There are about 32 volcanic systems in Iceland. Volcanic system means a volcano-tectonic fissure system and – very often a bigger volcano, a so-called central volcano which in most cases is a stratovolcano and may contain a caldera.[2][3]
Askja
- Askja; An active volcano in the central highlands. A complex of nested calderas within the Dyngjufjöll mountains. The Askja system includes, for example, the Herðubreið tabular volcano, the Herðubreiðartögl palagonite ridge and the shield volcanoes Kollóttadyngja, Flatadyngja and Svartadyngja. (Part of the North volcanic zone (NVZ)).

Bárðarbunga
- Bárðarbunga; An active stratovolcano located under the Vatnajökull glacier. The second highest mountain in Iceland, 2,009 metres (6,591 ft) above sea level, and part of a volcanic system that is approximately 200 kilometres (120 mi) long and 25 kilometres (16 mi) wide. Historically there are large eruptions every 250–600 years. Part of the East volcanic zone (EVZ).
See Chronology of Eruptions below: Bárðarbunga ca.6600-6700 BC, Bárðarbunga 877, Bárðarbunga 1477, Bárðarbunga 1701-1864, Bárðarbunga 1910, Bárðarbunga 1996, Bárðarbunga 2010, Bárðarbunga 2014-15.[4]
Brennisteinsfjöll
- Brennisteinsfjöll; A minor system on the Reykjanes Peninsula in the southwest. crater rows and small shield volcanoes. Part of the Reykjanes volcanic zone (RVZ).
See Chronology of Eruptions below: Brennisteinsfjöll 5200BP, Brennisteinsfjöll 1340, Brennisteinsfjöll 1341
Dyngjufjöll
- Dyngjufjöll, a volcanic mountain range in the northeast of Iceland. It belongs to the Askja volcanic system or the volcanic system, (sometimes called the (Dyngjufjöll volcanic system), and is part of the Vatnajökull National Park. The central volcano of basalt and rhyolite has its own system of crevices and fissures, which last erupted in 1961. (Part of the North volcanic zone (NVZ)).
See Chronology of Eruptions below: Dyngjufjöll 1961,
Eldey
- Eldey a small island about 13 kilometres off the coast of the Reykjanes Peninsula in south west. The Eldey and Geirfuglasker volcanic systems together form the 35–40 km (20 to 25 mile) long Eldey system on the mid-Atlantic ridge. There is not a central volcano.[5]
See Chronology of Eruptions below:[example needed]
Eldfell
- Eldfell, a volcanic cone on the island of Heimaey. It formed in a volcanic eruption which began without warning on the eastern side of Heimaey, in the Westman Islands, on 23 January 1973. The eruption caused a major crisis for the island and led to its temporary evacuation. Volcanic ash fell over most of the island, destroying around 400 homes, and a lava flow threatened to close off the harbour, the island's main income source via its fishing fleet. An operation was mounted to cool the advancing lava flow by pumping sea water onto it, which was successful in preventing the loss of the harbour. Part of the East volcanic zone (EVZ).
See Eruptive Chronology below: Eldfell 1973
Eldgjá
- Eldgjá, a volcano and a canyon that is part of the Katla volcano; a segment of a 40 kilometres (25 mi) chain of volcanic craters and fissure vents that extends northeast away from Katla. Part of the East volcanic zone (EVZ).
See Chronology of Eruptions below: Eldgjá 934 or 939
Esja / Esjan
- Esja, (Esjan), a 914 m (2,999 ft) mountain situated in the south-west of Iceland, about ten kilometres north of Iceland's capital city Reykjavík. Esja is not a single mountain, but a volcanic mountain range, made from basalt and tuff. Esja was built up at the end of the Pleistocene with the beginning of the Ice Age. During the warm periods lava flowed, and in the cold periods ridges of tuff were built up under the glacier. The western part of the mountain range is the oldest (about 3.2 million years) and the eastern part is the youngest (about 1.8 million years).[6] Part of the Reykjanes volcanic zone (RVZ).
See Chronology of Eruptions below: Ezjá 3,200,000, Ezjá 1,800,000
Esjufjöll
- Esjufjöll, subglacial volcano at the SE part of the Vatnajökull icecap. A strict nature reserve.[7] The volcanic system consists of the Snaehetta central volcano with a large caldera. Most of the volcano, including the 40 km2 caldera, is covered by the icecap. On the other hand, are parts of the SE flank exposed in NW-SE-trending ridges.[8] Most of the exposed rocks are mildly alkaline basalts, but there are also small amounts of rhyolitic rocks.[8] Part of the East volcanic zone (EVZ) (or Oræfi Volcanic Belt.[9][10])
See Chronology of Eruptions below:[example needed]
Eyjafjallajökull
- Eyjafjallajökull, (E15),[11] An ice cap covers the caldera, erupts relatively frequently since the Last Glacial Period, most recently in 2010 disrupting international travel.[12][13] Part of the East volcanic zone (EVZ).
See Chronology of Eruptions below: Eyjafjallajökull 1612, Eyjafjallajökull 1821-23, Eyjafjallajökull 2010 March, Eyjafjallajökull 2010 April

- Fagradalsfjall; is an active tuya volcano formed in the Last Glacial Period on the Reykjanes Peninsula,[14][15] around 40 kilometres (25 mi) from Reykjavík.[16] 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 Svartsengi and Krýsuvík systems.[17] No volcanic eruption had occurred for 815 years on the Reykjanes Peninsula until 19 March 2021. Part of the Reykjanes volcanic zone (RVZ).
See Chronology of Eruptions below: Fagradalsfjall 2021, Fagradalsfjall 2022, Fagradalsfjall 2023
Festarfjall
- Festarfjall, an exposed tuya mountain on the south coast of the Reykjanes Peninsula near the Fagradalsfjall volcanic system and Grindavík. The flat topped volcano formed under the ice-sheet in the Last Glacial Period on the Reykjanes Peninsula,[14] It has been bisected vertically by coastal erosion, to expose its inner structure, including lava layers and an intrusive magma dyke. It may have been formed during two separate glacial periods.[14] Part of the Reykjanes volcanic zone (RVZ). [example needed]
Fremrinámur
- Fremrinámur, A volcanic system on the basalt plateau, at the junction of the Mid-Atlantic Ridge and the Greenland–Iceland–Faeroe Ridge.[18] (Part of the North volcanic zone (NVZ)).
See Chronology of Eruptions below: Fremrinámur 800 BC.
Geirfuglasker
- Geirfuglasker ("Great Auk Rock") was a small islet near Reykjanes, Iceland, a volcanic rock with steep sides except for two landing places. It submerged beneath the waves in 1830, due to a volcanic eruption. Later a new Geirfuglasker appeared on the site.[19] (Part of the Reykjanes volcanic zone (RVZ)).
See Chronology of Eruptions below: Geirfuglasker 1830.
Gjálp
Gjálp is a hyaloclastite ridge (tindar) under the Vatnajökull glacier shield. It originated in an eruption series in 1996 which is probably part of the Grímsvötn volcanic system,[20][21]
It was the first modern technical monitoring and analysis of a subglacial eruption under a thick ice cover with a resulting jökulhlaup.[22][23] The volume of meltwater was around 4 km3.[24] The Vatnajökull glacier is part of the East volcanic zone (EVZ).
See Chronology of Eruptions below: Gjálp 1938, Gjálp 1996.
Grensdalur
- Grensdalur; is a volcano that was active during Pleistocene. Part of the South Iceland Seismic Zone (SISZ).
See Chronology of Eruptions below: Grensdalur 2,500,000
Grímsey
- Grímsey, is a small Icelandic island, 40 kilometres (20 nautical miles) off the north coast of the main island of Iceland, where it straddles the Arctic Circle.[25] (However, due to long-term oscillations in the Earth's axis, the Arctic Circle is shifting northward by about 14.5 metres (48 ft) per year (varying substantially from year to year due to the complexity of the movement). As of 2020, the place where the line crosses the island is close to the northern tip and by the middle of the 21st century it will pass north of Grimsey altogether.) Part of the Kolbeinsey Ridge (KR).
See Chronology of Eruptions below: [example needed]
Grímsnes
- Grímsnes, is a fissure or crater row volcanic system. Part of the South Iceland Seismic Zone (SISZ).
See Chronology of Eruptions below: Grímsnes 3500 BC.
Kerið
- Kerið is a volcanic crater lake located in the Grímsnes area in south Iceland, along the Golden Circle. It is one of several crater lakes in the area, known as the Western Volcanic Zone, created as the land moved over a localized hotspot, but it has the most visually recognizable caldera still intact. The caldera, like the other volcanic rock in the area, is composed of a red (rather than black) volcanic rock, and is approximately 55 m (180 ft) deep, 170 m (560 ft) wide, and 270 m (890 ft) across. Kerið's caldera is one of the three most recognisable volcanic craters because at approximately 6,500 years old, it is only half the age of most of the surrounding volcanic features. The other two are Seyðishólar and Kerhóll.
Although originally believed to have been formed by a volcanic explosion, studies of the Grímsnes region failed to find any supporting evidence. So it is now believed that Kerið was a cone volcano which erupted and emptied its magma reserve. Once the magma was depleted, the weight of the cone collapsed into the empty magma chamber. The current pool of water at the bottom of the crater is at the same level as the water table and is not caused by rainfall.[26]
See Chronology of Eruptions below: Kerið 6,500 BP.
Grímsvötn
- Grímsvötn; an active volcano with a (partially subglacial) fissure system located in Vatnajökull National Park. Including the Skaftá eruption of 1783, Grímsvötn is probably the most eruptive volcano system in Iceland. The Laki/Lakagígar lava field alone is estimated to have produced about 15 cubic kilometres (3.6 cu mi) of lava. Grímsvötn has probably had more than 30 eruptions in the last 400 years, and produced around 55 cubic kilometres (13 cu mi) over the last 10,000 years.[1] Part of the East volcanic zone (EVZ).
See Chronology of Eruptions below: Grímsvötn 8230 BC, Grímsvötn 753, Grímsvötn 781, Grímsvötn 1332, Grímsvötn 1341, Grímsvötn 1354, 1598, 1603, 1619, 1629, 1638, 1659, 1684-85, 1774, 1783-84, 1797, 1807, 1816, 1854, 1861, 1867, 1873, 1883, 1885, 1887, 1889, 1892, 1897, 1902-04, 1905-06, 1908-09, 1910, 1922, 1923, 1933, 1938, 1941, 1945, 1954, 1983, 1984, 1996, 1998, 20 04, 2011.

See Chronology of Eruptions below: Hverfjall 500 BC
Iceland hotspot
- Iceland hotspot; a hotspot which is partly responsible for the high volcanic activity which has formed the Iceland Plateau and the island of Iceland. Iceland's location astride the Mid-Atlantic Ridge, where the Eurasian and North American Plates are moving apart, is partly responsible for this intense volcanic activity, but an additional cause is necessary to explain why Iceland is a substantial island while the rest of the ridge mostly consists of seamounts, with peaks below sea level.
As well as being a region of higher temperature than the surrounding mantle, the hotspot is believed to have a higher concentration of water. The presence of water in magma reduces the melting temperature, which may also play a role in enhancing Icelandic volcanism.
Ingólfsfjall
- Ingólfsfjall; A tuya in the vicinity of Hveragerði originating from subglacial eruptions and consisting mostly of basalt and palagonite.[37] Part of the South Iceland Seismic Zone (SISZ).

Kolbeinsey
- Kolbeinsey, is a small basalt islet, devoid of vegetation, in the Greenland Sea located 105 kilometres (55 nautical miles) off the northern coast of Iceland, 74 km (40 nmi) north-northwest of the island of Grímsey. It is the northernmost point of Iceland and lies north of the Arctic Circle.[43] Kolbeinsey is subject to rapid wave erosion and is expected to disappear in the near future. Erosion rate data from 1994 suggested that this would happen around 2020.[44] As of April 2021[update], two small skerries remained visible at low tide.[45][46]
Kolbeinsey is the only sub-aerial expression of this portion of the Mid-Atlantic Ridge. It formed during the late-Pleistocene (from circa 2.58 million to 11,700 years ago.) (or Holocene). Dredged glass shards indicate submarine eruptive activity during the late-Pleistocene until at least 11,800 radiocarbon years ago.[47] Part of the Kolbeinsey Ridge (KR).

Common era (CE), Anno Domini (AD)
- 150 AD ± 75 years[72] - Hengill, Fissure vent eruption.[136] (Part of the West volcanic zone (WVZ))
- Circa 50-350 CE Snæfellsjökull, The latest eruption took place circa 50-350 CE and released approximately 0.11 km3 (144,000,000 cu yd) of volcanic material. The eruption was explosive and originated from the summit crater, and may have produced lava flows.[137][138] (Part of the Snæfellsnes volcanic belt (SVB))
- Note. The Volcanic winter of 536 was the most severe and protracted episode of climatic cooling in the Northern Hemisphere in the last 2,000 years.[139] The source of the eruption remains to be found. Icelandic volcanos were proposed.[93][140] However, the cryptotephras dated exactly to AD 536 are geochemically distinct from Icelandic tephra,[141] and the shards in the Swiss glacier have large age uncertainty.[93]

Iceland has several major volcanic zones surrounding the Iceland hotspot:
East volcanic zone (EVZ)
The East Volcanic Zone (EVZ), the central volcanoes Vonarskarð and Hágöngur, belong to the same volcanic system.[191] The southern propagating rift region of the EVZ with more tendency yo explosive eruption characteristics is known as the Southern Iceland Volcanic Zone (SIVZ).[62]
Includes: Bárðarbunga, Bláhnjúkur, Brennisteinsalda, Eldgjá, Eyjafjallajökull, Gjálp, Grímsvötn, central volcano Hágöngur (is: Hágöngur), Hekla, Katla, Lakagigar, Laki, Þjórsá Lava, Þórólfsfell, Surtsey, Thordarhyrna (Þórðarhyrna), Tindfjallajökull, Torfajökull, Vatnafjöll, several volcanoes in Vatnajökull, Vatnaöldur, Vestmannaeyjar (Westman Islands), central volcano Vonarskarð.
Kolbeinsey Ridge (KR)
The Kolbeinsey Ridge is a segment of the Mid-Atlantic Ridge located to the north of Iceland in the Arctic Ocean. It is bounded to the south by the Tjörnes Fracture Zone, which connects the submarine ridge to the on-shore Northern Volcanic Zone rifting center in eastern Iceland.[48] The volcanic islands Kolbeinsey and Grímsey lie along the Kolbeinsey Ridge.
Mid-Iceland Belt (MIB)
The Mid-Iceland belt (MIB) connects the East, West and North volcanic zones, across central Iceland.
North volcanic zone (NVZ)
North of Iceland, the Mid-Atlantic Ridge is called Kolbeinsey Ridge (KR) and is connected to the North Volcanic Zone via the Tjörnes Fracture Zone (TFZ).
Includes: Askja, Dimmuborgir, Fremrinámur, Herðubreið, Hverfjall, Kollóttadyngja, Krafla, Kverkfjöll, many volcanoes in the Mývatn district, Rauðhólar, Theistareykjarbunga, Trölladyngja
Öræfajökull volcanic belt (ÖVB)
The Öræfajökull volcanic belt (ÖVB, also Öræfi volcanic belt) is an intraplate volcanic belt, connected to the Eurasian plate.[192][193]
Includes: Öræfajökull
Reykjanes volcanic zone (RVZ)
The Reykjanes volcanic zone (RVZ or Reykjanes volcanic belt, RVB) contains multiple fissure vent orientated volcanic systems including one with a similar name. It is the continuation of the Reykjanes Ridge (RR) (the Mid-Atlantic Ridge south of Iceland and intersects to its north-east at Hengill with the WVZ and the South Iceland seismic zone (SISZ, also known as the Reykjanes fracture zone, RFZ).
Includes: Bláfjöll, Brennisteinsfjöll, Búrfell (Hafnarfjörður), Eldborg í Bláfjöllum, Eldvörp–Svartsengi, Fagradalsfjall, Heiðin há, Helgafell (Hafnarfjörður), Hengill (also listed under WVZ), Keilir, Krýsuvík (volcanic system), Krýsuvík fires, Leitin, Rauðhólar (Reykjavík), Reykjanes volcanic system, Stóra-Eldborg undir Geitahlíð, Svartsengi Power Station, Sveifluháls, Vífilsfell, Þorbjörn (mountain)
Snæfellsnes volcanic belt (SVB)
The Snæfellsnes volcanic belt (SVB) is an intraplate volcanic belt, connected to the North American plate.[192]
It is proposed that the east–west line from the Grímsvötn volcano in the Mid-Iceland Belt (MIB) to the SVB shows the movement of the North American Plate over the Iceland hotspot.[194]
Includes: Snæfellsjökull and smaller volcanoes on Snæfellsnes, plus Helgafell.
South Iceland Seismic Zone (SISZ)
The South Iceland Seismic Zone (SISZ) is a fracture zone, which connects the East and West Volcanic Zones. It contains its own volcanic systems, smaller than those in the Mid-Iceland Belt. The SISZ is a set of major and active transform faults striking west-northwest in southwestern Iceland, being one of two large fracture zones, associated with such transform faults, striking about 75°N to 80°W, the other being the Tjörnes Fracture Zone.[85][86]
Includes: The towns of Selfoss, Vík, Hvolsvöllur and probably Þingvellir the old meeting place of the Alþing.
Tjörnes Fracture Zone (TFZ)
The Tjörnes Fracture Zone (TFZ) connects the North Volcanic Zone to the Kolbeinsey Ridge (KR), which is part of the Mid-Atlantic Ridge. It contains its own volcanic systems, which are smaller than those in the Mid-Iceland Belt.
It is one of two major and active transform faults zones striking west-northwest in northern and southern Iceland.[85] The Tjörnes and Reykjanes Fracture Zones are found striking about 75°N to 80°W.[86]
West volcanic zone (WVZ)
Includes: Geitlandsjökull, Geysir, Hengill (also listed under RFZ), Hlöðufell, Hveravellir, Skjaldbreiður, Stóra-Björnsfell, Þórisjökull.[195]
Eruptive activity
Grímsvötn eruptivity
Grímsvötn, including the Skaftá eruption of 1783, is probably the most eruptive volcano system. The Lakagígar lava field alone is estimated to have produced about 15 cubic kilometres (3.6 cu mi) of lava. Grímsvötn has probably had more than 30 eruptions in the last 400 years, and produced around 55 cubic kilometres (13 cu mi) over the last 10,000 years.[1] (Part of the East volcanic zone (EVZ)) See Grímsvötn index above.
Katla eruptivity
Katla has erupted 17 times in historical times, and Eldgjá seems to be part of the same system. The total volume of volcanic eruptions from Katla over the last 10,000 years is very similar to Grímsvötn.[1] (Part of the East volcanic zone (EVZ)). See Katla index above.
Hekla eruptivity
Hekla has erupted at least 17 times in historical times, with total volume about 7 cubic kilometres (1.7 cu mi), but around 42 cubic kilometres (10 cu mi) since the last ice age.[1] (Part of the East volcanic zone (EVZ)). See Hekla index above.
