It is likely to be preceded by new earthquake activity. Recorded Major Eruptions. Katla’s 1918 VEI 4 eruption [visitklaustur.is]. First of all due to the high latitude of the volcano,a 'global impact' is unlikely, the majority of eruptions which transport ash globally and affect global temperatures are closer to the equator and if you look at past eruptions of Katla, the largest they reach is VEI 4/5 which is large, but not on the scale which Tambora or Pinatubo were. Katla volcano in Iceland is that nation’s largest and most destructive volcano. Source(s): The wikipedia entry on Katla gives adequate information to compare it to volcanoes with known VEI-5 and VEI-6 eruptions, especially taking into account the paper "The crustal magma chamber of the Katla volcano in south Iceland revealed by 2-D seismic undershooting" by O. Gudmundsson, B. Brandsdottir, W. Menke and G. E. Sigvaldason, which is available on the web. The major potential hazards are the jökulhlaup floods that can hit three different floodplains, an associated tsunami that can harass the south coast of Iceland and a volcanic ash cloud that endangers civil aviation on an unknown scale. It has historically erupted once every 40 to 80 years, making it statistically long overdue for a new eruption. Viimeisin suuri purkaus oli 1918 (VEI5), vuosina 1955 ja 1999 tapahtuneet purkaukset eivät rikkoneet jääkuorta. In practice this means that Katla is capable of producing 10 times more tephra than Eyjafjallajökull did. the larger neighbouring katla volcano. the Volcanic Explosivity Index (VEI) 1. On a scale of 0-8, previous eruptions have had a VEI (Volcanic Explosivity Index) of approximately between 4 and 6. Volcano eruptions are rated on a scale of 0 - 8 known as the Volcanic Explosivity Index (VEI) based on ash cloud height, the total volume of lava and other products. Grímsvötn Encyclopedia Article. Katla erupts every 40-80 years. It is located on the south coast of the island of Iceland, about 3km inland.

The Katla volcano has an average eruption range of 40 - 80 years. Katla Volcano This is one of several significant post-caldera vents within Semisopochnoi. The eruption created a series of lakes known as Veiðivötn, many of these lakes are actually former explosion craters. Volcanic ash from a Katla eruption The explosive stage of the eruption began under the Eyjafjalla glacier in the early hours The last time it erupted, back in 1918, Katla belched out ash and gasses for over five weeks. Vuodesta 930 alkaen on muistiinmerkitty 16 Katlan purkausta. Katla is known to be seismically active, although seasonal fluctuations have been attributed to her ice cap melting during the summer and the resulting reduction of pressure on the magma chamber. A VEI 7 will have global repercussions, like the 2004 boxing day tsunami and the fukushima tsunami but much worse , loss of life during and post event could be millions, climate change, ... “At 7:55AM an M2.8 earthquake was detected in southern caldera of Katla volcano. Though the increase in seismic activity is not a direct indicator of an impending eruption, the last major eruption was 95 years ago so the volcano is being carefully watched. Iceland, Eyjafjallajökull, Mars, Laki, Bacteria Read More. Katla hasn’t erupted forcefully since 1918, although there may have been small eruptions under the icecap that didn’t break the ice, including ones in 1955, 1999, and 2011. Katla in Iceland is one of the famous volcanoes of the world for the ferocity of the eruptions and associated j?kulhlaups. Volcano, vent in the crust of Earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases.A volcanic eruption is an awesome display of Earth’s power. Katla in Iceland is one of the famous volcanoes of the world for the ferocity of the eruptions and associated jökulhlaups. Geological evidence shows that this has happened. That eruption was classified as a VEI (Volcanic Explosivity Index)-4 or VEI-5 event, which propelled roughly 0.7 cubic km of debris from beneath the earth’s crust into the atmosphere. Katla este unul dintre cei mai mari vulcani din Islanda Date generale. Its unusual and difficult to pronounce name comes from the combination of various words with different meanings. In 1447, Bárðabunga erupted in an eruption considered to be a VEI-6, the highest number any volcano in Iceland had reached on the VEI-scale, save Katla, which also reached this metric. Eyjafjallajokull volcano, Icelandic volcano whose name is derived from an Icelandic phrase meaning ‘the island’s mountain glacier.’ Lying beneath Eyjafjallajökull (Eyjafjalla Glacier), its summit rises to 5,466 feet (1,666 meters) above sea level. First of all due to the high latitude of the volcano,a 'global impact' is unlikely, the majority of eruptions which transport ash globally and affect global temperatures are closer to the equator and if you look at past eruptions of Katla, the largest they reach is VEI 4/5 which is large, but not on the scale which Tambora or Pinatubo were. It is very active; twenty eruptions have been documented between 930 and 1918, at intervals of 20–90 years. Katla eruptions are estimated to be VEI 5 (Volcanic Ex-plosivity Index) [10]; this is far greater than Eyjafjal-lajökull who barely made VEI 4. The major potential hazards are the j?kulhlaup floods that can hit three different floodplains, an associated tsunami that can harass the south coast of Iceland and a volcanic ash cloud that endangers civil aviation on an unknown scale. Figure 1: Map showing the location of the two stages of the Eyjafjallajökull event, Katla volcano and the Red Cross support centre locations.

Iceland’s Katla volcano frequently produces explosive eruptions (VEI 3-5) that generate large quantities of ash and powerful glacial floods (jökulhlaups). Iceland is the most volcanic place in the world. Katla is a large volcano in southern Iceland. The eastern flank of Mount Cerberus Cone, Semisopochnoi Caldera, is pictured, September 17, 2005, Alaska, U.S. Prior eruptions have measured with a Volcanic Explosively Index of between VEI-4 and VEI-6 on a scale of 0 to 8. Eyjafjallajokull is a volcano that is entirely covered by an ice cap. All of Katla's eruptions have been between 4 - 6 VE. In previous eruptions Katla has produced many eruptions with a Volcanic Explosive Index (VEI) of 5, although it has produced a VEI-6 eruption, similar to that of the Pinatubo eruption in 1991. The 1918 eruption of Katla produced five times as much ash as Eyjafjallajökull did in 2010. In 2000, Hekla was undergoing a VEI 3 eruption, small in comparison to its bigger eruptions, producing an ash plume that rose up to 15 km and travelling north across Iceland. During this eruption, a NASA airplane accidentally flew through the plume, resulting in the first ever directly recorded measurements of a volcanic plume! Though people may think it is dangerous to visit a volcano as a tourist attraction, the Katla Volcano is a dormant volcano; it looks more like an iced mountain than a volcano.
