Stora-Viti crater, seen here from the SE, caps the low, 564-m-high Theistareykjarbunga shield volcano, the northernmost subaerial volcanic system along the eastern volcanic zone of Iceland. The Holocene Theistareykjarbunga shield volcano and its associated N-S fissure system extend from north of Myvatn lake to the northern coast of Iceland. The youngest dated eruption produced the Theistareykjahraun lava flow about 2700 years ago.

The small Litla-Viti pit crater (left) lies immediately SSW of Stora-Viti crater (right) at the summit of the very low-angle Theistareykjarbunga shield volcano. The low, 564-m-high shield volcano is part of the northernmost subaerial volcanic system of Iceland's eastern volcanic zone.

An aerial view from the north shows features of the Theistareykjabunga and Krafla volcanic systems. The very-low-relief Theistareykjabunga volcano, capped by the summit craters of Stora-Viti and Litla-Viti, appears at the lower left. The topographically indistinct Krafla caldera (center) is cut by prominent fissure swarms. The flat, mesa-like areas at the right and other topographically prominent features throughout the photo are table mountains and ridges formed during Pleistocene subglacial eruptions.
