Just saw this brilliant cartoon on the topic. This boffin /geek sitting among all this technologia saying " Our new tsunami-warning will be 10000 messages in bottles dropped into the sea. If you find one floating thru your house there is a 99.9% probability this is not a false alarm" LOL
Bit of a cock-up , what?. But better that than what happened in Thailand with all the Northern Hemisphere geophysicists watching their screens for hours and nobody finding the International Dialling code for Thailand
