergencies that actually works; (3) Getting out of the way when an aid agency actually wants to help.
If any of you would like to contribute actively to the blog, I'll be happy to provide write privileges to the blog. I also welcome ideas on where to head with this effort. I'm convinced the guvmint will install an expensive piece of hardware in the ocean bed and forget the real reason this disaster happened. In a few years I'm sure we'll come to know that the initial budget for the warning systems didn't really plan on replacing the hardware or training the staff adequately. It'll become yet another piece of junk on the ocean floor.
If some of my gentle readers could point to the blog on their LJs, I'm sure the resulting attention will be more than welcome.
