Active Volcanoes Endanger Japan’s Operating Nuclear Power Stations: Mount Aso Awakened Explosively; Sakurajima Already Awake

Japan’s Mount Aso volcano erupted explosively on Saturday, 8 Oct., 2016, and volcanic “ash was falling as far as 320 km (200 miles) away, … Kyushu Electric Power Co said the eruption had no impact on its Sendai nuclear plant, which is about 160 km (100 miles) south of Mount Aso“(Reuters, 8 Oct. 2016). Sendai nuclear power station has two reactors online. The other nuclear power station online is Ikata, with one reactor operating.

With a change in wind direction ashfall from Mount Aso and/or Sakurajima could endanger Japan’s operating reactors. As can be seen on the map, Ikata Nuclear Power Station is closer to Mount Aso, and Sakurajima to Sendai Nuclear Power Station. Ash plume forecasts for both appear at the bottom of this post.

Disruptions due to a major volcanic eruption, as well as ashfall could lead to nuclear meltdown:

Japan’s Mount Aso volcano erupts, no injuries reported

TOKYO (Reuters) – Mount Aso, a volcano on Japan’s main southern island of Kyushu, erupted early on Saturday, Japan’s Meteorological Agency said, spewing volcanic ash 11,000 meters (7 miles) into the sky.

“Mount Aso, a volcano on Japan’s Kyushu island, has been erupting sporadically for decades. Smithsonian’s Global Volcanism Program lists 38 separate eruptions since 1950, with the most recent beginning on December 8, 2014. All of these eruptions have occurred at Naka-dake, a cinder cone located within Aso’s massive caldera.”
