Fukutoku-Okanoba undersea volcano erupting, February 2010 (stills from Japanese Coastguard video)

Fukutoku-Okanoba is a submarine volcano which is part of the Volcano Islands group, which is about 1000 km south of the main Japanese archipelago. Submarine, but only just, for its summit lies a mere 14 metres beneath the surface. This week it has been erupting, the first eruption (or, if you are British news channel ITN, ‘smoke explosion’) of Fukutoku-Okanoba since 2005, and the Japanese Coastguard caught the eruption on video. Four still images from the video can be seen above, showing steam billowing out and some dark-grey ash erupting from the ocean.
