The Strockur geyser is a prominent feature of the Geysir geothermal field, located south of Hveravellir central volcano. The volcano lies beneath the Langjökull icecap at the northern end of an active volcanic zone that extends to the NE from the Reykjanes Peninsula. Several shield volcanoes have been constructed along flank fissure zones, and postglacial lava flows flank Langjökull on the northern, western, and eastern sides. The massive Hallmundahraun lava flow, which covers 200 sq km, was erupted shortly after 900 CE.
