TOKYO (Reuters) - Japan warned on Saturday that a volcano 50 km (31 miles) from a just-restarted nuclear reactor is showing signs of increased activity, and said nearby residents should prepare to evacuate.
Sakurajima, a mountain on the southern island of Kyushu, is one of Japan's most active volcanoes and erupts almost constantly. But a larger than usual eruption could be in the offing, an official at the Japan Meteorological Agency said.
"There is the danger that stones could rain down on areas near the mountain's base, so we are warning residents of those areas to be ready to evacuate if needed," the official added.
The agency also said it had raised the warning level on the peak, 990 km southwest of Tokyo, to an unprecedented 4, for prepare to evacuate, from 3. Roughly 100 people could be affected.
Japan on Tuesday restarted a reactor at the Sendai nuclear plant, some 50 km from Sakurajima. It is the first reactor to be restarted under new safety standards put in place after the 2011 Fukushima disaster.
Critics have long pointed out that the plant is also located near five giant calderas, crater-like depressions formed by past eruptions, with the closest one some 40 km away.
Still, the Nuclear Regulation Authority (NRA) has said the chance of major volcanic activity during the lifespan of the Sendai plant is negligible.
