Tonga Boom! Undersea volcano erupts off Tonga
Imagine being on a fishing boat making a holiday video and then the whole ocean explodes around you. Well that’s not exactly what happened, but it would be a good story…
According to the Global Volcanism Program, this volcano started to erupt on the 16th or 17th March and has been going since. This video shows a team of scientists who took their boat out to the site to capture footage and record local and wide-spread changes. Apparently, no-one has been hurt by the volcano.
To see some aerial photos of the volcano, with coordinates, visit the ASTER volcano archive.

As you can see, the plume of ash and steam is huge. A line from the AP states “the eruption does not pose any danger to islanders at this stage, and there have been no reports of fish or other animals being affected” – other than by the great big explosion, then.
