It's actually kind of interesting. After the disaster, the nuclear power plant near me moved it's backup generators literally on the top of a neighbouring hill -- it's about 100 meters above the entire complex. And they made another backup one on another hill. Once you know the problem, it's not hard to fix it. I admit to being a bit worried that now the generators are too far away from the power plant so that when an earthquake happens (we're 50 years overdue for a regular terrible earthquake) it will be disconnected. The irony will be lost if it happens, I'm sure...
That doesn't mean it's easy to realise the need to do that action, it means it's not a _complex_ action in itself.
