Besides 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.
