Iceland is located on the Mid-Atlantic Ridge.The North-American and Eurasianplates move apart- called constructiveplates. This causes magma to rise to the surface and form volcanoes.The latest eruption occurred under a glacier. The water cooled the lava quicklyresulting in glass particles entering the plume.http://en.wikipedia.org/wiki/File:Fimmvorduhals_second_fissure_2010_04_02.JPG 6. http://en.wikipedia.org/wiki/File:Ash_plume_from_Eyjafjallajokull_Volcano_over_the_North_Atlantic,_April_15,_2010_-_A2010105.1330.250m.jpg 7. Primary Impacts- occur as a direct result of the event.Secondary Impacts- occur because of a change to the environment as a result of the event. 8. 1Image c/o http://www.flickr.com/photos/prob1t/343692326/ 9. Image c/o http://en.wikipedia.org/wiki/File:Pyroclastic_flows_at_Mayon_Volcano.jpg 2 A A common and devastating result of some explosive volcanic eruptions. The flows are fast-moving currents of hot gas and rock, which travel awayfrom the volcano at speeds generally as great as 700 km/hr (450 mi/h). Thegas can reach temperatures of about 1,000 C. 10. Image c/o http://en.wikipedia.org/wiki/File:Lava-bomb-01.jpg 3 A mass of molten rock larger than 6.5 cm in diameter, formed when a volcano eruptsduring a lava eruption. They cool into solid fragments before they reach the ground. Lava bombs can be thrown many kilometres from an erupting vent, and often acquire aerodynamic shapes during their flight. 11. Image c/o http://en.wikipedia.org/wiki/File:Galunggung_lahar.jpg 4 A lahar is a type of mass movement composed of ash and water that flows downfrom a volcano, typically along a river valley. It may occur after rainfall or if volcanowith a lake or glacier erupts. 12. Image c/o http://en.wikipedia.org/wiki/File:MtCleveland_ISS013-E-24184.jpg 5Volcanic ash consists of small bits of pulverized rock and glass created by volcanic eruptions, less than 2 mm in diameter. Cause massive disruption as can damageairplane engines, therefore causing global transport disruption. Ash can build up on house roofs causing them to collapse. 13.

It often consists of a mix of carbon dioxide and sulphur dioxide amongst others. A significant eruption into the atmosphere can cause a volcanic winter. 14.
