Lake Mývatn was created about 2300 years ago by a large fissure eruption pouring out basaltic lava. The lava flowed down the valley to the lowland plain where it entered the Arctic Ocean about 50 km away.
The Mývatn district lies on the border of the volcanic zone which cuts across Iceland from north to south and is an extension of the Mid-Atlantic Ridge.
All geological formations are quite recent, dating from the Ice Age and postglacial times.
