Japanese officials announced on Tuesday morning that they raised the event level at Fukushima Daiichi nuclear power plant from 5 to the maximum level of 7, the highest on the international scale for nuclear incidents and the same level assigned to the 1986 disaster at Chernobyl.
The decision to raise the threat leve was made after radiation of a total up to 630,000 terabequerels had been estimated at the stricken plant.
The level 7 signifies a "major accident" with widespread health and environment effects.
But it's considerably different from Chernobyl.
Fukushima has released only about 10% of the total radiation released 25 years ago at Chernobyl.
What we fear the most is not only the nuclear crisis but also the economical collapse after the announcement of highest nuclear alert, I think.
