Askja
Askja () is an active volcano situated in a remote part of the Highlands of Iceland, central highlands of Iceland. The name Askja refers to a complex of nested calderas within the surrounding Dyngjufjöll mountains, which rise to , ''askja'' meaning ''box'' or ''caldera'' in Icelandic. Location The region is only accessible for a few months of the year. Being situated in the rain shadow to the northeast of the Vatnajökull glacier, the area receives only about 450 mm of rainfall annually. NASA The area was used by NASA during training for the Apollo program to prepare astronauts for the lunar missions. Their main objective in Askja was to study geology. The Astronaut Monument in Húsavík lists the 32 astronauts who participated. Eruptions Askja was virtually unknown until the Sub-plinian eruptions, subplinian eruption which started on March 28, 1875, followed by the devastating phreatoplinian explosion on March 29, 1875.

Ingólfsfjall
Ingólfsfjall () is a tuya in Iceland in the vicinity of Hveragerði. Name The name is derived from Iceland's official first settler, Ingólfur Arnarson. The Medieval Landnámabók says that he passed here his third winter in Iceland after his arrival from Norway with his clan, and before his slaves found the columns of his high seat and he went to the region of Reykjavík to settle there. The source also states that the chief was buried within the small mound on top of Ingólfsfjall. Geology Ingólfsfjall consists mostly of basalt and palagonite and has its origin in subglacial eruptions which turned in the end subaerial and produced some lava at its top.Ari Trausti Guðmundsson, Pétur Þorleifsson: Íslensk Fjöll.

Surtsey
Surtsey ("Surtr's island" in Icelandic, ) is a volcanic island located in the Vestmannaeyjar archipelago off the southern coast of Iceland. At Surtsey is the southernmost point of Iceland. It was formed in a volcanic eruption which began below sea level, and reached the surface on 14 November 1964. The eruption lasted until 5 June 1967, when the island reached its maximum size of . Since then, wave erosion has caused the island to steadily diminish in size: , its surface area was . The most recent survey (2007) shows the island's maximum elevation at above sea level. The new island was named after Surtr, a fire ''jötunn'' or giant from Norse mythology. It was intensively studied by volcanologists during its eruption, and afterwards by botanists and other biologists as life forms gradually colonised the originally barren island. The undersea vents that produced Surtsey are part of the Vestmannaeyjar submarine volcanic system, part of the fissure of the sea floor called the ...

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 ...

Þjórsá Lava
The Great Þjórsá Lava ( Icelandic: ''Þjórsárhraunið mikla'' ) is the largest lava flow in Iceland (by both area and volume) and the largest lava that is known to have erupted in a single eruption in the Holocene. It belongs to a group of lavas known as the Tungnaá lavas. It was erupted in the Veiðivötn region, Central Iceland, 8600 years BP (6600 BC). The crater area is covered by younger lavas and eruptives. The Þjórsá Lava does not appear on the surface until 70 km downstream of its supposed crater area. In the lowlands of South Iceland the lava has overflown wide areas, covering the districts Landsveit, Gnúpverjahreppur, Skeið and Flói. The main rivers of South Iceland, Þjórsá and Hvítá/Ölfusá, stream along the borders of the lava to the east and west and the long beach between the river mouths is formed by the lava. The sea level seems to have been around lower than today when the lava was erupted. Along with the rising sea level the ocean has tr ...

Öræfajökull
Öræfajökull (; ' Öræfi glacier' or 'wasteland glacier') is an ice-covered volcano in south-east Iceland. The largest active volcano and the highest peak in Iceland at , it lies within the Vatnajökull National Park and is covered by part of the glacier. The original Norse settlers named the volcano Knappafellsjǫkull (Old Norse: ; Modern Icelandic: Hnappafellsjökull ; 'knobs mountain glacier'). The current name, ''Öræfajökull'', was eventually adopted after the 1362 eruption. Description Öræfajökull is located at the southern extremity of the Vatnajökull glacier and overlooking the Ring Road between Höfn and Vík. It is the largest active volcano in the country, and on the summit crater's northwestern rim is Hvannadalshnúkur, the highest peak in Iceland at . Geographically, Öræfajökull is considered part of Vatnajökull, and the area covered by glacier is within the boundary of Vatnajökull National Park.

Nýey
Nýey (), Nýeyjar , Nyø (Danish), was an island that formed in 1783 due to an underwater eruption in the Mid-Atlantic Ridge southwest of Reykjanes, Iceland. It disappeared within a year. History The formation of "Nýeyjar" began on May 1, 1783. It attracted a lot of attention and some connected it to the 1783 Calabrian earthquakes. The captain of a 'small ship' (" :is: húkkerta") that sailed in the area, wrote in his diary about a burning island due southwest of Geirfuglasker. He tried to observe it but had to stay over half a mile away, due to the poisonous sulphurous smoke. King Christian VII of Denmark named the island "Nýey", ordered an expedition to it, and dedicated it to the monarchy with a Danish flag. He also planned for an inscribed stone to be placed on the island. It had disappeared by the summer of 1784, when Magnús Stephensen (Lawyer and Supreme Court Judge), planned to dedicate it to the king whilst en route to Copenhagen. See also * Eldeyjarboði a ...

Ljósufjöll
Ljósufjöll () is a fissure vent system and central volcano on the Snæfellsnes Peninsula in Iceland. The system has a length of about 90 km. The volcanic system contains cinder cones and is the only system on the peninsula that has erupted in recorded history. The eruption took place in the 12th century (1148) and cost the lives of around 80 people. One of them was the then bishop of Skálholt, Magnús Einarsson. The name derives from the central volcano and translates into English as "Mountains of the Light". The system is the largest Quaternary rhyolitic outcrop in the Snæfellsnes volcanic zone and as such the central volcano is highly silicic which causes the light coloration.

Langjökull
Langjökull (, Icelandic for "long glacier") is the second largest ice cap in Iceland (953 km2), after Vatnajökull. It is situated in the west of the Icelandic interior or Highlands of Iceland and can be seen clearly from Haukadalur. Its volume is 195 km³ and the ice is up to thick. The highest point of the ice cap (at ''Baldjökull'' at the northern end of Langjökull) is about above sea level. In the past, the largest recorded surface area was in 1840. Situation and form The glacier is roughly parallel to the direction of the country's active volcanic zone: north-east to south-west. It is about long and wide, and has a slightly narrower point roughly between the lake Hvítárvatn on the Kjölur mountain road to the east and the Þrístapajökull glacier to the west, near another smaller glacier, Eiríksjökull, which is not quite connected to Langjökull. It is the nearest large glacier to Reykjavík. The area of the glacier includes some mountains, e.g. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lakagigar
Laki () or Lakagígar (, ''Craters of Laki'') is a volcanic fissure in the western part of Vatnajökull National Park, Iceland, not far from the volcanic fissure of Eldgjá and the small village of Kirkjubæjarklaustur. The fissure is properly referred to as Lakagígar, while Laki is a mountain that the fissure bisects. Lakagígar is part of a volcanic system centered on the volcano Grímsvötn and including the volcano Þórðarhyrna. It lies between the glaciers of Mýrdalsjökull and Vatnajökull, in an area of fissures that run in a southwest to northeast direction. The system erupted violently over an eight-month period between June 1783 and February 1784 from the Laki fissure and the adjoining volcano Grímsvötn, pouring out an estimated 42 billion tonnes or of basalt lava and clouds of poisonous hydrofluoric acid and sulfur dioxide compounds that contaminated the soil, leading to the death of over 50% of Iceland's livestock population, and the destruction of the va ...
