Alert Katla volcano in Iceland!

More than 500 tremors at the Katla volcano in the south of Iceland have been fixed over the past month. According to the scientist from the University of Iceland, Katla usually shows significant activity every 40 to 80 years. The last major eruption at the volcano was in 1918. In case of Katla’s eruption Europe risks to stay without air traffic for several months, while the meltdown of the glassier will lead to powerful flood. Andy Hooper of Delft University in the Netherlands, told Sky News Online the volcano, named Katla, has been causing concern since scientists recorded increased temperatures and seismic activity back in July. The Icelandic Met Office reports since July, "several hundred micro-earthquakes" have taken place in the area. Katla also showed signs of activity in 1999 and between 2002 and 2004, but did not erupt. On Oct. 5, there was an "intense swarm of earthquakes" at the volcano, the meteorological office reported. "There are presently no measurable signs that an eruption of Katla is imminent; however, given the heightened levels of seismicity, the situation might change abruptly," the Met office said in October. The volcano erupting is something business and holiday travellers don't even want to consider, given disruptions caused by other Icelandic volcanoes recently, including Grimsvotn in May and Eyjafjallajokull in April 2010. Both eruptions caused massive ash clouds, which brought transatlantic flights to a halt and left travellers stranded for days. Katla is one of Iceland's most frequently erupting volcanoes, the meteorological office said. The last eruption was in 1918, and lasted about a month.
