UK flights cancelled as a result of volcanic ash because of Icelandic Volcano

Volcanic Ash UK background and how to deal with it.

Iceland’s Eyjafjallajokull volcano started erupting on March 20 and has been gaining strength. Eruptions can send ash 11km into the stratosphere from the crator. Demands for an end for the no-fly ban comes from airlines

With atmospheric pressure high above the Atlantic between Iceland as well as the British Isles, winds blow the ash east and south towards Scandinavia and due north to western Europe.

The ash plume leading to trouble at the moment is likely to spread out.

The uncertainty then is regardless of whether further potent eruptions will result in similar difficulties inside weeks or months forward. When Eyjafjallajokull last erupted in 1821 it remained active for a year – and volcanologists fear that its activity might be a precursor to an eruption of nearby Mount Katla, which may be a great deal far more strong and disruptive, both locally in Iceland and in its global effect.

Volcanic Ash can be a very fine dust, thousands of metres up in the atmosphere, but the tiny particles are extremely sharp and abrasive when sucked into aircraft engines. Hence it causes flight suspension.

Chemically the ash is created predominantly of silica, the principal element of sand and glass. Inside a jet engine it can bring about serious damage to fan blades and clog surfaces; it might even melt and clog nozzles with molten glass.

But, looking at the bright side, you may see indirect signs with the ash if the sky is clear this evening, from the form of a outstanding sunset.

Eventually the volcanic ash is bound to come to earth, but the ash may be so widely dispersed by then as to be undetectable among local sources of dust and dirt. A great deal thicker volcanic ash is deposited close to erupting volcanoes.

Big volcanic eruptions send much more than adequate dust and gas to the atmosphere to have a meteorological effect. The most recent was the 1991 eruption of Mount Pinatubo inside Philippines, which cooled the planet by about 0.5°C over the following two years.

This Icelandic eruption isn’t effective adequate to possess such an effect, although it may do so within the time to come if the eruptions gain strength.

From the worst case, the eruption at Laki in Iceland in 1783 could possibly be an awful precedent. That emitted an estimated 120m tonnes of sulphur dioxide and a vast quantity of extremely fine dust, which caused a persistent haze across western Europe for several months – and is estimated to have killed tens of thousands of men and women via respiratory and other unwellness.

If anything like Laki happened now leading to additional Volcanic Ash UK affecting, then north Atlantic airspace may possibly have to be shut for months.
