Toshitsugu Fujii, head of a government-commissioned panel on volcanic eruption prediction, said today a cauldron eruption at one of several volcanos surrounding the reactors at the Sendai plant in southern Japan not only could hit them but also cause a nationwide disaster.
Japanese regulators last month said the Sendai reactors fulfilled tougher safety requirements set after the 2011 Fukushima disaster. The authority ruled out a major eruption over the next 30 years until the reactors' retirement.
