Air travel could be curtailed repeatedly
The previous eruption of the Eyjafjallajökull volcano, whose ash cloud has shut down airspace over Britain, lasted for more than a year, according to an expert. The Eyjafjallajökull volcano erupted for the first time in 200 years on March 20, in a dramatic display that sent fountains of lava spewing into the air.
All flights to British airspace have been suspended after ash caused by the eruption forced air traffic controllers to restrict take-offs and landings.
Professor Bill McGuire, of the Aon Benfield Hazard Research Centre at University College London, said the previous eruption, in December 1821, lasted until January 1823.
He said air travel could be curtailed repeatedly if the current eruption lasted the same amount of time.
However, he added: "There is no way of knowing for certain how long this eruption will last based on previous events. The level of disruption would also depend on how much gas and ash is produced."
