There are too many presumed extinct or now inactive volcanic features to list all of these below, so most monogenetic volcanoes can not be mentioned individually. This list of volcanoes in Iceland only includes major active and dormant volcanic mountains, of which at least 18 vents have erupted since human settlement of Iceland began around 900 AD.

Iceland experiences frequent volcanic activity, due to its location both on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and being over a hotspot.Nearly thirty volcanoes are known to have erupted in the Holocene epoch; these include Eldgjá, source of the largest lava eruption in human history.
Alongside the volcanoes exist numerous glaciers such as Vatnajökull, Mýrdalsjökull, and Eyjafjallajökull. Basalt columns and black sand beaches are examples of the volcanic activity of the area. The area also contains mountain ranges and Iceland's highest peak, Hvannadalshnjúkur, as well as the Vestmannaeyjar (Westman Islands) archipelago.
The geological configuration, along with the presence of nearby subglacial volcanoes such as Bárðarbunga and Grímsvötn, is responsible for the risk of jökulhlaups, which have affected Holuhraun repeatedly. The eruption in Holuhraun on 4 September 2014 Lava fountains of the fissure eruption in Holuhraun on 13 September 2014 around 21:20.
English: Map showing the Mid-Atlantic Ridge splitting Iceland and separating the North American and Eurasian Plates. The map also shows Reykjavik, the capital of Iceland, the Thingvellir area, and the locations of some of Iceland's active volcanoes (red triangles), including Krafla.
The Hofsjökull central volcano caldera is located under the south-west portion of the icecap and is 6–7 km (3.7–4.3 mi) wide and about 600 m (2,000 ft) deep. [11] Nunataks exposed on the caldera rim are 1,628 m (5,341 ft) high but probable rim height is about 1,650 m (5,410 ft) from subglacial mapping that also reveals a maximum thickness ...
Hofsjökull, subglacial volcano is a shield type with caldera, formed during the Last Glacial Period. The Hofsjökull glacier is the third largest ice cap after Vatnajökull and Langjökull. The largest active volcano in the country, situated in the west of the Highlands [32] [33] See chronology below: Hofsjökull 2,500,000-11,000, Hofsjökull 2015
