Two submarine volcanoes in this area.

East Gemini

It is a submarine volcano at a depth of 80 m located about 100 km south of Aneityum Island, halfway between Tanna and Matthew Island.

The first observation of its eruptive activity was made by the New Zealand Navy on 18 February 1996.

It is one of the many submarine mountains along the southern submarine extension of the New Hebrides volcanic arc and consists of an elongated NNE-SSO chain of submarine volcanoes surrounded by cones satellites.


West Gemini

Located at a depth of 30 m under water, this volcano has a well-developed marine life and therefore an older activity.
