One year on, perhaps the most surprising thing about the Fukushima crisis is that nothing is really that surprising. Almost every problem encountered was at some point foreseen, almost everything that went wrong was previously discussed, and almost every system that failed was predicted to fail, sometimes decades earlier. Not all by one person, obviously, not all at one time or in one place, but if there is anything to be gleaned from sorting through the multiple reports now being released to commemorate the first anniversary of the Tohoku earthquake and tsunami–and the start of the crisis at Fukushima Daiichi–it is that, while there is much still to be learned, we already know what is to be done. . . because we knew it all before the disaster began.
