Eldeyjarboði
Eldeyjarboði () is a blind skerry located about 57 km southwest of Reykjanes, Iceland. It is part of the Mid-Atlantic Ridge. A submarine eruption occurred in 1830. In January 2020 the Icelandic Met Office stated that two earthquakes occurred 26 km southwest and 32 km south-southwest of Eldeyjarboði.

Islands Of Iceland
This is a list of islands of Iceland. It includes all islands larger than 1 km2, as well as a number of smaller islands that are considered significant either because they are or used to be inhabited, or for specific historical, geographical or geological reasons. Thousands of other small islands and skerries are found along the coast, especially in Breiðafjörður. The areas of some of these islands may vary comparatively rapidly due to volcanic activity and subsequent action by the sea. In the case of the groups of islands in Breiðafjörður, no area is listed. This is because measurement of the smaller islands is made difficult by a very large tidal range of up to six metres.

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 ...

Skerry
A skerry is a small rocky island, or islet, usually too small for human habitation. It may simply be a rocky reef. A skerry can also be called a low sea stack. A skerry may have vegetative life such as moss and small, hardy grasses. They are often used as resting places by animals such as seals and birds. Etymology The term ''skerry'' is derived from the Old Norse ', which means a rock in the sea (which in turn derives from the Proto-Indo-European root *''sker''-, "cut", in the sense of a rock cut off from the land). The Old Norse term ' was brought into the English language via the Scots language word spelled or . It is a cognate of the Scandinavian languages' words for ''skerry'' – Icelandic, fo, sker, da, skær, sv, skär, no, skjær / skjer, found also in german: Schäre, fi, kari, et, skäär, lv, šēra, lt, Šcheras and russian: шхеры ().

Reykjanes
Reykjanes () is a small headland on the southwestern tip of the Reykjanes Peninsula in Iceland, giving the main peninsula its name. The region is about from Iceland's international airport. As the name means "smoking peninsula" connected to volcanic activity, there are also other peninsulas by this name in Iceland, e.g. the peninsula of Reykjanes in Ísafjarðardjúp Ísafjarðardjúp () is a large fjord in the Westfjords region of Iceland. Its name translates to ''Depth of the fjord of sea ice''. Ísafjörður, capital of the Westfjords region, is situated close to the mouth of Ísafjarðardjúp in Skutul ....

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 ...

Mid-Atlantic Ridge
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about per year. Discovery A ridge under the northern Atlantic Ocean was first inferred by Matthew Fontaine Maury in 1853, based on soundings by the USS ''Dolphin''. The existence of the ridge and its ...

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 ...

Geology Of Iceland
The geology of Iceland is unique and of particular interest to geologists. Iceland lies on the divergent boundary between the Eurasian plate and the North American plate. It also lies above a hotspot, the Iceland plume. The plume is believed to have caused the formation of Iceland itself, the island first appearing over the ocean surface about 16 to 18 million years ago. The result is an island characterized by repeated volcanism and geothermal phenomena such as geysers. The eruption of Laki in 1783 caused much devastation and loss of life, leading to a famine that killed about 25% of the island's population and resulted in a drop in global temperatures, as sulfur dioxide was spewed into the Northern Hemisphere. This caused crop failures in Europe and may have caused droughts in India. The eruption has been estimated to have killed over six million people globally. Between 1963 and 1967, the new island of Surtsey was created off the southwest coast by a volcanic eruption. Geol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Geological Deformation Of Iceland
The geological deformation of Iceland is the way that the rocks of the island of Iceland are changing due to tectonic forces. The geological deformation explains the location of earthquakes, volcanoes, fissures, and the shape of the island. Iceland is the largest landmass (102,775 km²) situated on an oceanic ridge. It is an elevated plateau of the sea floor, situated at the crossing of the Mid-Atlantic Ridge and the Greenland-Iceland-Faeroe Ridge. It lies along the oceanic divergent plate boundary of North American Plate and Eurasian Plate. The western part of Iceland sits on the North American Plate and the eastern part sits on the Eurasian Plate. The Reykjanes Ridge of the Mid-Atlantic ridge system in this region crosses the island from southwest and connects to the Kolbeinsey Ridge in the northeast. Iceland is geologically young: all rocks there were formed within the last 25 million years. It started forming in the Early Miocene sub-epoch, but the oldest rocks found at t ...

Former Islands
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...
