Mýrdalsjökull
Mýrdalsjökull (pronounced , Icelandic for "(the) mire dale glacier" or "(the) mire valley glacier") is an ice cap in the south of Iceland. It is to the north of Vík í Mýrdal and to the east of the smaller ice cap Eyjafjallajökull. Between these two glaciers is Fimmvörðuháls pass. Its peak reaches in height and in the year 1980 it covered an area of approximately . The icecap of the glacier covers an active volcano called Katla. The caldera of the volcano has a diameter of and the volcano erupts usually every 40–80 years. The last eruption took place in 1918. Scientists are actively monitoring the volcano, particularly after the eruption of nearby Eyjafjallajökull began in April 2010. Since the year 930, 16 eruptions have been documented. The Eldgjá, a volcanic eruption fissure about long, which erupted in the year 936, is part of the same volcanic system. Before the Hringvegur (the main ring road round the island) was built, people feared traversing the pl ...

Katla (volcano)
Katla () is a large volcano in southern Iceland. It is very active; twenty eruptions have been documented between 930 and 1918, at intervals of 20–90 years. It has not erupted violently for years, although there may have been small eruptions that did not break the ice cover, including ones in 1955, 1999, and 2011. Prior eruptions have had a Volcanic Explosivity Index (VEI) of between 4 and 6 on a scale of 0 to 8. In comparison, the Eyjafjallajökull 2010 eruption had a VEI of 4. Bigger VEI-5 eruptions are comparable to Mount St. Helens 1980 eruption, while significantly rarer VEI-6 eruptions would be comparable to Krakatoa's 1883 eruption and Mount Pinatubo's 1991 eruption. Katla is one of the largest volcanic sources of carbon dioxide (CO2) on Earth, accounting for up to 4% of total global volcanic carbon dioxide emissions. Geography and physical appearances Katla is one of the largest volcanoes in Iceland. It is situated to the north of Vík í Mýrdal and to the east ...

Eyjafjallajökull
Eyjafjallajökull (; ), sometimes referred to by the numeronym E15, is one of the smaller ice caps of Iceland, north of Skógar and west of Mýrdalsjökull. The ice cap covers the caldera of a volcano with a summit elevation of . The volcano has erupted relatively frequently since the Last Glacial Period, most recently in 2010, when, although relatively small for a volcanic eruption, it caused enormous disruption to air travel across northern and western Europe for a week. Geography Eyjafjallajökull consists of a volcano completely covered by an ice cap. The ice cap covers an area of about , feeding many outlet glaciers. The main outlet glaciers are to the north: Gígjökull , flowing into Lónið , and Steinholtsjökull , flowing into Steinholtslón . In 1967, there was a massive landslide on the Steinholtsjökull glacial tongue. On 16 January 1967 at 13:47:55 there was an explosion on the glacier. It can be timed because the seismometers at Kirkjubæjarklaustur monitor ...

Geography Of Iceland
Iceland ( ) is an island country at the confluence of the North Atlantic and Arctic oceans, east of Greenland and immediately south of the Arctic Circle, atop the constructive boundary of the northern Mid-Atlantic Ridge about from Scotland and from New York City. One of the world's most sparsely populated countries, Iceland's boundaries are almost the same as the main island – the world's 18th largest in area and possessing almost all of the country's area and population and also it is world's 9th largest island country. It is the westernmost European country and has more land covered by glaciers than in all of continental Europe. The total size is . It has an exclusive economic zone of . Statistics Iceland is an island country in Northern Europe, straddling the Eurasian and North American plates between the Greenland Sea and the North Atlantic Ocean, northwest of the British Isles. Extent (locations outside mainland in parentheses) :North: Rifstangi, 66°32′3" N ( ...

Glaciers Of Iceland
The glaciers and ice caps of Iceland cover 11% of the land area of the country (about 11,400 km² out of the total area of 103,125 km²) and have a considerable impact on its landscape and meteorology. Glaciers are also contributing to the Icelandic economy, with tourists flocking to the country to see glaciers on snowmobiles and on glacier hiking tours. However, the recent loss of ice due to climate change is an increasing concern in Icelandic society. Description An ice cap is a mass of glacial ice that covers less than 50,000 km² of land area covering a highland area and they feed outlet glaciers. Many Icelandic ice caps and glaciers lie above volcanoes, such as Grímsvötn and Bárðarbunga, which lie under the largest ice cap, Vatnajökull. The caldera of Grímsvötn is 100 km² in area, and Bárðarbunga is 60 km². When volcanic activity occurs under the glacier, the resulting meltwater can lead to a sudden glacial lake outburst flood, known in ...

Eldgjá
Eldgjá (, "fire canyon") is a volcano and a canyon in Iceland. Eldgjá is part of the Katla volcano; it is a segment of a long chain of volcanic craters and fissure vents that extends northeast away from Katla volcano almost to the Vatnajökull ice cap. This fissure experienced a major eruption around 939 Common Era, CE, which was the largest effusive eruption in recent history. It covered about of land with of lava from two major lava flows. While Icelandic records about the effects of the eruption are sparse, paleoclimate proxies and historical records from China, Europe and the Islamic World, Islamic world describe widespread impacts on the Northern Hemisphere climate. The Eldgjá eruption produced a noticeable cooling of the climate, with resulting cold winters and food crises across Eurasia. Geology The interaction between the Mid-Atlantic Ridge and the Iceland hotspot has given rise to the stack of volcanic rocks that forms Iceland. Volcanoes on Iceland occur in four ...

Vík í Mýrdal
The village of Vík (; or Vík í Mýrdal in full) is the southernmost village in Iceland, located on the main ring road around the island, around by road southeast of Reykjavík. Despite its small size (750 inhabitants in Mýrdalshreppur as of January 2021) it is the largest settlement for some around and is an important staging post, and thus it is indicated on road signs from a long distance away. It is an important service center for the inhabitants of and visitors to the coastal strip between Skógar and the west edge of the Mýrdalssandur glacial outwash plain. Overview In 1991, the US journal ''Islands Magazine'' counted the beach at Vík as one of the ten most beautiful beaches on Earth. Its stretch of black basalt sand is one of the wettest places in Iceland. The cliffs west of the beach are home to many seabirds, most notably puffins which burrow into the shallow soils during the nesting season. Offshore lie stacks of basalt rock, remnants of a once more extensive ...

Icelandic Language
Icelandic (; is, íslenska, link=no ) is a North Germanic language spoken by about 314,000 people, the vast majority of whom live in Iceland, where it is the national language. Due to being a West Scandinavian language, it is most closely related to Faroese, western Norwegian dialects, and the extinct language, Norn. The language is more conservative than most other Germanic languages. While most of them have greatly reduced levels of inflection (particularly noun declension), Icelandic retains a four- case synthetic grammar (comparable to German, though considerably more conservative and synthetic) and is distinguished by a wide assortment of irregular declensions. Icelandic vocabulary is also deeply conservative, with the country's language regulator maintaining an active policy of coining terms based on older Icelandic words rather than directly taking in loanwords from other languages. Since the written language has not changed much, Icelandic speakers can read classic ...

Jökulhlaup
A jökulhlaup ( ) (literally "glacial run") is a type of glacial outburst flood. It is an Icelandic term that has been adopted in glaciological terminology in many languages. It originally referred to the well-known subglacial outburst floods from Vatnajökull, Iceland, which are triggered by geothermal heating and occasionally by a volcanic subglacial eruption, but it is now used to describe any large and abrupt release of water from a subglacial or proglacial lake/reservoir. Since jökulhlaups emerge from hydrostatically sealed lakes with floating levels far above the threshold, their peak discharge can be much larger than that of a marginal or extra-marginal lake burst. The hydrograph of a jökulhlaup from Vatnajökull typically either climbs over a period of weeks with the largest flow near the end, or it climbs much faster during the course of some hours. These patterns are suggested to reflect channel melting, and sheet flow under the front, respectively. Similar pr ...

Fimmvörðuháls
Fimmvörðuháls (; "five cairns pass") is the area between the glaciers Eyjafjallajökull and Mýrdalsjökull in southern Iceland. The route between Skógar and Thórsmörk goes through this pass and is one of the most popular walking routes in Iceland, despite being long and involving of climbing. There are two mountain huts along Fimmvörðuháls, one owned by hiking association Útivist, the other called Baldvinsskáli (). The route from Skógar has many waterfalls along the way. The route is only accessible between mid-June and late-August. On the night of 16 May 1970, three travellers died in the mountain pass in a snowstorm. Hiking the Fimmvörðuháls mountain pass takes 1–2 days. It is also possible to combine the Fimmvörðuháls route with the Laugavegur Trek between Landmannalaugar and Thórsmörk to make a trip of 4–6 days in length. 2010 eruption On 20 March 2010, an eruption of the Eyjafjallajökull volcano began in Fimmvörðuháls following mont ...

Volcanism Of Iceland
:''The volcano system in Iceland that started activity on August 17, 2014, and ended on February 27, 2015, is Bárðarbunga.'' :''The volcano in Iceland that erupted in May 2011 is Grímsvötn.'' Iceland experiences frequent volcanic activity, due to its location both on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and over a hot spot. Nearly thirty volcanoes are known to have erupted in the Holocene epoch; these include Eldgjá, source of the largest lava eruption in human history. Volcanic systems and volcanic zones of Iceland Holocene volcanism in Iceland is mostly to be found in the ''Neovolcanic Zone'', comprising the Reykjanes Volcanic Belt (RVB), the West Volcanic Zone (WVZ), the Mid-Iceland Belt (MIB), the East Volcanic Zone (EVZ) and the North Volcanic Zone (NVZ). Two lateral volcanic zones play a minor role: Öræfi Volcanic Belt (ÖVB) and Snæfellsnes Volcanic Belt (SVB). Outside of the main island are the Reykjanes Ridge (RR), as part of the Mid-At ...

List Of Volcanoes In Iceland
This list of volcanoes in Iceland includes active and dormant volcanic mountains, of which 18 have erupted since human settlement of Iceland began around 900 AD. __TOC__ List Volcanic zones and systems Iceland has four major volcanic zones surrounding an hypothetical hotspot: * the Reykjanes zone (RVZ), subdivided into the Reykjanes Ridge (RR) (the Mid-Atlantic Ridge South of Iceland) and the Reykjanes Volcanic Belt (RVB) (on the main island); * the West Volcanic Zone (WVZ); * the East Volcanic Zone (EVZ) (extended to the Westman Islands, South of the main island); * the North Volcanic Zone (NVZ). The Mid-Iceland Belt (MIB) connects them across central Iceland. In Iceland's East Volcanic Zone (EVZ), the central volcanoes, Vonarskarð and Hágöngur belong to the same volcanic system; this also applies to Bárðarbunga and Hamarinn, and to Grímsvötn and Þórðarhyrna. North of Iceland, the Mid-Atlantic Ridge is called Kolbeinsey Ridge (KR) and is connected to the No ...
