Submarine volcano

underwater vents or fissures in the Earth's surface from which magma can erupt

Submarine volcanoes are volcanoes which are under the surface of the world's oceans. These volcanoes occur in a range of forms. Many create cone-shaped seamounts or flat-topped guyots.[1]

Superheated lava was photographed by a remotely-operated underwater robot at a depth of 4,000+ feet

Volcanoes in the ocean develop from cracks or holes in the earth's undersea surface.[2] Changes in the ocean floor are caused when magma flows or erupts from a site which is under water.

The presence of water alters the characteristics of a volcanic eruption.
