Fukushima Japan Reactor 1 in Meltdown

NHK and Zero Hedge are reporting that the Reactor #1 at the Fukushima Daiichi nuclear power plant in Japan is in  state of meltdown.


While the situation at the Fukushima nuclear plant has been dire since the massive 8.9 magnitude earthquake and resulting tsunami that hit Japan on March 11, 2011, that it has released a lot of radiation – it has never been a true meltdown until today.

What does meltdown mean in this situation?  Well it’s not good.  Basically the fuel rods are fully exposed, and have subsequently dropped to the bottom of the reactor.

When this happened exactly, is anyone’s guess – as the disclosures and credible information that have been coming from TEPCO and the Japanese goverment have been suspect at each step of the way – with regards to the timing and fullness of disclosure.

Japan Aftershock - Powerful 7.4 Magnitude Earthquake Hits April 7, 2011

A powerful 7.4 magnitude earthquake aftershock hits Japan on April 7, 2011.

While this is a significantly powerful earthquake in its own right, this is considered to be an aftershock of the powerful Japan earthquake that hit the previous month (See this post about the March 11 Earthquake in Japan).

Bloomberg is reporting that there have been no reports to Japanese nuclear plants, but that a tsunami warning has been issued for Japan.  The Pacific Tsunami Warning Center has issued a bulletin on the aftershock but advises that a tsunami is not expected to reach Hawaii.

The Japan Meteorological Agency issued the following info about the earthquake, measuring it at 7.4 magnitude:
