Title: ICEARRAY
Content:  Iceland is located on the Mid-Atlantic Ridge, the extensional tectonic plate boundary between the North American Plate and the Eurasian Plate. It is also located over a deep-seated mantle plume known as the Iceland hotspot, which causes dynamic uplift of the Iceland Plateau, with associated volcanism and seismicity. The line of the Mid-Atlantic Ridge is offset by two transform zones in Iceland, the South Iceland Seismic Zone (SISZ) in the south and the Tjornes Fracture Zone in the north. The town of Hveragerdi is located at the western end of the SISZ, an area of considerable seismicity.
Title: Iceland
Content:  A geologically young land, Iceland is the surface expression of the Iceland Plateau, a large igneous province forming as a result of volcanism from the Iceland hotspot and along the Mid-Atlantic Ridge, the latter of which runs right through it. This means that the island is highly geologically active with many volcanoes including Hekla, Eldgjá, Herðubreið, and Eldfell. The volcanic eruption of Laki in 1783–1784 caused a famine that killed nearly a quarter of the island's population. In addition, the eruption caused dust clouds and haze to appear over most of Europe and parts of Asia and Africa for several months afterward, and affected climates in other areas. Iceland has many geysers, including Geysir, from which the English word is 
Title: Iceland Plateau
Content:  The Iceland Plateau is bounded on the south by the Reykjanes Ridge, on the west by the Greenland-Iceland Ridge, on the north by the Kolbeinsey Ridge, and on the east by the Iceland-Faeroe Ridge. It consists of a large igneous province that has been volcanically active since at least the Miocene epoch. The plateau has an average elevation of 1,700 meters above sea level. The geology of the Icelandic Plateau consists of three layers, closely mimicking the structure of oceanic crust but with one key difference, the second layer of the oceanic crust does not contain piles of lava flow like the Icelandic Plateau does. The first layer is composed of mainly sedimentary rock, the second layer is piles of lava flows, and the third layer is a thick layer of gabbro.
Title: Krafla
Content:   Iceland is a place where it is possible to see plate tectonics at work. It sits astride the Mid-Atlantic Ridge; the western part of the island nation is part of the roughly westward-moving North American plate, while the eastern part of the island is part of the roughly eastward-moving Eurasian Plate. The north–south axis of the Mid-Atlantic Ridge splits Iceland in two, roughly north to south. Along this ridge many of Iceland's most active volcanoes are located; Krafla is one of these. Krafla includes the crater Víti, one of two well-known craters by this name in Iceland (the other is in Askja). The 
Title: Iceland hotspot
Content:  The Iceland hotspot is a 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 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, in 934 (the world's largest basaltic eruption ever witnessed), Laki in 1783 (the world's second largest), and several eruptions beneath ice caps,

Content:  have generated devastating glacial bursts, most recently in 2010 after the eruption of Eyjafjallajökull. Iceland's location astride the Mid-Atlantic Ridge, where the Eurasian and North American Plates are moving apart, is partly responsible for this intense volcanic activity, but an additional cause is necessary to explain why Iceland is a substantial island while the rest of the ridge mostly consists of seamounts, with peaks below sea level. As well as being a region of higher temperature than the surrounding mantle, it is believed to have a higher concentration of water. The presence of water in magma reduces the melting temperature, which may also play a role in enhancing Icelandic volcanism.
Title: 2008 Iceland earthquake
Content:  Iceland straddles the mid-Atlantic ridge where the Eurasian and North-American tectonic plates move away from each other. Volcanic activity is common along such divergent boundaries but strong earthquakes are rare. In Iceland the ridge is somewhat off-set, creating two transform faults where plates move horizontally along each other. One is in the north of the country and one in the south; the strongest Icelandic earthquakes happen along those transform faults. The 29 May quake is classified by geologists as typical Suðurlandsskjálftar (literally: Southern Iceland quakes), which happen on the southern fault.
Title: Geology of Iceland
Content:  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.
Title: Geological deformation of Iceland
Content:  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 
Title: Plate theory (volcanism)
Content:  The vast majority of volcanic provinces which are thought to be anomalous in the context of rigid plate tectonics have now been explained using the plate theory. The type examples of this kind of volcanic activity are Iceland, Yellowstone, and Hawaii. Iceland is the type example of a volcanic anomaly situated on a plate boundary. Yellowstone, together with the Eastern Snake River Plain to its west, is the type example of an intra-continental volcanic anomaly. Hawaii, along with the related Hawaiian-Emperor seamount chain, is the type example of an intra-oceanic volcanic anomaly.
