Iceland - May 23rd, 2011

This image shows a cloud of ash spewing from Iceland’s Grimsvotn volcano, a vision reminiscent of the 2010 eruptions of the Eyjafjallajökull volcano (click here for previous articles). The Grimsvotn volcano is located under the Vatnajokull glacier in the Vatnajokull National Park – the biggest national park in Europe.

Although the eruption temporarily affected European air travel, with about 700 flights cancelled in Germany on Wednesday, air traffic is now operating normally. In Iceland, clean up of the ash has begun, and all major roads have been reopened.

Eyjafjallajokul Volcano Sends Ash Due East – May 13th, 2010

Despite the clouds covering most of Iceland and the surrounding ocean, the location of the volcano Eyjafjallajokul is easily pinpointed at the origin of the plume of ash. At the time this image was taken, winds were blowing the ash due east.

On May 11th and 12th, the volcanic ash cloud from Iceland reached the air space of Turkey as well as North African countries. Around 5 airports in Morocco were shut down as a precautionary measure due to the ash cloud.

The ash cloud from the 2010 Iceland volcano also closed airspace over Southern Spain, which caused airports to be shutdown in some Spanish Islands. Turkey affected by the volcanic ash as previously mentioned, but 2 airports were functional in Istanbul.

Eyjafjallajokul Volcano in Ireland Wreaks Havoc with European Flights Once Again – May 11th, 2010 – UPDATE

Airlines canceled hundreds of flights across Europe and added hours to trans-Atlantic journeys once again Sunday as planes were diverted around a large  plume of ash spewed by the Eyjafjallajokul volcano in Iceland that stretched from Greenland to Portugal.

So far, the weekend cancellations have been a fraction of the flights nixed two weeks ago when jittery European air traffic authorities closed down much of the continent’s airspace for fear the volcano’s abrasive ash could harm jet engines. But the possibility loomed of continuing eruption, and rising costs to airlines from ongoing disruption.

The bulk of the cloud, measuring 2,100 miles long and 1,400 miles wide (3,400 kilometers by 2,200 kilometers), stretched over the North Atlantic, according to the Irish Aviation Authority. It ordered Ireland’s five westernmost airports to close Sunday afternoon but allowed the country’s three biggest airports in Dublin, Shannon and Cork to stay open.

Airlines diverted their trans-Atlantic traffic north and south of the cloud, causing congestion as planes tried to squeeze through remaining routes. Some connections were canceled entirely because of an offshoot of the main cloud that was snaking its way from Portugal through Spain, southern France and northern Italy, then up to Germany, the Czech Republic and Austria.

Daniel Gerstgrasser, a meteorologist with Switzerland’s national weather agency, said rain would help wash out the cloud by Monday morning and no further ash drifts were expected to reach the continent in the coming 24 hours, although this image, taken today, clearly shows ash still being expelled from the volcano.

Ash closes Irish, UK airports – May 4th, 2010

Airports in Ireland and parts of Britain were closed again for some hours on Tuesday because of the cloud of volcanic ash drifting south from Iceland that wreaked havoc on European air travel last month.

Flights in much of continental Europe were operating as normal and the Irish Aviation Authority (IAA) said it would allow flights to resume from Irish airports from 1200 GMT after a closure lasting six hours.

However, the IAA said northerly winds forecast for the coming days could bring more clouds of ash from the Icelandic eruption and disruption for passengers this week.

“We could be faced with this periodically during the summer,” IAA Chief Executive Eamonn Brennan said. “We are probably facing a summer of uncertainty due to this ash cloud,” Brennan said.

The IAA had closed airports from 0600 GMT until 1200 GMT due to risk of ash ingestion in aircraft engines, although overflights of Ireland from Britain and continental Europe had not been banned.

The UK’s National Air Traffic Services (NATS) said a no-fly zone was in place in the west of Scotland and Northern Ireland, from 0700 a.m. (0600 GMT) until at least 1300 (1200 GMT).

European flights overall were expected to be at almost normal levels on Tuesday, European air traffic agency Eurocontrol said.

On a typical weekday, just under 200 flights would be expected in and out of Ireland, compared with around 28,000 throughout Europe, a spokeswoman said.

Ash particles from Iceland’s still-erupting Volcano

Ash particles from Iceland’s still-erupting volcano remain high in the atmosphere and do not pose a health risk so far to people in Europe, the World Health Organization said on Tuesday.

Toning down its guidance from Friday, when it said the ash cloud that has grounded flights could be “very dangerous” for those with asthma and respiratory problems, the WHO said there was no cause for public health alarm so far.

“There are no effects on health at the moment, except in the vicinity of the volcano in Iceland,” Carlos Dora of the public health and environment division told a news briefing.

Icelanders living near the volcano should stay indoors or wear face masks and goggles to protect themselves against coarse particles that can irritate the lungs and eyes, Dora said.

The most dangerous ash particles are the smallest ones which can be breathed in deep into the lungs, and which have moved further from the volcano in the plume billowing over Europe.

But those fine particles are still “very high up” and weather conditions could very well cause the ash cloud to disperse without causing health problems in Europe, Dora said.

The World Meteorological Organization, based in Geneva, like the WHO is based in Geneva, said the ash particles were made up of small jagged pieces of rock, mineral and volcanic glass the size of sand, salt or silt. Such fine particles are normally dispersed by thunderstorms which are not expected in the region in the coming days.

A low pressure weather system is expected to develop over Iceland later this week, potentially pushing the cloud toward the Arctic and prompting rain to “wash out” the ash, the WMO said in a statement. A WMO expert said that the health risks of the cloud were currently negligible across Europe.
