Thank you for finding this article. We all know that in the end, Chernobyl had to be encased. Google "Chernobly Disaster" and pick the wikipedia article. It has a really good picture of the reactor after it blew.
At midnight on March 11th, the cusp of the 7th house in Fukushima was 5:08 Gemini - exactly conjunct the asteroid "Chernoby" in the February 11, 1889 National chart - 5:08:59, which is trine transiting "Chernoby" 5:16 Aquarius. That very day all hell broke loose in Fukushima.
Furthermore, their 2013 Solar Return has 22:30 Virgo as the 4th house cusp, (the end of the matter) which is the MC of the Midnight chart on March 11th (which had the Moon 22 Taurus). It also has Pluto 10 Capricorn, smack on the 7th house cusp.
Then you have Uranus 6 Aries, "Chernoby" 6 Taurus, Jupiter 6 Gemini. With natal "Chernoby at 5:16 Gemini in the national chart, Jupiter is sitting right on it!
Bury these monsters now before it's too late.
