Undersea volcano erupts off Tonga coast

An undersea volcano has been erupting for days near Tonga. The steam and ash column first appeared on Monday morning, after a series of sharp earthquakes.

Scientists sailed to inspect the scene of shooting smoke, steam and ash thousands of meters into the sky above the South Pacific ocean.

Geologists say that spectacular columns are spewing out of the sea near the southwest coast off the main island of Tongatapu, an area where up to 36 undersea volcanoes are clustered.

Authorities say the eruption does not pose any danger to islanders at this stage.
