Fremrinámar, NNE of Askja and SE of Mývatn lake, is a volcanic system that is constructed over the Ketildyngja shield volcano (center). Associated fissure systems, including the Sveinar fissure, extend 130 km to the N coast of Iceland. Mývatn lake formed as a result of the eruption of the 70-km-long older Laxarhraun lava flow from Ketildyngja shield volcano about 3,800 years ago. The latest eruption from Fremrinámar produced the Búrfellshraun lava flow about 2,500-3,000 years ago.
