Citat :
Iceland's most active volcano, Grimsvotn, has started erupting, scientists say.

The volcano, which lies under the Vatnajokull glacier in south-east Iceland, last erupted in 2004.

In 2010, plumes of ash from Iceland's Eyjafjallajokull volcano caused weeks of air travel chaos across Europe.

Officials say the latest eruption is unlikely to cause similar problems, although a flight ban has been imposed around the area.

Volcanic eruptions are common in Iceland, which lies along the Mid-Atlantic Ridge that divides the Eurasian and North American continental plates.

Icelandic Meteorological Office geologist Hjorleifur Sveinbjornsson told Reuters that Grimsvotn had thrown a plume of white smoke about 15km (nine miles) into the air.

"It can be a big eruption, but it is unlikely to be like last year," he added.

Iceland's Isavia airport authority said a flight ban of 120 nautical miles had been imposed around the area.

Glaciologist Matthew Roberts: the eruption "shouldn't have any far-reaching effects"

"We close the area until we know better how the ash is going to work," she spokeswoman Hjordis Gudmundsdottir.

Domestic airline Icelandair said no traffic had been affected.

"We do not expect the Grimsvotn eruption to affect air traffic to and from the country in any way," said communications director Gudjon Arngrimsson.

Last year's outpouring of ash from Eyjafjallajokull led to the largest closure of European airspace since World War II.

About 10 million travellers were affected and some questioned whether the shutdown was an over-reaction.

However, a scientific study published last month said the safety concerns had been well founded.

Researchers from the University of Copenhagen and the University of Iceland said ash particles from the early part of the Eyjafjallajokull eruption were especially abrasive, posing a possible threat to aircraft.

Titlu: Europe On Alert For Icelandic Volcanic Ash

Citat :
Airlines began cancelling flights to Britain late on Monday because of an ash cloud from an Icelandic volcano reaching its airspace, although experts expected no repeat of travel chaos from an eruption a year ago.

Britain's Met Office forecast the plume of ash from the Grimsvotn volcano would cover the Irish Republic, Northern Ireland, Scotland and parts of northern England by 0600 GMT on Tuesday.

Worries about the effect of the ash cloud pushed forward US President Barack Obama's planned departure from Ireland and he arrived on Monday night in Britain to begin a state visit.

The Irish Aviation Authority said flights to and from Ireland could be disrupted later in the week but did not expect problems in the next 48 hours. Iceland's main airport reopened late on Monday, while other parts of Europe were on alert.

With the ash cloud approaching, airlines began cancelling flights over the UK, raising the spectre of big losses for airlines already facing sky-high fuel costs.

British Airways grounded all flights from London to Scotland until 2 pm (1300 GMT) on Tuesday as a precautionary measure, a spokeswoman said.

Flybe, easyJet and Aer Lingus all said they were cancelling some of their flights to and from Scotland on Tuesday.

Dutch airline operator KLM said on Monday night it had cancelled 16 flights flying to and departing from four British cities and scheduled for Tuesday. Fights to and from Aberdeen, Glasgow, Edinburgh and Newcastle would be cancelled on Tuesday morning, it said.

Iceland's aviation authority reopened Keflavik airport late on Monday, but said it was impossible to know whether the island's international hub would remain open on Tuesday.

"It is open now," spokeswoman Hjordis Gudmundsdottir said. "We will know tonight or tomorrow morning how it will go."

Last year, ash from an Icelandic volcano caused 100,000 flights to be cancelled, stranding 10 million passengers and costing the industry an estimated USD$1.7 billion in lost revenue.

Asked earlier on Monday if the ash cloud would cause some disruption to flights this time, a spokesman for Britain's Civil Aviation Authority said: "That's the way it's looking certainly at the moment."

Europe's air traffic control organisation said that if the volcanic emissions continued at the same rate, the cloud could reach western French and northern Spanish airspace on Thursday.

President Nicolas Sarkozy is due to host Obama and other G8 leaders in France later this week.

Authorities have backed more relaxed rules on flying through ash after being criticised for being too strict last time.

"I think the regulators are a bit more sensible than they were last year," Michael O'Leary, chief of budget airline Ryanair said. "We would be cautiously optimistic that they won't balls it up again this year."

Nevertheless, airline shares fell between 3 to 5 percent.

German Transport Minister Peter Ramsauer said he did not expect the Icelandic eruption to disrupt air traffic to the same degree as last year. But he added that there would be a flight ban for jets should particles from the ash cloud reach a concentration higher than 2 milligrams per cubic metre.

Speaking to Sky News, British Transport Secretary Philip Hammond said authorities could work with airlines to "enable them to fly around concentrations of ash rather than having to impose a blanket closure".

Grimsvotn erupted on Saturday and smoke funnelled 20 km (12 miles) into the sky. The eruption is the volcano's most powerful since 1873 and stronger than the volcano that caused trouble last year.

But scientists say the type of ash being spat out is less easily dispersed and winds have so far been more favourable.

"The difference in impact on aviation comes down to three factors: the ash being produced by the eruption, the weather patterns blowing the ash around, and new rules about planes flying into ash," University of Edinburgh volcanologist John Stevenson wrote on his blog.

SMOTHERED IN ASH

Some were expecting problems, however. "It's too early to tell if Europe will be affected. What's certain is that when it is affected, there will be flight cancellations," French Transport Minister Thierry Marianai told Europe 1radio.

Airlines as far away as Australia were monitoring the cloud. Norway's civil aviation body said the one or two flights a day to the Arctic archipelago of Svalbard would shut Monday night. A small part of Greenland's eastern air space was also closed.

The Icelandic Met Office said on Monday night the eruption had abated slightly since Sunday, with the ash cloud at 5-9 km elevation in the previous few hours. But it also said that volcanic activity remained strong and steady.

The volcano lies under the Vatnajokull glacier in southeast Iceland, the largest glacier in Europe. People living in districts close by have been smothered in ash.

"Yesterday between 2 and 3 (in the afternoon) it brightened up a bit until 8 in the evening, then it became black again," said Sigurlaugur Gislasson, 23, whose family owns a hotel near the town of Kirkjubaejarklaustur.

"It is like being in a sandstorm," he said. All the tourists who were staying at the hotel have gone, he added.

Citat :
Ash from a massive plume of smoke from an eruption of Iceland's most active volcano could spread south to parts of Europe during the week. Here are a few facts on volcanic eruptions:

THE DANGERS:

-- VOLCANIC GASES - The most dangerous gases released during an eruption are sulphur dioxide, carbon dioxide and hydrogen fluoride. High concentrations of sulphur dioxide injected into the atmosphere by large explosions can result in lung ailments, acid rain, lower surface temperatures and depletion of the earth's protective ozone layer. When carbon dioxide, which is heavier than air, settles in low-lying areas or collects in the soil, it can be lethal to people and animals.

-- ASH FALL - Large volumes of ash can settle on buildings, resulting in their collapse. High levels of ash particles can cause increased coughing and irritate the eyes and skin and sometimes result in serious lung conditions. When the acid coating on ash is removed by rain, it can pollute local water supplies and damage vegetation. On the other hand, ash deposits can be beneficial by improving the fertility of soil.

-- PYROCLASTIC FLOWS - An avalanche of hot ash, rock fragments and gas can flow down the side of a volcano at speeds of up to 240 kph (150 mph) during explosive eruptions, burning everything in its path. People on the margins of the flows can suffer serious injury or even death from burns and inhalation of hot ash and gases.

-- VOLCANIC ERUPTIONS IN HISTORY:

-- Pompeii was buried under a deep layer of ash in an eruption of the Vesuvius volcano, which towers over the Bay of Naples in southern Italy, in AD 79.

-- In 1815 the Tambora volcano eruption in Indonesia killed an estimated 92,000 people. It has been claimed that volcanic ashes swept all the way to Europe blanketing the continent in a veil and turning 1816 into a "year without summer."

-- In 1883 Krakatoa erupted in Indonesia killing 36,000. The impact of the eruption spewed molten rock and sulphate aerosols into the atmosphere. The debris in the atmosphere created vivid red twilights in Europe between November 1883 and February 1884 - a fact reflected by painters of the period.

-- An earthquake measuring 9.5 struck the coast of central Chile in May 1960, triggering tidal waves and volcanic eruptions. Some 5,000 people were killed.

-- Mount Pinatubo, 80 km (50 miles) north of Manila erupted in June 1991 killing more than 700. Some 200,000 buildings were destroyed.

-- The Mount St. Helens volcano in the US state of Washington erupted in May 1980, creating a cloud of ash 4,000 km (2,500 miles) long and 1,600 km (1,000 miles) wide. The eruption was triggered by a 5.1 magnitude earthquake. 57 died.

-- In June, 2006, eruptions at Mount Sakurajima, on the southern Japanese island of Kyushu, spewed volcanic gases 2 km (6,600 ft) into the air.

-- An explosion from the 1,500-metre (5,000-ft) summit of Bulusan volcano in June 2006 in the Philippines sent ash and steam 1 km (3,300 ft) into the air.

-- In April 2010 an eruption from below the Eyjafjallajokull glacier in Iceland hurled a plume of ash six to 11 km (3.8 to 7 miles) into the atmosphere.

-- The eruption caused chaos when it erupted. Authorities halted flights due to fears that dust and ash would get into aircraft engines. In mid-April much of European air traffic was grounded for nearly a week. Airlines had to cancel around 100,000 flights, stranding millions of passengers.

-- Grimsvotn lies under the Vatnajokull glacier in southeast Iceland, the largest glacier in Europe. When it last erupted in 2004 trans-atlantic flights had to be re-routed south of Iceland, but no airports were closed. -- Authorities have banned flights close to the Grimsvotn volcano. but an official said the eruption was not expected to affect European airline traffic in the next 24 hours.

Citat :
Scottish regional carrier Loganair has become one of the first outside Iceland to be affected by the latest episode of volcanic ash problems, announcing the cancellation of 38 flights on 24 May.

The carrier, which operates as a franchise of larger UK regional airline Flybe, operates a network of services from Edinburgh and Glasgow to destinations in northern Scotland and the Northern and Western Isles.

The cancellations affect all Loganair services between 06:00 and 13:00 on 24 May, with the exception of its network of inter-island flights in the Orkney Isles.

Passengers booked on flights after 13:00 on 24 May should consult its website for further updates, it said.

With major disruption looming, the carrier has added several additional flights for the evening of 23 May to help passengers who want to travel ahead of the stoppage.

Loganair said that its latest information was that the ash cloud would persist over Scotland throughout the day, clearing progressively on the night of 24-25 May.

More European airlines have cancelled their flights to and from Scotland as the Icelandic ash cloud makes its way southwards.

British Airways, Aer Lingus, Ryanair, easyJet, Flybe, Jet2 and British Midland International (BMI) have cancelled their flights today to Glasgow, Aberdeen, Inverness and Edinburgh.

KLM has also cancelled flights to Newcastle, which is close to the Scottish border. In addition, BMI has cancelled its flights to Stavanger in Norway.


Ryanair said it strongly objected to the Irish Aviation Authority's (IAA) advice to not operate flights to Scotland and added that it will seek a meeting with IAA to have the restrictions removed.

Three airports in Scotland, namely Glasgow International, Aberdeen and Edinburgh are still open despite the flight cancellations by the airlines, says airport operator BAA.

Citat :
Aproximativ 500 de zboruri au fost anulate marti in Europa din cauza trecerii, prin nordul Marii Britanii, a norului de cenusa provocat de eruptia vulcanului islandez Grimsvotn, a anuntat marti organizatia europeana pentru securitate aeriana, Eurocontrol.

"Astazi, zone cu o concentratie puternica de cenusa au trecut prin anumite regiuni din nordul Marii Britanii", a subliniat organizatia intr-un comunicat, potrivit Mediafax.

"Prin urmare, aproximativ 500 de zboruri au fost anulate din cele circa 29.000 care erau prevazute in toata Europa", a adaugat aceasta, intr-o prezentare a situatiei realizate la ora 15.00 GMT (18.00, ora Romaniei)."Exista o probabilitate mare ca norul de cenusa sa atinga anumite parti ale Danemarcei, sudul Norvegiei si sud-vestul Suediei pana maine (miercuri)", a subliniat Eurocontrol.

"Acest lucru ar putea avea un anumit impact asupra traficului aerian, dar cu noile proceduri aplicate si deplasarea preconizata a norului in cursul ultimelor zile, impactul real asupra zborurilor ar trebui sa fie relativ redus", a adaugat aceasta.

Comisia Europeana a anuntat de asemenea, marti, ca nu se asteapta la perturbari importante, contrar situatiei din urma cu un an.

Europenii trebuie sa se pregateasca "pentru o saptamana foarte dificila pentru pasageri si companiile aeriene", a declarat comisarul pentru Transporturi, Siim Kallas. Dar "nu anticipam o inchidere de mare amploare (a spatiului aerian) de tipul celei de anul trecut", a adaugat el.

"Cenusa (vulcanica) este diferita, conditiile meteorologice sunt diferite, iar raspunsul european este diferit", cu o coordonare consolidata intre autoritatile nationale, carora le revine decizia de a inchide sau nu spatiul aerian, a precizat el.

Citat :

Compania aeriana British Airways a efectuat un zbor "de proba" intr-o zona considerata de catre Oficiul britanic de Meteorologie ca fiind contaminata cu cenusa vulcanica. Zborul BA 9271E al aeronavei A320 nu a avut la bord pasageri, echipajul fiind alcatuit din doi piloti si doi observatori ai departamentului de inginerie din cadrul companiei aeriene, potrivit The Guardian.

Echipajul format din doi piloti si doi ingineri ai companiei aeriene British Airways (BA) a zburat la diverse altitudini in nordul Marii Britanii, intr-o zona considerata de catre expertii de la Met Office ca fiind afectata de catre norul de cenusa vulcanica. In afara de doua camere care au inregistrat densitatea norului de cenusa, la bord nu au existat alte echipamente speciale de monitorizare.

Directorul departamentului de inginerie al BA, Garry Copeland, a declarat ca, in timpul zborului de 45 de minute in care s-a incercat "cartografierea" spatiului aerian britanic cuprins intre Manchester, Newcastle, Glasgow, Edinburgh si Londra, nu au fost identificate dovezi de poluare vulcanica. In urma zborului, motoarele aeronavei, echipate anterior cu filtre noi, au fost inspectate cu o camera video telescopica (de felul celor folosite in chirurgia laparoscopica). Nu au fost gasite urme de cenusa vulcanica.

Inainte de decolare, expertii companiei au dat asigurari ca nu vor exista urme de cenusa, in ciuda previziunilor Oficiului de Meteorologie (Met Office).

Copeland a adaugat ca pilotii BA sunt instruiti pentru evitarea cenusei, intrucat aeronavele pe care le piloteaza zboara adesea pe rute unde eruptiile vulcanice reprezinta un potential pericol. "Atunci cand este vizibila, cenusa vulcanica apare sub forma unui nor intunecat. Pe timp de noapte, poate fi identificata dupa mirosul sulfuric sau dupa anumite indicatii de electricitate statica", a explicat Copeland.

British Airways spera ca rezultatele acestul zbor de proba vor duce la redefinirea zonelor considerate afectate de catre norul de cenusa vulcanica, permitandu-le companiilor aeriene sa zboare prin zone care sunt, de fapt, necontaminate. "Intentia este sa gasim modalitati de a continua operatiunile in conditii de siguranta", a spus Copeland.

Cel mai activ vulcan din Islanda, Grimsvotn, a inceput sa erupa din nou sambata (21 mai), iar autoritatile au luat masura de inchidere temporara a spatiului aerian pe teritoriul tarii. Ultima eruptie a vulcanului, care se afla sub ghetarul Vatnajokull in sud-estul tarii, a avut loc in 2004.

Mai multe aeroporturi din Marea Britanie au fost inchise din cauza norului de cenusa vulcanica. Marti (24 mai), autoritatile au anuntat ca cenusa a ajuns in dreptul Scotiei si ca se va extinde in Tara Galilor, nordul Angliei si Irlanda de Nord, apoi in mare parte din restul Marii Britanii.

Meteorologii islandezi sustin ca exista "semne clare care arata ca eruptia a incetat cu adevarat" si ca "nu a mai fost detectat fum care sa iasa din vulcan".

Ministrul Mediului, Laszlo Borbely, a declarat miercuri ca norul de cenusa provenit de la vulcanul islandez nu va ajunge in Romania pana joi (26 mai) dupa-amiaza.

A cloud of volcanic ash will reach the north of the Czech Republic by midday on Wednesday, with ash concentrations staying thin and causing no disruptions in air traffic, an official said.

"The thin concentrations that will come here will not affect traffic in the Czech Republic," the head of the Air Navigation Department at the Czech Hydro-Meteorological Institute Bohumil Techlovsky said.

"The high concentrations will definitely not get here today nor the following two to three days," he said.

The cloud will slowly move on towards the east, with its main part looming above the country's territory until around midnight, Techlovsky added.

Citat :
Iceland's volcanic eruption has died down and is no longer spewing out ash, officials said on Wednesday and airlines began to get back to normal after cancelling about 1,000 flights in northern Europe.

European air traffic agency Eurocontrol said it expected the ash cloud would dissipate overnight and did not see any significant disruption to travel in Europe on Thursday.

The explosion of the Grimsvotn volcano on Saturday caused much less chaos than an eruption last year at another Icelandic volcano thanks to new rules for airlines, but the incident showed problems remain with the regulations. Budget airline Ryanair was vocal in its criticism.

Hrafn Gudmundsson, a meteorologist at the Icelandic met office, said that mainly steam was coming from the crater, with no ash plume detected since 0300 GMT.

"There are indications that it's ceasing really," he said.

University of Iceland geophysicist Pall Einarsson said it was unlikely, though not impossible, that the volcano would begin disgorging significant amounts of ash again.

"At this stage we can at least hope for the worst to be over in terms of ash production," he said.

"At the moment there is practically no ash being produced and what little there is being deposited on the glacier that is immediately around the crater."

After the eruption, the most powerful by Grimsvotn since 1873 and stronger than the one at Eyjafjallajokull that caused air traffic chaos last year, a massive plume of ash spread across northern Europe.

Flights in Scotland and northern England were cancelled on Tuesday, while four German airports -- Bremen, Hamburg and Berlin's Tegel and Schoenefeld -- closed on Wednesday only to be reopened hours later.

Dutch airline KLM resumed flights to affected destinations after a brief break.

Eurocontrol said about 450 flights were affected in Germany following a similar number of disruptions a day ago across northern Europe.

"Tomorrow, we do not expect any significant impact on European airspace," it said.

Eurocontrol had earlier said the ash could drift to Poland, but a Polish air traffic control official said no traffic limitations were due.

US President Barack Obama, who left Ireland early on Monday to travel to Britain to avoid being caught by the ash, is due to arrive in Poland later this week.

The ash cloud from Grimsvotn belched 20 km (12 miles) into the sky after the eruption, but did not trigger the kind of travel chaos caused by Eyjafjallajokull when more than 10 million people were hit by a six-day European airspace shutdown.

Grimsvotn's eruption did expose disarray among the authorities who decide on aviation safety as they try to apply new rules to avoid another mass closure of European airspace.

PATCHWORK

New procedures put the onus on airlines to make judgments on whether it is safe to fly through ash, in coordination with the forecasting authorities, particularly the Volcanic Ash Advisory Centre at the British Met Office, and civil aviation bodies.

Sources said a British research plane designed to sample ash remained grounded for a second day in a wrangle over its deployment.

Ryanair on Tuesday said it had safely sent two planes into what authorities had deemed high ash zones over Scotland, and criticised "bureaucratic incompetence."

International Airlines Group CEO Willie Walsh also said his company had flown a plane into an ash zone. "The simple answer is we found nothing," he told BBC radio.

He called for the British authorities to use multiple sources of data when deciding on how to react to ash problems.

"The potential for a patchwork of inconsistent state decisions on airspace management still exists," IATA Director General Giovanni Bisignani said in a statement, calling on Tuesday for more coordination.

Grimsvotn is Iceland's most active volcano.

Though the Open University's David Rothery expressed optimism this eruption was over, he added: "However, it will be back - next week, next year, or more likely next decade."
