Surtsey ("Surtr's island" in Icelandic, Icelandic pronunciation: [ˈsʏr̥(t)sˌeiː] ⓘ) is an uninhabited volcanic island located in the Vestmannaeyjar archipelago off the southern coast of Iceland. At Surtsey is the southernmost point of Iceland. [1]
The eruption style is named after an eruption off the southern coast of Iceland in 1963 that caused the emergence of a new volcanic island, Surtsey. [1] Surtseyan eruptions are phreatomagmatic (also known as hydromagmatic) eruptions, in that they are violently explosive as a result of vigorous interaction between rising magma and lake or sea water.
The Grímsvötn volcano in Iceland is a sub-glacial volcano, located beneath the Vatnajökull ice cap. For a typical sub-glacial eruption, overlying glacial ice is melted by the heat of the volcano below, and the subsequent introduction of meltwater to the volcanic system results in a phreatomagmatic explosion.

Kilauea – Hawaii, United States – the volcano has a long record of phreatic explosions; a 1924 phreatic eruption hurled rocks estimated at eight tons up to a distance of one kilometer. [7] Surtsey – Iceland, 1963–65; Taal Volcano – Philippines, 1965, 1977, 2020; Mount Ontake – Japan, 2014 (see 2014 Mount Ontake eruption)
The island of Surtsey in the Atlantic Ocean is a basalt volcano which breached the ocean surface in 1963. The initial phase of Surtsey's eruption was highly explosive, as the magma was quite fluid, causing the rock to be blown apart by the boiling steam to form a tuff and cinder cone. This has subsequently moved to a typical pāhoehoe-type ...
Iceland is one of the most active volcanic regions in the world, with eruptions occurring on average roughly every three years (in the 20th and 21st century until 2010 there were 45 volcanic eruptions on and around Iceland). [1] About a third of the basaltic lavas erupted in recorded history have been produced by Icelandic eruptions.
