quote:Big Brother Katla showing signs of possible eruption
LONDON - A second, much larger volcano in Iceland is showing signs that it may be about to erupt, scientists have warned.
Since the start of the Eyjafjallajökull eruption, which caused cancellations of thousands of flights in Europe because of a giant ash cloud, there has been much speculation about neighboring Katla.
An initial research paper by the University College of London Institute for Risk and Disaster Reduction said: "Analysis of the seismic energy released around Katla over the last decade or so is interpreted as providing evidence of a rising ... intrusive magma body on the western flank of the volcano."
Earlier seismic energy release at Katla is associated with the inflation of the volcano, which indicates it is close to failure, although this does not appear to be linked to seismicity around Eyjafjallajökull," it added.
"We conclude that given the high frequency of Katla activity, an eruption in the short term is a strong possibility," the report said. "It is likely to be preceded by new earthquake activity. Presently there is no unusual seismicity under Katla.
Icelandic President Ķlafur Grímsson has warned governments around Europe that a significant eruption at the volcano is close. "We [Iceland] have prepared ... it is high time for European governments and airline authorities all over Europe and the world to start planning for the eventual Katla eruption," he said.
The UCL scientists, engineers and statisticians also criticized the response to the earlier eruption.
"The impact of the eruption on regional airspace could have been predicted and better prepared for as the growing problem of aircraft-ash cloud encounters has been recognized for decades," the report added.
"Similarly, the potential for ash clouds, specifically from Icelandic volcanoes, to interfere with air traffic in UK, European and North Atlantic air-space was appreciated by the aviation industry well before the start of the Eyjafjallajökull eruption," it said.
"The response to the ash cloud’s arrival in UK and adjacent airspace was entirely reactive and therefore less effective than it should have been."

misschien is het wel een voorbode
hmjah, sahara-zand is een baksteen in vergelijking met vulkaan-as, dus denk dat er wel wat verschil in impact op een motor aan zit.quote:Op vrijdag 28 mei 2010 09:37 schreef Re het volgende:

Zeer interessante docu
Op het laatst zeiden ze ook dat het geen kwestie is van 'Of' maar van 'Wanneer' die andere, veel gevaarlijker vulkaan in de buurt wakker zal schudden. Een wereldwijde catastrofe....
Hmm, dat kan je nog wel eens tegenvallen:quote:Op maandag 31 mei 2010 15:16 schreef Ermanon het volgende:

http://www.huffingtonpost(...)-a-2nd_b_541755.htmlquote:Katla volcano, located near the southern end of Iceland's eastern volcanic zone, is hidden beneath the Myrdalsjökull icecap.
The subglacial dominantly basaltic volcano is one of Iceland's most active and is a frequent producer of damaging jökulhlaups, or glacier-outburst floods. A large 9 x 14 km subglacial caldera with a long axis in a NW-SE direction is up to 750 m deep. Its high point reaches 1380 m, and three major outlet glaciers have breached its rim.
Although most historical eruptions have taken place from fissures inside the caldera, the Eldgjá fissure system, which extends about 60 km to the NE from the current ice margin towards Grímsvötn volcano, has been the source of major Holocene eruptions. An eruption from the Eldgjá fissure system about 934 AD produced a voluminous lava flow of about 18 cu km, one of the world's largest known Holocene lava flows. Katla has been the source of frequent subglacial basaltic explosive eruptions that have been among the largest tephra-producers in Iceland during historical time and has produced dacitic explosive eruptions during the Holocene.

Experts are concerned that the present volcanic eruption could trigger activity at Mount Katla, which is potentially much more dangerous. Its last major eruption was in 1918. Icelandic volcanologists consider it plausible that Katla may erupt, and that is why they are monitoring Katla very closely right now. There are eruption channels between Eyjafjallajökull and Katla and magma could shoot into the Katla volcano. Katla might only need a nudge. Effects of Katla's eruption would put the present air travel chaos in the shade, inflicting much greater economic losses upon Europe. Deposits from the ash cloud formed by Katla when it erupted spectacularly in 1755 can still be found in peat bogs in Shetland and other parts of northern Europe.
