surtseyan eruption

Hydrovolcanic eruptions dominated by jets of wet tephra (scoria and ash) that result in the formation of tuff cones. The term "surtseyan" is generally used for volcanoes erupting through seawater. Named after Surtsey, a volcano which emerged from the sea off the coast of Iceland in 1963 (Vespermann and Schminke, 2000, p. 683).
