The East Volcanic Zone is divided into 5 parts shown here:
Each of those polygons is somehow special, and No. 1 fits the area often pointed out as the hot spot of Iceland. It is being pulled to the east and south (as the blue lines show local downwelling) against the main drift direction towards NW. No. 2 and 3 belong to rift zone, but 4 and 5 are sometimes called South Volcanic Zone, because it all belongs to the Eurasian tectonic plate and is not being torn apart. No. 4 is the area of Eyjafjallajökull and Mýrdalsjökull, and No. 5 is the polygon of Vestmannaeyjar.
