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 ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Area
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape A shape or figure is a graphics, graphical representation of an object or its external boundary, outline, or external Surface (mathematics), surface, as opposed to other properties such as color, Surface texture, texture, or material type. A pl ... or planar lamina, while ''surface area'' refers to the area of an open surface or the boundary (mathematics), boundary of a solid geometry, three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a plane curve, curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

Snæfellsjökull
Snæfellsjökull (, ''snow-fell glacier'') is a 700,000-year-old glacier-capped stratovolcano in western Iceland. It is situated on the westernmost part of the Snæfellsnes peninsula in Iceland. Sometimes it may be seen from the city of Reykjavík over Faxa Bay, at a distance of 120 km. The mountain is one of the most famous sites of Iceland, primarily due to the novel ''Journey to the Center of the Earth'' (1864) by Jules Verne, in which the protagonists find the entrance to a passage leading to the center of the earth on Snæfellsjökull. The mountain is included in the Snæfellsjökull National Park (Icelandic: ''Þjóðgarðurinn Snæfellsjökull''). Snæfellsjökull was visible from an extreme distance due to an arctic mirage on July 17, 1939. Captain Robert Bartlett of the ''Effie M. Morrissey'' sighted Snæfellsjökull from a position some distant. In August 2012, the summit was ice-free for the first time in recorded history. Geology The stratovolcano, which i ...

Torfajökull
Torfajökull ( Icelandic for "Torfi's glacier"; ) is a rhyolitic stratovolcano, caldera (central volcano) and complex of subglacial volcanoes, located north of Mýrdalsjökull and south of Þórisvatn Lake, Iceland. Torfajökull last erupted in 1477 and consists of the largest area of silicic extrusive rocks in Iceland. The volcano's eruption around 870, a combined bimodal eruption (rhyolite-basalt) with additional engagement of the Bárðarbunga-Veiðivötn volcanic system, has left a thin layer of easily recognized mixed tephra all over Iceland ( Landnámslag). This layer makes it possible to determine the exact dates of many archeological finds by so called tephrochronology, like in the Reykjavík 871±2 museum. Naming According to legend, the glacier is named for Torfi Jónsson í Klofa, an Icelandic historical figure. When the plague arrived in Iceland in 1493, Torfi fled with his family and his belongings into the highlands and settled in a valley surrounded by the glac ...

Tindfjallajökull
Tindfjallajökull () is a stratovolcano in the south of Iceland. It has erupted rocks of basaltic to rhyolitic composition, and a 5-km-wide caldera was formed during the eruption of the 54,000-year-old Thórsmörk Ignimbrite. It is capped by a glacier of 19 km².National Land Survey of Iceland (Icelandic) Its highest peak is Ýmir (1462m), /ref> which takes its name from the giant Ýmir of Norse mythology.

Eiríksjökull
Eiríksjökull ( Icelandic for "Eirík's glacier", ) is a glacier north-west of Langjökull in Iceland, with an area of reaching a height of , making it the largest table mountain in Iceland. Rising over above its surrounding, the lowest of a hyaloclastite (móberg) tuya formed presumably by a single subglacial volcanic activity is capped by a thick lava shield A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the mo .... It is currently dormant or extinct in terms of volcanic activity. Etymology The glacier was called Baldjökull until about 1700 and with relative certainty the current name is influenced by the nearby mountain Eiríksgnípa. Nothing is known with certainty about said Erik but a fable tells of an outlaw named Eiríkur or Eirekur who evaded capture by running into that m ...

Þórisjökull
Þórisjökull or Thórisjökull (, Icelandic for "Thóris's glacier") is a small glacier and volcano in western-central Iceland, to the southwest of Langjökull glacier. It has an elevation of . Kaldidalur lies in the foreground. Position þórisjökull is situated between Langjökull glacier and the shield volcano Ok to its east. The "Cold valley" (translation of Kaldidalur) is lying between them with its famous highland road of the same name. The volcano The glacier volcano Þórisjökull is a tuya from the Ice Age (in Iceland from 100,000 years ago til about 10,000 years ago). Its mountain part consists mainly of hyaloclastites. The glacier was part of Langjökull glacier probably til the end of the 18th century. Some geological research was made again on the Þórisjökull and Prestahnúkur area in 2009 and it shows clearly active volcanic fissures under the glacier which are part of the Prestahnúkur volcanic system (see weblink, Icelandic Meteorological Institute).

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
