Jesus Christ! An 8.9 Earthquake struck near Japan, 10m Tsunami followed

[Sapphire]

From what I undestand from SC:

No, there is no meltdown. The release of irradiated material was due to pressure-relief efforts (releasing some of the steam from the pressure vessel), and it was this released steam that caused the subsequent explosion above the rector. Water cracked into hydrogen and oxygen by the heat, which was mixed with water vapour and a tiny quantity of radioisotopes in the steam, recombined explosively.

And that makes the most sense to me. I think they are still trying to figure out how to cool the reactor cores. A lot sounds like media-terror hype. The possibility that is completely self-destructs is minimal, according to them.
