The earthquake today is among other things a governance test. It's a bit too early to say, but it looks as if there's been a huge improvement in preparation throughout the Indian Ocean since 2004.
From what I can tell so far, sirens went off as they were supposed to. Warnings were issued promptly throughout the region. Evacuation took place promptly. People did exactly what they're supposed to do--they rushed away from the coastal areas as fast as possible. It looks as if Thailand, in particular, has vastly improved its preparation.
I don't want to be optimistic too soon, but I hope this means the world is getting better at preparing for these things.
Wouldn't that be good news?
Update: This video--not sure of its provenance--shows many people running parallel to the coast rather than away from it, which suggests there's still quite a bit of work to do.
