• Britain is the all-clear for Friday and the weekend
• 700 flights canceled estimated
• BA said the test flight of the red zone "found nothing"

I'm going to wind up the blog now looks good for the day with the travel outlook cleared of volcanic ash as the sky over Europe. 15:55: I'm going to stop the blog of the day, with more prospects to look good as volcanic ash approved comments skies of Europe. Thank you all for your.

A summary of the facts of the day:

• Met's Office, said the aviation industry that forecasts dense cloud of ash for the United Kingdom on Friday really are one of more because the volcano not erupting Grímsvötn. The UK is expected Consequently, in ash, low density, on Friday, which means that each airline can operate in the United Kingdom funds will be covered.

• The airports of Berlin, Hamburg and Bremen have reopened Kingdom, after that morning when the ash cloud reached closed the skies of United, but Germany led to disruptions in. European air traffic controllers expected that 700 flights today canceled be, but said the European airspace could be back to normal Thursday. The airlines have accused the German authorities to be too careful

• Willie Walsh, chief executive of British Airways and Iberia, echoing criticism of Ryanair in the UK for dealing with the challenges set by volcanic ash, and said that one of its aircraft by Ash said, stolen by BA "red zone" (ie, with the ashes in high density) for 45 minutes in Scotland and northern England and found nothing. "

• The British government is trying to hire a plane to Germany or to monitor the atmosphere of Ireland, because he ordered it – especially for ashes – will not be ready until July.

Things seem to be gradually returning to normal. 15.41 Clock: seems to gradually return to normal. Things Dutch airline KLM said it expected that all KLM flights back on schedule to:

Currently, the cloud of volcanic ash does not touch all our destinations KLM. Based on latest available information and expertise on all KLM flights will begin again on time.

But it should be noted that most airlines are still advising customers to check the status of their flights before departure.

Dr. Andy Hooper, a professor at the Technical University of Delft, says that we are in a phase of eruptions from Icelandic volcanoes laundering charges, partly because ice caps are shrinking, the pressure drop the hot mantle material Beneath That Feeds The Icelandic eruptions: 15.22 Clock: Dr. Andy Hooper, a professor at the Technical University of Delft, says that we are entering a phase of past outbreaks of the Icelandic volcanoes, in part because of the ice caps shrink reduces the pressure on the hot mantle material powers to Iceland Horse eruptions:

The number of volcanic eruptions under the ice cap Vatnajökull, the largest known (including Grímsvötn) seems to wax and wane on a cycle of about 140 years. There are up to three eruptions produced ash per decade considerable time and less active in times of low activity. In fact, between 1940 and 1980, there was no such eruptions of these volcanoes, and there are now four within 15 years.

But perhaps more important than the number of flares, the intensity of relapses, even in times of high activity, which means to increase, that the amount of ash and ash increases the chances of reaching Europe.

He said the threat is through a large crack eruption, which occurred only twice in the last 800 years, both in times of high volcanic activity, far worse than the effect on traffic:

The Laki fissure eruption in 1783 killed perhaps a quarter of Iceland's population and led to the deaths of thousands throughout Europe by poisoning and extreme cold. While we might expect to mitigate the immediate effects of poisoning in modern times, the climate effects would still have devastating effects on plants.

In addition, the ice caps since the late 19 Century decreased – estimated Vatnajokull sank in this time of mass at 400 billion tons. This leads to reduced pressure on the hot mantle material that the eruptions in Iceland feeds to produce a magma booster.

In fact, since the last ice age, volcanic activity was 30 times higher than today.

Perhaps our only salvation is in the short term at least, is that it take some additional time for this magma to find its way to the surface.

Good news. 14.46 Clock: News. Good It seems that the green light for Friday and the start of half term, if Grímsvötn on it keeps a lid.

According to data published recently, the aviation industry in the UK, the Met Office is confident that the forecasts are more accurate by a dense cloud of ash for the United Kingdom on Friday, because of the volcanic eruption has ceased. Accordingly, the United Kingdom probably ash, low density, on Friday, which means that each airline can operate in the United Kingdom funds will be covered. The Met Office forecast model is its approximately 18 hours later on a more definitive.

A source said airline industry an interesting point: the United States and the Middle East Airlines would be removed and have landed in Britain and Friday anyway, because they are made not with the Met Office forecasts and charts of the company WSI, obviously not show a high density of ash France. So, British Airways and Virgin Atlantic have as Emirates Airlines and American Airlines have been grounded flew into the sunset.

02.36 Clock: The British Geological Survey collects information about public statements made by volcanic ash in the UK Grímsvötn the eruption. It is that people record their observations in the next 24 hours.

A simple questionnaire was developed with questions like "Did you see ash and dust on your windshield?" and "Do you have the sulfur smell (rotten eggs)?"

A map showing the survey results in real time can be found on the website.

The BGS said the survey responses will allow it to confirm the results of the models of the ashes, on which the dismissals are based.

Ash samples were also collected from around the country and analyzed for more information about the types of ash that reached to provide the United Kingdom.

Despite dissent from some airlines, the Airport Operators Association has applauded the spirit of co-operation within the aviation industry that it claims to have witnessed in recent days. 02.19 Clock: Despite disagreement on some airlines, airport operators Association has applauded the spirit of cooperation within the aviation industry have said they experienced in the last days.

Darren Caplan, Director General of ESA, said that the guidelines have before the eruption would Grímsvötn UK airspace closed.

The degree of cooperation between scientists, weather experts, has unparalleled regulators of the CAA, NATS air traffic control, € Control and airlines and airports. And many in the industry worked very hard, day and night to provide the necessary funds, regulators and airlines to risk assessment, whether or not to fly can do.

Here is a summary of recent developments: 01.13 clock: Here is a summary of recent developments:

• The airports of Berlin, Hamburg and Bremen have reopened Kingdom, after that morning when the ash cloud reached the closed skies of United, but has led to disturbances in Germany. European air traffic controllers expected that 700 flights will be canceled today, but said that could be back to normal in European airspace Thursday. The airlines have accused the German authorities to be too careful

• Willie Walsh, chief executive of British Airways and Iberia, echoing criticism of Ryanair in the UK for dealing with the challenges set by volcanic ash, and said that one of its aircraft by Ash said, stolen by BA "red zone" (ie, with the ashes in high density) for 45 minutes in Scotland and northern England and found nothing. "

• The decline of the outbreak Grímsvötn raises the Met Office for "urgent" revision of the forecasts predict that Friday a cloud of ash high density to the United Kingdom at an altitude of 35,000 feet or more, said sources aviation.

• The airlines are pressing the Civil Aviation Authority regulatory changes in ash that prevent "flying under" the cloud. This would avoid landing to start at Heathrow airport, and even when the cloud of 35,000 feet above not in danger, and to achieve them. It is believed that the Civil Aviation Authority focused on politics today.

• The British government is trying to hire a plane to Germany or to monitor the atmosphere of Ireland, because he ordered it – especially for ashes – will not be ready until July.

13.10 Berlin Airports has now re-opened boarding flights.

01.06 Clock: Iceland horses vizier website has a picture of Grímsvötn shows that steam coming from the crater. He says:

The outbreak Grímsvötn seems to end. Witnesses reported ventured near the crater this morning that the activity is almost non-existent. Scientists are on their way to an aircraft to assess the situation, but as it is, it seems that the volcano spews ash into the atmosphere stopped.

Archives United spectacular photos of the volcano erupting in 1998, even .

A hamburger at the airport site is "resume flight operations Cdn at the airport Hamburg today, May 25st, 12:00 noon (11 clock GMT) 24:42. Said a message on the website of the airport Hamburg:" The operations can at Hamburg Airport today, 25pc May, 12.00 clock (11 clock Paris) resume. But he adds:

The worst is over and now the cleanup begins. Our geologists say that the rash decreased from day to day and the problems that should arise in our neighboring countries by volcanic ash released quickly.economic normal activities.

NAVAIR is responsible for air traffic services in Denmark, 11:56: NAVAIR, responsible for air traffic control in Denmark said a small area in Danish airspace closed to 04.00 London time clock But this is not the "normal traffic in Danish airspace"

Based on projections for the ash cloud, the Danish authorities closed the airspace below 6 km altitude in the south-western North Sea.

11:44: EasyJet says the Hamburg airport remain closed until 14 clock, London and Berlin Schoenefeld will remain closed until at least 13 hours in London .

He says it offers passengers of canceled flights, free transfers and refunds online.

The Guardian northern editor Martin Wainwright, the message from a pair of two plays volcano victims: 11:15: north-editor The Guardian, Martin Wainwright has news of a couple of times, two volcano victims:

Travelers at airports disrupted the north of England by the eruption had Grímsvötn compensation in the form of sunsets caused strikingly beautiful high through clouds of ash into the sky. The Tees Valley and rural Northumbria at Newcastle upon Tyne round at the airport in Ponteland were immersed in a golden glow with bright red streaks and dusk.

The show was even more spectacular in Iceland itself, but only proved little consolation for two in the northeast of the capital Reykjavik, where the victims of the volcano remained stuck for the second time.

Catherine Coulter, manager of the 26-year-old events in Gateshead, and her partner Christopher Duhaut were due back at work Monday, but remain in Iceland after the grounding of all flights from Keflavik Airport. Last year, their dream trip-of-Life was canceled due to the outbreak Eyjafjallajokull.

Coulter said it was "strange, the ash cloud Clock extends so close." The couple was admiring the snow fields in Iceland, if Grímsvötn broke, but now expect the first flight to Reykjavik from the United Kingdom from a permitted.

Dr. David Rothery of the Open University Volcano Dynamics Group, said, stopped his hand ash-producing eruption, the rate for the Time Being: 11:03: Dr David Rothery, The Open University Volcano Dynamics Group, said production from the ashes outbreak main set ended for the moment:

Most were the ashes of Grímsvötn in the last two days made blown north, and the ash was blown earlier passed in Scotland now.

Shortly after midnight tremor began Grímsvötn what was due to a rapid decline in the supply of magma and volcanic gas in the end, and at seven Paris eruption column could be seen on the radar. I am cautiously optimistic that the main phase has produced the ash eruption stopped now. However, he comes back – next week, next year, ten years or more to come probably.

There are also produce other volcanoes in Iceland ash clouds worse than we experienced this week. As a frequent traveler, I am pleased that the regulators and the airline industry better prepared than they seem in the past year, and almost all airlines are willing to err on the side of caution.

11:00 clock: The Guardian has a live online Q & A to 2.00 clock on the clouds of volcanic ash. You can post your questions now .

The experts answer all your questions about the possible effects of the ash cloud:

• John A. Stevenson, research fellow at the Faculty of Geosciences, University of Edinburgh, United Kingdom. His work explores the types of eruptions and weather conditions, which are deposited on ash from Icelandic volcanoes in Scotland and Northern Europe. In the last few days He has published regularly on the rash on his blog Grímsvötn .

• Colin Brown, Director of Engineering at the Institution of Mechanical Engineers. Active in his previous job, from aircraft engines at Rolls Royce. He has to follow the progress of the ash cloud.

The Guardian match in Germany, writes Helen Pidd, this is the country bans Could be Lifted this afternoon. 10:45 clock: Germany correspondent for the Guardian, Helen Pidd, writes that the bans lifted, the country could be this afternoon.

The ash cloud caused misery for passengers to and from Germany today in the north. Hamburg and Bremen airports in the early hours of clock time and 11 were closed (10 clock GMT), the airspace over Berlin was closed.

No takeoffs or landings are expected to attend one of two airports in the capital, at least up to 14 clock time, said the body of the ATC, the ATC (DFS). On a normal Wednesday, Berlin Schoenefeld and Tegel handle 700 flights per day.

The airport has been opened in Bremen and Hamburg, was to follow suit at noon local time.

The German government's accusation that has reacted with caution, "said Helen:

German Transport Minister Peter Ramsauer said he expects the bans be lifted on Wednesday afternoon, for there were no significant concentration of ash moving to Germany and the sky be clear, once the cloud that was over. The Minister said in a television interview there was a "sound legal basis" for the flight ban, the
has been criticized as too drastic by the airlines.

Other European countries have adopted the German policy-fly when the ash concentration of more than 2,000 micrograms per cubic meter. "Safety first," says Ramsauer the public channel ARD on Wednesday morning.

Does anyone have a spare monitor volcanic ash flat? 10.36: Does anyone have a replacement plan for monitoring volcanic ash in concrete terms? The government seeks to borrow or Ireland level for monitoring the atmosphere in Germany because he ordered it – for ashes – will not be ready until July.

Yesterday, International Air Transport Association has written Secretary, Philip Hammond laments the lack of control over the aircraft to transport. In the meantime, the British government is based on the likes of British Airways and Ryanair to monitor the clouds.

BA has dutifully reported its findings to the Civil Aviation Authority, while Ryanair to publish its findings by block bookings Michael O'Leary on Sky News.

Here is a round-up of some of the airlines whose services are part of the ash cloud (most of it has come about 10:35 are affected: Here is an overview of some of the airlines whose services are affected by the cloud of ash (much made was the the relevant British Foreign and Commonwealth Office website ):

Aviation Industry sources said the Met Office "urgent" Reconsidering 9:48: Sources in the aviation industry, said the Met Office is "urgently" to reconsider forecasts that predict a cloud of ash high density to the United Kingdom, Friday , At an altitude of 35,000 feet or more. Obviously, meteorologists believe the nation, much maligned in the past 24 hours, that drops the outbreak Grímsvötn result in less ash in the air at the end of the week. Consequently, the effect will be to the United Kingdom less radical. We should know more in 14 hours.

Meanwhile, the airlines under pressure from the civil aviation authority of the regulatory changes in ash that prevent are "flying under" the cloud. This would avoid at Heathrow airport takeoff and landing, even when the cloud reached 35,000 feet above them and not in danger. It is believed that the Civil Aviation Authority focused on politics today.

Willie Walsh, who was very critical of the flight ban as a result of the eruption Eyjafjallajökull from last year 9:40: Willie Walsh, who was highly critical of the ban on flights in the wake of the eruption last year Eyjafjallajökull is back :

The head of British Airways and Iberia is the noise on the treatment of the cloud of volcanic ash, this morning, after stating that the test flight BA "found nothing" after the flight through a plume of smoke as by regulators as too dangerous for normal commercial flights.

In response to the criticism of Ryanair, said Willie Walsh, the aircraft was flying through ash "red zone" for 45 minutes in Scotland and northern England, and met no problems. The Director General of the International Airlines Group, parent company of the airline said Britain and Spain, as the cloud from the volcano Grímsvötn away from the airspace of the United Kingdom and began to travel impact in Germany.

Walsh said today BBC4 program that the plane at different altitudes over an area of ​​the Met Office described contain high concentrations of ash – a level that no commercial carrier has received the security clearance function. "Flew the beginning, on the north of England, Newcastle, Glasgow, Edinburgh, back in Newcastle. The aircraft returned and examined. All filters have been removed and will be sent to a laboratory for analysis. The simple answer is that we found nothing. "

Ryanair battle with the regulator has dragged say Into This morning with the Irish Aviation Authority that it is "still" evaluating the airline's request by medium density fly ash. 09:26: Ryanair battle with regulators has brought in this morning, with the Irish Aviation Authority said he was "still" assessing the airline request to fly ash by the average density of the latter. Period forced Ryanair cancel flights Scotland yesterday, and you can imagine the language that Michael O'Leary calling the IAA used.

authorized under the provisions of ash, Ryanair in Dublin, were allowed to carry passengers through the spring without the permission of the IAA. Not surprisingly, O'Leary, boss of Ryanair, is angry.

The volcano has stopped erupting Grímsvötn, Under British weather officials. 9:23: The volcanic eruption Grímsvötn has stopped in to the meteorological services of the United Kingdom soon. More details.

Good morning. 9:10: morning. Good Welcome Grímsvötn live coverage of the Guardian of the disturbance caused by the volcano.

Here is a summary of recent developments:

• Theft at the airports in the UK United Kingdom largely returned to normal after high volcanic ash from the eruption allowed Icelandic sky.

• The problem has moved to Germany when the Berlin Tegel and Schönefeld two airports closed by 9 clock UK time (11 clock time). EasyJet said the Hamburg airport is closed until 14 clock time in London and would Ryanair said it had canceled all its flights to and from German airports of Bremen, Lübeck and Magdeburg up to 13 hours, UK time.

• British Airways said it carried out a test flight in the red zone (areas with high density of ash more than 4,000 micrograms per cubic meter) for about 45 minutes at different levels in Scotland and "found nothing".
