About Theistareykir

The Holocene Theistareykir fissure system, including the basaltic Theistareykjarbunga shield volcano, extends from north of Myvatn lake to the coast of Iceland. This is the northernmost subaerial volcanic system along the Eastern Volcanic Zone of Iceland. The 30 km3 Theistareykjarbunga shield volcano formed slightly after deglaciation; the youngest dated eruption produced the Theistareykjahraun lava flow about 2,400 years ago.
