Last year was called Eyjafjalla. This year has a simpler name: Grímsvötn. But they have something in common: they are both Icelandic volcanoes and both have the ability to sow chaos in European airspace. This happened last year, when the volcanic ash cloud reached the continent and forced to ground most of the fleet.
This year, Europe seems more prepared: have distinguished three levels of risk and most airlines are prepared to fly with volcanic clouds low or medium risk. The Civil Aviation Authority (CAA) in the UK said yesterday that the measures taken since last year "will help to limit any disruption in the event that volcanic ash reached this week in European airspace." But the CAA has warned that "can not rule out a disorder of aviation." That will depend on the evolution of the volcanic eruption and the cloud, depending on winds and weather.
The cloud is expected to reach Scotland yesterday morning. In the next few days are believed to come to Ireland and England. Air traffic has been affected. KLM held yesterday the first cancellations, the airline suspended 16 flights scheduled for this morning from or arriving in Aberdeen, Glasgow, Edinburgh and Newcastle.
British Airways will not operate any flights between London and Scotland to three in the afternoon (GMT Spanish). Loganair and Eastern Airways also canceled flights to the islands. This time the volcanic cloud is denser, which apparently makes the ash fall before the ground and moving away from Iceland is lighter.
In addition, the winds blowing in Iceland this year with less force than in 2010. Another positive aspect is that the two previous eruptions Grímsvötn in 1998 and in 2004, lasted just one week. In contrast, Eyjafjalla had not erupted since 1921, when he did in April 2010 had no parameters to estimate its duration.
Barca, pending the sky The Icelandic volcano has this year another common denominator with the last year: it coincides with a key match of FC Barcelona in the Champions League, the great European football tournament. This time it's final in London on Saturday against Manchester United. In 2010, the Barcelona and was forced at the last minute to travel by coach to Milan to play the semi-final first leg against Inter.
The accumulated fatigue in this journey has been considered one of the two keys of defeat in that game. The other key was the arbitration of a countryman of the then Inter coach Jose Mourinho. This time, Barcelona has more time to prepare for the trip. But the volcanic cloud can have a major impact on the nearly 25,000 fans with tickets for Wembley Barça.
Many of them expect to travel by plane. But it also may be affected who are traveling by train or by bus or car for a possible closure of airspace saturate both the train and the ferries crossing the English Channel. But according to European aviation authorities, the big difference from last year is that the industry is better prepared.
In 2010, traffic came to halt in 20 countries as Europe had never experienced a volcanic cloud as caused by the record Eyjafjalla and plane crashes near volcanoes Asian panic shot years ago and governments opted for drastic way: declare the closure of airspace immediately. This year we have identified three levels of risk to aviation.
The lower level is where the density of the volcanic cloud is less than two grams of ash per ten cubic meters of air. In this case it is considered that air navigation is not dangerous. If the volcanic cloud reaches a density of between two and four grams is considered that the risk is moderate and can fly only those companies which have submitted a safety report to ensure that their aircraft are ready to fly a swarm of these characteristics.
"Many airlines have already submitted such reports," according to CAA. For over four grams of ash per ten cubic meters of air is considered high risk and "no company has submitted safety reports to fly with the high density of ash."
