The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

The Holocene Theistareykjarbunga basaltic shield volcano (also known as Theistareykir) and its associated N-S fissure system extends from north of Myvatn lake to the northern coast of Iceland. The low, 564-m-high Theistareykjarbunga shield volcano is the northernmost subaerial volcanic system along the eastern volcanic zone of Iceland. The Theistareykjarbunga segment is dominated by the 30 cu km Storaviti shield volcano, which was formed slightly after deglaciation. The youngest dated eruption produced the Theistareykjahraun lava flow about 3000-2700 years ago.
