Fremrinamar

Estratovolcán · Iceland · 970 m

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.

Resumen geológico

The Fremrinámar volcanic system, N of Askja and SE of Myvatn lake, includes the central Ketildyngja shield volcano and the Sveinar fissure swarm that extends 130 km to the north coast of Iceland. The Kerlingardyngja shield volcano to the south is early Holocene. The latest eruption produced the Burfellshraun lava flow about 3,200 years ago that covered 75 km2.
