List of volcanoes in Iceland

This list of volcanoes in Iceland includes 31 active and extinct volcanic mountains, of which 18 have erupted since human settlement of Iceland began circa 900 CE.
Volcanic zones and systems.
Iceland has four major volcanic zones surrounding an hypothetic hotspot: the Reykjanes zone (RVZ), subdivided in the Reykjanes Ridge (RR) (the Mid-Atlantic Ridge South of Iceland) and the Reykjanes Volcanic Belt (RVB) (on the main island); the West Volcanic Zone (WVZ); the East Volcanic Zone (EVZ) (extended to the Westman Islands, South of the main island); and the North Volcanic Zone (NVZ). The Mid-Iceland Belt (MIB) connects them across central Iceland.
In the Iceland's East Volcanic Zone (EVZ), the central volcanoes, Vonarskarð and Hágöngur belong to the same volcanic system; this also applies to Bárðarbunga and Hamarinn, and to Grímsvötn and Þórðarhyrna.
North of Iceland, the Mid-Atlantic Ridge is called Kolbeinsey Ridge (KR) and connected to the North Volcanic Zone via the Tjörnes Fracture Zone (TFZ). Also the South Iceland Seismic Zone (SISZ) is another fracture zone, that connects the East and West Volcanic Zones. Both fracture zones also include their own volcanic systems, smaller than those in the Mid-Iceland Belt.
Beside the hotspot area fragmenting the Mid-Atlantic Ridge, there are also two intraplate volcanic belts: Öræfajökull (ÖVB) on the Eurasian plate, and Snæfellsnes (SVB) on the North American plate. It is proposed that the east-west line going from the Grímsvötn volcano in the Mid-Iceland Belt (MIB) to the Snæfellsnes volcanic belt (SVB) shows the movement of the North American Plate over the Iceland hotspot.
