Hveravellir (Icelandic pronunciation: ​[ˈkʰvɛːraˌvɛtlɪr̥]) is a central volcano, as well as a geothermal field of the Oddnýjarhnjúkur-Langjökull subglacial volcanic system in the north of Langjökull glacier.

Description[]

Hveravellir is located in west-central Iceland in the north of Langjökull glacier.[1] It is part of the Oddnýjarhnjúkur-Langjökull volcanic system.[2] The central volcano, Hveravellir, lies beneath a massive ice sheet to the east of Erikskökull.[1]

Northeast of the volcano, at the northern end of the Kjalhraun lava field, is the 2.5 km² Hveravellir geothermal field with numerous hot springs, fumaroles and hot mud.[2] The oldest mention of Hveravellir dates back to 1752 when Icelandic travelers Eggert Ólafsson (1726–1768) and Bjarni Pálsson (1719–1779) described the field in their travel report on the island.[3][4] The geothermal field is a tourist attraction; a bath can be taken in the pool created by damming the hot water stream in 1950.[3] Hveravellir was declared a natural monument.[5]
