It looks as though a nuclear meltdown is taking place in Japan after the 1-2 destruction of the 8.9 earth quake followed by the tsunami. Videos are appearing of some of the nuclear facilities seeing smoke after explosions. You make the decision as to what is really going to happen after seeing this video:
Now at the moment the news is focusing mainly on multiple reactors in jeopardy of a meltdown. This would be a major worldwide disaster and follows 2 previous nuclear disasters in USA and in former Russia now Ukraine in Chernobyl.
It is unknown how many nuclear power plants are in jeopardy of melting but clearly this region in Japan just north of Tokyo is very unstable. The area has been hit by a massive 8.9 earthquake and nobody knows if there are more earthquakes on the horizon.
