Volcanic zones and systems
Volcanism in Iceland

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.[3]

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.[4][5] 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.[6]

gollark: It does have cool challenges, like efficiently routing channels around.
gollark: Wait, what's *that* showing?
gollark: Also also, do you have some sort of modular cable bus interface for all of them, or just crazy wireless?
gollark: Also, I have no idea what kind of nice-looking materials would work nicely.
gollark: Both, I guess.
