Fagradalsfjall (Icelandic: [ˈfaɣraˌtalsˌfjatl̥] ⓘ) is an active tuya volcano formed in the Last Glacial Period on the Reykjanes Peninsula,[5][6] around 40 kilometres (25 mi) from Reykjavík, Iceland.[7] Fagradalsfjall is also the name for the wider volcanic system covering an area 5 kilometres (3 mi) wide and 16 kilometres (10 mi) long between the Eldvörp–Svartsengi [ˈɛltvœr̥p–ˈsvar̥(t)sˌeiɲcɪ] and Krýsuvík systems.[8] The highest summit in this area is Langhóll [ˈlauŋkˌhoutl̥] (385 m (1,263 ft)).[1] No volcanic eruption had occurred for 815 years on the Reykjanes Peninsula until 19 March 2021 when a fissure vent appeared in Geldingadalir to the south of Fagradalsfjall mountain.[9][10] The 2021 eruption was effusive and continued emitting fresh lava sporadically until 18 September 2021.[11]

The eruption was unique among the volcanoes monitored in Iceland so far and it has been suggested that it could develop into a shield volcano.[12][13] Due to its relative ease of access from Reykjavík, the volcano has become an attraction for local people and foreign tourists.[14][15] Another eruption, very similar to the 2021 eruption, began on 3 August 2022,[16] and ceased on 21 August 2022.[17] A third eruption appeared to the north of Fagradalsfjall near Litli-Hrútur [ˈlɪhtlɪ-ˌr̥uːtʏr̥] on 10 July 2023,[4][18] and ended on 5 August 2023.[19]
