The Brennisteinsfjöll volcanic system, located east of Kleifarvatn lake, consists of a series of NE-SW-trending crater rows and small shield volcanoes.

Background:

Postglacial and historical basaltic lavas cover a wide area. An eruption in 1000 AD was dated by its occurrence at the time of a meeting of the Icelandic outdoor parliament at Thingvellier. The most recent eruption at Brennisteinsfjöll took place in the 14th century.
