GNS volcanologist Brad Scott warned that submarine eruptions can be a danger to shipping.

An underwater volcano situated near Tonga named "Submarine Volcano III" has been erupting for over a week, according to a GNS scientist and Nasa images.

On January 31, a plume was seen emanating from a "submarine volcano" by University of Auckland geographers.

It is situated about 46km northwest of Tonga's capital, Nuku'alofa.

Volcanologists based in Tonga suggest that steam plume visible above water may be present, but cannot be confirmed due to cloud in the area.

In his post, Scott cautioned that "submarine eruptions can be a hazard to shipping".

Previous undersea eruptions in the area have sent cloud and smoke up to 20km into the earth's atmosphere.

The phenomenon has been detected in the area frequently since 1911, with the particularly large eruptions creating short-lived islands.
