Fagradalsfjall (Icelandic pronunciation: [ˈfaɣratalsˌfjatl̥]) is a shield volcano and tuya with multiple prominences located on the Reykjanes Peninsula, around 40 kilometres (25 mi) from Reykjavík. A volcanic eruption began on 19 March 2021 in Geldingadalir to the south of Fagradalsfjall, which is still ongoing.
The name is a compound of the Icelandic words fagur ("beautiful"), dalur ("valley") and fjall ("mountain").
Tectonic setting
Fagradalsfjall is a vent of the Krýsuvík-Trölladyngja volcanic system in the Southern Peninsula. It is situated within a zone of active rifting in a divergent boundary between the Eurasian and North American plates.
2020–21 activity at Geldingadalir
Beginning December 2019 and into March 2021, a swarm of earthquakes, two of which reached a magnitude of 5.6, rocked the Reykjanes Peninsula, sparking concerns that an eruption was imminent. The earthquakes were thought to have been triggered by dyke intrusions and magma moving under the peninsula. Minor damage to homes were reported by the 5.6 earthquake on February 4. In the past three weeks, more than 40,000 tremors have been recorded by seismographs.
Eruption south of Fagradalsfjall
On March 19 2021, an effusive eruption started just before 9:30 pm local time in Geldingadalir to the south of Fagradalsfjall, the first known eruption on the peninsula in about 800 years. Fagradalsfjall has been dormant for 6,000 years. The eruptive activity was first announced by the Icelandic Meteorological Office at 9:40 pm. Reports stated a 600–700-metre-long (2,000–2,300 ft) fissure vent began ejecting lava, which covered an area of less than 1 square kilometre (0.39 sq mi). As of the following day, the lava flows posed no threat to residents, as the area is mostly uninhabited, although there is potential for sulfur dioxide pollution.
Accident
On May 3, 1943, LTG Frank Maxwell Andrews, a US Army senior officer and founder of the United States Army Air Forces, along with fourteen others were killed when their B-24 aircraft Hot Stuff crashed into the side of the volcano.
