Iceland has hundreds of volcanoes with approximately thirty volcanic systems active. Party to: Signed, but not ratified: Geography of Iceland Iceland ( )is an island country at the confluence of the North Atlantic and Arctic Oceans, east of Greenland and immediately south of the Arctic Circle, atop the constructive boundary of the northern Mid-Atlantic Ridge about from Scotland and from New York City. One of the world's most sparsely populated countries, Iceland's boundaries are almost the same as the main island title: Eurasian Plate text: Amurian Plate. The southerly side is a boundary with the African Plate to the west, the Arabian Plate in the middle and the Indo-Australian Plate to the east. The westerly side is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland. All of the volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 1783 eruption of Laki, and the 2010 eruption of Eyjafjallajökull, are caused by the North American and the Eurasian plates moving apart, which is a result of divergent plate boundary forces. The title: Geology of Iceland text: 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 title: Geology of Iceland text: Ridge by the Tjörnes Fracture Zone, another major center of seismicity and deformation. Glaciers cover approximately 11% of Iceland, the largest of which being Vatnajökull. As many glaciers overlie active volcanoes, subglacial eruptions can pose hazards due to sudden floods produced by glacial meltwater, known as jökulhlaups. Icelandic glaciers have generally been retreating over the past 100 years, with Vatnajökull having lost as much as 10% of its volume. 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 title: Iceland text: glaciers cover 14.3% of its surface; only 23% is vegetated. The largest lakes are Þórisvatn reservoir: and Þingvallavatn: ; other important lakes include Lagarfljót and Mývatn. Jökulsárlón is the deepest lake, at . Geologically, Iceland is part of the Mid-Atlantic Ridge, a ridge along which the oceanic crust spreads and forms new oceanic crust. This part of the mid-ocean ridge is located above a mantle plume, causing Iceland to be subaerial (above the surface of the sea). The ridge marks the boundary between the Eurasian and North American Plates, and Iceland was created by rifting and accretion through volcanism along
