Hofsjökull From Nýi-Dalur July 2005
__NOTOC__ Hofsjökull (Icelandic language, Icelandic: "temple glacier", ) is the third largest ice cap in Iceland after Vatnajökull and Langjökull and the largest active volcano in the country. It is situated in the west of the Highlands of Iceland and north of the mountain range Kerlingarfjöll, between the two largest glaciers of Iceland. It covers an area of 925 km2, reaching at its summit. The subglacial volcano is a shield volcano, shield type with caldera. Hofsjökull is the source of several rivers including the Þjórsá, Iceland's longest river. In the southeast of Iceland, between the easternmost glacier tongue of Vatnajökull (Axajökull) and Þrándarjökull, there is a smaller glacier (area about 4 km2), which is also called Hofsjökull. In 2015, Hofsjökull increased in mass, the first time in 20 years this had happened.

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 ...

Subglacial Volcano
A subglacial volcano, also known as a glaciovolcano, is a volcanic form produced by subglacial eruptions or eruptions beneath the surface of a glacier or ice sheet which is then melted into a lake by the rising lava. Today they are most common in Iceland and Antarctica; older formations of this type are found also in British Columbia and Yukon Territory, Canada. During the eruption, the heat of the lava from the subglacial volcano melts the overlying ice. The water quickly cools the lava, resulting in pillow lava shapes similar to those of underwater volcanoes. When the pillow lavas break off and roll down the volcano slopes, pillow breccia, tuff breccia, and hyaloclastite form. The meltwater may be released from below the ice as happened in Iceland in 1996 when the Grímsvötn caldera erupted, melting 3 km3 of ice and giving rise to a large glacial lake outburst flood. The shape of subglacial volcanoes tends to be quite characteristic and unusual, with a flatten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shield Volcanoes Of Iceland
A shield is a piece of personal armour held in the hand, which may or may not be strapped to the wrist or forearm. Shields are used to intercept specific attacks, whether from close-ranged weaponry or projectiles such as arrows, by means of active blocks, as well as to provide passive protection by closing one or more lines of engagement during combat. Shields vary greatly in size and shape, ranging from large panels that protect the user's whole body to small models (such as the buckler) that were intended for hand-to-hand-combat use. Shields also vary a great deal in thickness; whereas some shields were made of relatively deep, absorbent, wooden planking to protect soldiers from the impact of spears and crossbow bolts, others were thinner and lighter and designed mainly for deflecting blade strikes (like the roromaraugi or qauata). Finally, shields vary greatly in shape, ranging in roundness to angularity, proportional length and width, symmetry and edge pattern; differen ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland Plume
The Iceland hotspot is a hotspot (geology), hotspot which is partly responsible for the high volcanic activity which has formed the Iceland Plateau and the island of Iceland. Iceland is one of the most active volcano, volcanic regions in the world, with eruptions occurring on average roughly every three years (in the 20th century there were 39 volcanic eruptions on and around Iceland). About a third of the basaltic lavas erupted in recorded history have been produced by Icelandic eruptions. Notable eruptions have included that of Eldgjá, a fissure of Katla volcano, Katla, in 934 (the world's largest basaltic eruption ever witnessed), Laki in 1783 (the world's second largest), and several eruptions beneath ice caps, which have generated devastating Jökulhlaup, glacial bursts, most recently in 2010 after the eruption of Eyjafjallajökull. Iceland's location astride the Mid-Atlantic Ridge, where the Eurasian Plate, Eurasian and North American Plates are moving apart, is partl ...

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 ...

Þjórsá
Þjórsá () is Iceland's longest river at 230 kilometers (about 143 miles). It is in the south of the island. Þjórsá is a glacier river and has its source on the glacier Hofsjökull. It flows out through narrow gorges in the highlands of Iceland. Further downstream, another river, the Tungnaá, flows into it (see also Háifoss), before it enters the lowlands. There it passes the valley of Þjórsárdalur (Thjorsardalur) where the historical farm of Stöng is located. In the lowlands it flows along the eastern border of the Great Þjórsá Lava. In the middle of the now rather wide river, there is a big island called ''Árnes'', where there used to be a '' Þing''. The administrative unit of Árnessýsla was named after it. The ''hringvegur'' (Road No.1) traverses the river via a bridge between Selfoss and Hella. Some kilometers to the southwest the river flows into the Atlantic Ocean. 'Á' signifies river while 'þjór' means bull and is cognate to Danish - tyr, Swedish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerlingarfjöll
Kerlingarfjöll () is a tall mountain range in Iceland situated in the Highlands of Iceland near the Kjölur highland road. They are part of a large tuya volcano system of . The volcanic origin of these mountains is evidenced by the numerous hot springs and rivulets in the area, as well as red volcanic rhyolite stone of which the mountains are composed. Minerals that have emerged from the hot springs also color the ground yellow, red and green. The area was known formerly for its summer ski resort, but this was dismantled in 2000. Since 2000, Kerlingarfjöll has been operated as a highland resort, offering accommodation and food services to guests in the area. On March 17 in 2017 the ''Iceland Monitor'' stated that the Kerlingarfjöll Mountains and geothermal area were being turned into a nature reserve. Although parts of the place already had protection, the whole 367 square kilometres are to be under the protection of the state of Iceland. There have been thoughts of using the ...
