Fremrinamur central volcano, NNE of Askja and SE of Myvatn lake, is a volcanic system that is being constructed over the Ketildyngja shield volcano (center). Associated fissure systems, including the Sveinar fissure, extend 130 km to the northern coast of Iceland. Iceland's renowned Myvatn lake formed as a result of the eruption of the massive 70-km-long older Laxarhraun lava flow from Ketildyngja shield volcano about 3800 years ago. The latest eruption from Fremrinamur produced the Burfellshraun lava flow about 2500-3000 years ago.

Ketildyngja shield volcano, the most prominent feature of the Fremrinamur volcanic system, contains a steep-walled summit crater. Associated fissure systems, including the Sveinar fissure, extend 130 km to the northern coast of Iceland. Ketildyngja was the source of a massive 70-km-long lava flow about 3800 years ago that was responsible for the formation of Iceland's renowned Myvatn lake.

The eastern rim of the summit crater of Ketildyngja shield volcano overlooks flat-lying lavas of the Fremrinamur volcanic system on the right and steep-sloped Pleistocene subglacial lavas on the left. The Fremrinamur fissure system extends 130 km north of Ketildyngja to the northern coast of Iceland.
