Hindsight is 20/20. From what I've been reading, it sounds like the plant could have handled an earthquake OR a tsunami of this magnitude... It's the combination of the two, along with the age of the reactor (Newer ones are more resilient), that's screwing things up. I remember hearing somewhere that the Fukushimi reactors were due to be retired soon... They're obsolete. Basically, the worst earthquake and tsunami in Japan's history hit in the worst possible location. It's not an issue of poor planning or bad design... It's an issue of the engineers expecting a disaster no worse than X, building it to withstand X * 10, and eventually getting hit by X * 100. This is Murphy's Law at work. I think Blue Oyster Cult said it best... "History shows us again and again how nature points out the folly of man."
Proud to have finally moved to the A-Ark. Which one are you in?

Not the case Ian. There have been plenty bigger Tsunamis, and I believe one bigger quake. Its easilly googleable, take a look.

So you're going to ignore the main point and nitpick? Fine. It was the largest earthquake to hit Japan in recorded history, accompanied by a large tsunami. Happy now?

Author of the Guardians Saga (Sci-Fi/Fantasy novels)So your main point wasnt prefixed with 'Basically'? ;)

You're ignoring the discussion point, and nitpicking the verbiage. Obviously you have nothing pertinent to say, other than playing Captain Hindsight to the Japanese, so I guess we're done here.
