when did the last volcano erupt in iceland
2010
title: Iceland text: 2010, a volcano in Eyjafjallajökull in the south of Iceland erupted for the first time since 1821, forcing 600 people to flee their homes. Additional eruptions on 14 April forced hundreds of people to abandon their homes. The resultant cloud of volcanic ash brought major disruption to air travel across Europe. Another large eruption occurred on 21 May 2011. This time it was the Grímsvötn volcano, located under the thick ice of Europe's largest glacier, Vatnajökull. Grímsvötn is one of Iceland's most active volcanoes, and this eruption was much more powerful than the 2010 Eyjafjallajökull activity, with ash and lava title: Volcanology of Iceland text: Volcanology of Iceland The volcanoes of Iceland include a high concentration of active ones due to Iceland's location on the mid-Atlantic Ridge, a divergent tectonic plate boundary, and its location over a hot spot. The island has 30 active volcanic systems, of which 13 have erupted since the settlement of Iceland in AD 874. Of these 30 active volcanic systems, the most active/volatile is Grímsvötn. Over the past 500 years, Iceland's volcanoes have erupted a third of the total global lava output. The most fatal volcanic eruption of Iceland's history was the so-called Skaftáreldar (fires of Skaftá) in 1783-84. The title: Volcanology of Iceland text: of the travel chaos seen across northern Europe. Though a relatively small eruption, the 2010 eruption of Eyjafjallajökull was notable for causing enormous disruption to air travel across western and northern Europe over a period of six days in April 2010. About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travellers. Bárðarbunga is a stratovolcano and is roughly 2,000 meters (roughly 6,560 feet) above sea level in central Iceland (64.63°N / -17.53°W). This makes it the second highest mountain in Iceland. The eruption series, Iceland's largest eruptions in 230 years that started on title: Iceland text: Park, Snæfellsjökull National Park, and Þingvellir National Park. The country is considered a "strong performer" in environmental protection, having been ranked 13th in Yale University's Environmental Performance Index of 2012. A geologically young land, Iceland is located on both the Iceland hotspot and the Mid-Atlantic Ridge, which runs right through it. This location 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 title: 2011 eruption of Grímsvötn text: 2011 eruption of Grímsvötn The 2011 eruption of Grímsvötn was an eruption in Grímsvötn, Iceland's most active volcano, which caused disruption to air travel in Northwestern Europe from 22–25 May 2011. The last eruption of Grímsvötn was in 2004, with the previous most powerful eruptions in 1783, 1873 and 1902. The Grímsvötn eruption was the largest eruption in Iceland for 50 years. The eruption is estimated to have started under the glacier at around 17:30 UTC on 21 May 2011 when an intense spike in tremor activity was detected. At around 19:00 UTC, the eruption broke the ice cover of
