Volcanic Ash Cloud from Iceland Likely To Disturb Flights to Nigeria from UK
As the latest forecasts from the Met Office a thick cloud is likely to cover much of Scotland by tomorrow morning can disturb the schedule of flights worldwide.
Volcanic ash consists of small tephra, which are bits of pulverized rock and glass created by volcanic eruptions less than 2 millimeters’
Despite this airline stocks fell early on Monday, with losses in heavyweights such as Lufthansa, Air France and Scandinavian SAS leading the European travel and leisure index down 1.8%.
There are three danger effects are predicted that can affect worldwide flights
1. Gas release under decompression causing magmatic eruptions.
2. Thermal contraction from chilling on contact with water causing phreatomagmatic eruptions
3. Ejection of entrained particles during steam eruptions causing phreatic eruptions.
Last year, ash from an explosion at Iceland's Eyjafjallajokull volcano forced the closure of European airspace for six days. Some 10 million passengers were left stranded for days at airport lounges around the world following the eruption in April 2010. Experts and officials have said it is unlikely the Grimsvotn ash cloud would bring the same extent of misery.
Some experts say there is chance that Katla volcano, to the east of the Eyjafjallajokull glacier, may erupt. However, there is no sign of that at present. The Civil Aviation Authority uses this information to advise the air industry of any resulting no-fly zones. It also advises on "red zones" - were ash is present but flights can continue with tougher safety rules
