The earthquake was bad.
The tsunami was worse.
If this nuclear reactor melts down, this will be catastrophic...

Meltdown Caused Nuke Plant Explosion: Safety Body
I'm not sure if the situation has changed but earlier I read about some scale for radioactivity fallout for such events that ranged from 0-7.

Chernobyl was listed as 7.
Three Mile Island was listed as 5.
The situation in Japan was listed as 4.

Not sure if this is still true though.
STALKER: Shadow of Fukushima
Odd that a reactor is named, "Fukushima". Saying it out loud sounds like "Fuckyoshitup". Thats what it's about to do. =/
Explanation of threat from a Nuclear Reactor Operator.

tl;dr this won't be another Chernobyl, and a meltdown really isn't a concern at this point.

Reports indicate the explosion was due to hydrogen, not a meltdown. It could also have been made worse by the onsite diesel generators.

The scale Cyberhound references is the INES.
It wouldn't necessarily be 'catastrophic' but granted the outer shell of the reactor lets out anymore nuclear fallout than it could result in a Chernobyl-Esq event.

However I doubt it would be nearly as bad.
All I know is that Japan is getting some heavy shit.
The entire island was apparently shifted 8 feet closer to North America. That is a helluva lot when talking about land masses.
I was in Mt Fuji Japan Wtf happned and i cant reach my boyfriend he was in tokyo ):. For some reason i ave internet connection in my house o_o.
Cool story, bro.
Now accepting applications for brotherhood of steel. Inquire within.
Update: "This event is now closer to a level 6, and it may unfortunately reach a level 7."

As I understand it, fission has largely stopped at the site, so we're talking non-volatile emissions into the atmosphere (which are then carried) to create something that could be classified as a level 7, and even then does not compare to the actual harm to life that something like Chernobyl created.

As the second largest cause of lung cancer in the US is radon gas radiation, released from quarrying the very rocks your continental shelf is made up of, this wouldn't seem to be much of a pressing issue for Japan (or anyone else) even if it did hit a level 7. I suspect the very bedrock of Cornwall, UK (notorious for background radiation) would inflict more on-going harm than a level 7 at this site. From a nuclear power point of view, it's a huge set-back though, as any failure of this scale is a problem and a risk to health.

More importantly the ongoing problem of supplying and keeping all the flood victims warm in sub-zero temperatures will be killing more people and cause more health problems than the nuclear reactors themselves will.

While this whole nuclear thing is an issue, it would do us well to keep a little perspective here.
