Eyjafjallajökull Glacier Volcano Continues to Eject Dense Plume of Ash


Iceland’s Eyjafjallajökull volcano continued to emit a dense plume of ash and steam on May 7, 2010. The plume extends southeast from the volcano, but curves south beyond the lower edge of the image. The large image, which includes a wider area, reveals that the ash is blowing over the Atlantic Ocean west of Ireland. On Iceland, low-level winds pick up ash that had settled on the land. This plume of resuspended ash blows south from the island. The higher-elevation volcanic plume casts a dark shadow on the lower-elevation resuspended ash. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on May 7, 2010. Image and caption: NASA E/O. Download large image (3 MB, JPEG)

Eruption in Eyjafjallajökull Status Report: 16:00 GMT, 07 May 2010

The following is a brief summary of the report:

  • Decrease in explosive activity since yesterday.
  • Plume height lower (7.6km max), ash color lighter.
  • Steam still rising from lava front under Gígjökul.
  • Large ash fallout reaching up to 60 km from the crater.
  • No sign eruption might be  ending.
  • Earthquakes are occurring at 5-13 km depth, frequency of occurrence lower than yesterday.
  • Surface deformation stabilized since yesterday.
  • Only 5 % of particles smaller than 10 micron (aerosols)

Eyjafjallajökull Eruption Portents Catastrophic Sequence

Posted by feww on April 26, 2010

Three Reasons Why the Moderators Believe a  Sequence of Catastrophic Eruptions May Occur in Iceland

  1. It would be consistent with the resurgence of volcanic activity globally, which may have started recently.
  2. Historically, the eruptions at Eyjafjallajökull have been associated with subsequent eruptions at a larger volcano, usually Katla.
  3. Volcanic eruptions are a component of the planet’s defense mechanism.

In our opinion, the question is no longer “if” but “how soon” a cataclysmic event, or indeed a series of events would occur.

The answer, we believe, is found in EDRO Collapse Model.  As of 2010, Google Civilizations are about half way through the human-induced antiphase.

Status Update:

Eruption at Eyjafjallajökull continues unabated. No significant change reported since previous update.

Lava finally flows from Icelandic scientific band

Posted by feww on April 25, 2010

Lava flows northwards from the Eyjafjallajökull crater, melting the glacial ice: Report

The local experts do not believe large-scale flooding could occur from the melt water, but then again …

Oh, and if you are wondering why everyone in Iceland is suddenly speaking about lava flow in the past tense, you’re not alone. The rascals didn’t tell anyone lava had started flowing 4 days ago!

Notice: The following updates were issued by various Icelandic organizations. Unlike the govt organizations in the US, nearly all of the  information broadcast by government organizations and educational outlets in Iceland and most European countries may be subject to copyright. If your use of their data goes beyond the educational use/ fair use, be sure to contact the authors for copyright clarification/ permission.

Department of Civil Protection and Emergency Management -Media team

Specialists from the Institute of the Earth Sciences (http://www.earthice.hi.is/ ) and the Icelandic Meteorological Office (http://www.vedur.is) flew over the eruption site in Eyjafjallajökull late yesterday. The lava flow seems to be of similar volume as in recent days (20-40 tons per second). The quantity of the volcanic plume is slowly decreasing. The flow of lava is most likely to have started near noon on April 21 when water started flowing continuously from Gígjökull. Steam plumes rose from the northern edges of the caldera after noon on that day and could be seen from a helicopter. Deflation associated with the volcanic tremor was noticed at the same time. There are no signs of melting or flow of water to the south. There are also no indications that the eruption is coming to an end.

There are still disruptions in domestic and international flights, according to information from ISAVIA, and passengers are therefore strongly advised to seek further information from air carriers and at: http://www.textavarp.is/ .

Icelandic Met Office Report

Eruption in Eyjafjallajökull, Iceland

Indications of lava flow to the north – 25 April 11:30

Yesterday evening, geophysicists from the Institute of the Earth Sciences found indications of lava flow from the eruption site. The risk of sudden melt water flow is, however, minor. Following is their description:

“North of crater a roughly 300 m long and wide depression has been melted out in the last three days. Steam plumes rise from the depression, especially at the margins. This is explained by lava flowing northwards from the crater with the steam rising where lava meets ice … Flow of lava is considered to have begun around noon on Wednesday 21 April.”

Icelandic Meteorological Office and Institute of Earth Sciences, UoI

Eruption in Eyjafjallajökull – status report 25 April 2010 at 1800

Eruption plume:
Height( a.s.l):  Unknown, not seen above cloud cover at 5.3 km.
Heading:  NW
Tephra fallout:  Minor (light fallout detected at two farms 10 km NW of vents)

Conditions at eruption site: Overall activity similar as yesterday.  Eruption seen from west in the morning – north crater still active.  External water has not affected vent activity much since 18 April.  Geologists field observations (2-10 km from vents) show that explosivity is magmatic and that the tephra produced since 18 April is much coarser than during first four days.  Explosions heard at Fljótshlíð, 10-15 km NW of vents.   Meltwater discharge suggest similar lava activity.  Processing of data obtained yesterday shows that lava had advanced 400-500 m northwards from crater, forming an ice depression extending some 700 m from vents.

Overall assessment:  Magma flow rate has remained at similar level over the last few days.  Plume activity is gradually declining.  Flow continues flowing towards north.  No signs of melting or meltwater discharge towards south.  No signs of termination of eruption.Eruption in Eyjafjallajökull – status report 24 April 2010 at 1700
Eruption plume: Height( a.s.l): 13000 feet (4 km)
Tephra fallout: Minor (plume dark but no reports of fallout in districts around volcano)
Meltwater: 100-120 m3/s, based on gauge at old Markarfljót bridge and a rough estimate of base flow.
GPS deformation: Indicates slow subsidence towards the center of the volcano.
Magma flow: Eruption plume: less or equal to 10 tonnes/s.
Lava flow: 10-30 tonnes/s
Total magma flow: 20-40 tonnes/s

Eyjafjallajökull Eruption – UPDATE 24 April

Posted by feww on April 24, 2010

Comparative Calm Before Explosive Storm?

A Powerful Earthquake May Strike Iceland

The Plume at Eyjafjallajökull Rises to a Height of about 7,000m Sporadically, Idling Mostly at 4,000m

Fire Earth Moderators believe the volcano is spewing more ash than it did 2-3 days ago, despite the local reports.

Eruption in Eyjafjallajökull, Iceland -Update on activity
Little changes – 24 April 2010 11:15

Volcanic tremor has been similar as the last 2-3 days.
Ash fall may be expected to the west and northwest from the eruption, minor in the Reykjavik area.
Water level in Markarfljót river is slightly higher than yesterday.

The Department of Civil Protection and Emergency Management, Media team, released the following bulletin earlier today:

News Release, 24 April 2010, 06:30

According to the Hvolsvöllur police, this was a quiet night. A little ash has fallen on Hvolsvöllur, and it is visible as a very fine dust on cars. The Weather Bureau expects strong winds from the northeast and the east along the southern coast, elsehwhere the winds will be softer and there will not be much precipitation. The ashen mist will probably move to the west and the northwest of the volcano, even reaching Reykjavík, but only in slight quantities

In a news release from the Chief Epidemiologist yesterday, it appears that wen ash mist occurs, or an increase in suspended particulates in the atmosphere, those who suffer from a dormant heart og lung disease are advised to remain indoors, but there is no call for using masks. It is expected that the eruption-related suspended particulates pollution in the capital area might be close to a similar pollution caused by traffic, and the warnings issued by health authorities will be in accordance with such pollution. The public should keep track of news and information and instruction on the websites of the Department of Civil Protection and Emergency Management, http://www.almannavarnir.is, and of the Environment Agency, http://www.ust.is .

According to information from the airports, air traffic is limited to and from Keflavík, Reykjavík and Akureyri at the moment. No IFR-permissions are issued for Akureyri Airport, but the Egilsstaðir Airport is open to all flight traffic. Further information will be released later this morning.

The information centre for the media at Hvolsvöllur (tel. 847-4846) will remain open during he week-end. A press representative will be there, but there will be no meeting with specialists at 8 am. On the other hand, such meetings will be held at the information centre in Skógarhlíð from 08:00 til 09:00 am, Saturday and Sunday. Today, geophysicist Sigurlaug Hjaltadóttir, from Iceland Weather Bureau, Árni Snorrason, director of the Weather Bureau, and Árni Birgisson, director of the airport and guiding dept. of  Isavia, will answer questions conveyed by the media and press agents.

Eyjafjallajökull Ejects ‘Lava Lumps’

Posted by feww on April 20, 2010

Eruption at the Eyjafjallajökull

Eyjafjallajökull has been ejecting “lumps of lava”  from the volcano crater in the glacier in the past few hours, local geo-scientists have reported.

Meanwhile, Icelandic Meteorological Office reported that ashfall in the capital Reykjavik was unlikely. The risk is mitigated by easterly wind, blowing the ash away from the capital area, and rain forecast which could reduce the risk of ashfall.

Direct observations of Eyjafjallajökull showed  that lave was being splattered out of the volcano. The volcanic plume reached a height of about 3,000m (10000 feet), peaking to about 5,200m (17000 feet).

The local experts reported the plume as being  mostly white, “but with very dark pillars of smoke” blending in. “According to the Icelandic Meteorological Office website, the plume rose up to 4000 meters at 8:50 this morning. A lower plume indicates that water cannot enter the crater and that lava has begun to flow into it.”A report said.

There was no report of lava flows from the volcano, as of posting.

Ash Cloud Over Europe

Weather patterns continue to blow vast pockets of ash towards the UK and Ireland.

The UK Met Office, which is the North-west European Volcanic Ash Advisory Centre with responsibility for issuing the Volcanic Ash Advisories for volcanoes erupting in this area, said their priority and role is provide information that would support decision-making by NATS, CAA and other aviation authorities .

“It is for the aviation industry and regulator to set thresholds for safe ash ingestion. Currently, world-wide advice from ICAO is based on engine and airframe manufacturers stating that aircraft should not be exposed to any volcanic ash.” It said.

The above is an illustration of volcanic ash dispersion up to 20,000 ft, issued at 7 am on 19 April. Advisory charts are issued every six hours, for up to 18 hours ahead, by the Volcanic Ash Advisory Center.

Ash cloud from Eyjafjallajökull reached  Canada’s Eastern seaboard

“The ash cloud is very diffuse, moving slowly and should not affect Canadian airports,” said an Environment Canada spokeswoman.

A forecaster at UK’s Met Office said it was unlikely that the ash would drift much further into North America.

“It is just skirting into the Newfoundland area over the next 12 to 18 hours. It doesn’t look as if it is going to get much further west than that, just on the coast and a little further inland.” He said.

Newfoundland is the closest tip of North America to Iceland.

Eyjafjallajökull Volcano Cauldron – Satellite Images

Posted by feww on April 19, 2010

Eyjafjallajökull Volcano Cauldron and Ash Plume  Seen in NASA Satellite Images


Visible (left) and infrared (right) images of Iceland’s Eyjafjallajökull volcano, acquired April 17, 2010, from the Hyperion instrument onboard NASA’s Earth Observing-1 (EO-1) spacecraft. Image credit: NASA/JPL/EO-1 Mission/GSFC/Ashley Davies

In the left-hand image, created from visible wavelengths, new black ash deposits are visible on the ground, as well as nearby brilliant unsullied ice and snow and the volcano’s brown, billowing plume. The plume’s dark color reflects its large ash content. These fine particles of pulverized rock are carried high into the atmosphere, where they create a hazard for aviation and are carried long distances by the prevailing winds.

In contrast, the false-color, infrared image at the right reveals the intense thermal emissions (at least 60 megawatts, or 60 million watts) emanating from the vent at the base of the massive plume. This thermal emission, equivalent to the energy consumption of 60,000 homes, represents only a small proportion of the total energy being released by the volcano as its molten lava interacts violently with ice and water. Each image covers an area measuring 7.7 kilometers (4.8 miles) wide, and has a resolution of 30 meters (98 feet) per pixel. The vertical direction is north-northeast.

Eyjafjallajökull Eruption Intensifies

Posted by feww on April 17, 2010

Webcams Show Heightened Activity

Eruption at Eyjafjallajökull has steadily Intensified in the past 3 hours

Eyjafjallajökull has resumed explosive activity in the past 3 hours, having earlier slowed down to sporadically ejecting single plumes of ash once every 2 to 3 minutes.

The following are latest images obtained from two webcams that are trained on Eyjafjallajökull at Valahnúk and Hvolsvelli stations. The images show a constant stream of ash, steam and fumes spewed from the Icelandic volcano.The images are provided by Míla ehf and may be subject to copyright.


Valahnúk Webcam freeze frame of Eyjafjallajökull at 08:55UTC .


Hvolsvelli Webcam Image of Eyjafjallajokull also recorded at 08:55UTC.

The following irregular sequence of images were recorded from Hvolsvelli Webcam.


[L-R and T-B] Freeze frames shows a large plume of ash, steam and gasses ejected from the volcano just after sunrise at 5;16UTC on April 17, 2010. The ash plume seen in the first frame above dispersed (second frame) within minutes of being ejected from Eyjafjallajokull; however, after a series of explosions that occurred about 30 seconds later, another plume was ejected out of the volcano’s crater. The new plume seemed to be slightly larger than the previous one. Click image to enlarge.

Another sequence of images recorded simultaneously from Hvolsvelli and Valahnúk Webcams.


[T – B] The above freeze frames were recorded at about 5:31UTC, showing single plumes of ash and gasses ejected from

Eyjafjallajökull – UPDATE Apr 17

Posted by feww on April 17, 2010

Eyjafjallajökull Still Erupting

40,000 flights grounded since Thursday to avoid engine failure from Eyjafjallajökull ash

A new round of flooding has affected the areas around Eyjafjallajokull, as hot gases from the volcano continue to break up and melt the glacier that covers it.

Huge volumes of floodwater and massive chunks of ice, some reportedly as large as 3-story apartment blocks, have forced about 1,000 locals to evacuate their homes, most of them for a second time in 3 days. The floodwaters have almost completely washed off a causeway along the flooded Markarfljot river, which was severely damaged in the first round of flooding.

According to a local report,  the eruption is somewhat weakening, and Eyjafjallajökull is producing less ash, for now.

Eyjafjallajökull Eruption – UPDATE Apr 16

Posted by feww on April 16, 2010

A Time to Reflect!

Much volcanic activity may occur in Iceland during the coming months: Eyjafjallajökull, perhaps Katla, Laki and others … even Jan Mayen their northerly neighbor could kick in keeping more flights grounded

Eyjafjallajökull Eruption Has Grounded Flights Across Much of Europe for a Second Day

As the eruption at Eyjafjallajökull volcano continues unabated, more smoke and ash from the glacier-filled volcano in Iceland drifts into Europe’s airspace, affecting up to a million air passengers. The disruption could continue into the weekend and beyond.

As of posting, up to 8,000 flights have been canceled since a no-fly zone was declared in northern Europe on Thursday.  The airspace from as far west as the Republic of Ireland to Finland and was Western Russia are now closed. The countries that are directly affected and whose airspace have been shut down are: Republic of Ireland, Norway, UK, Netherlands,  Belgium, Denmark, Sweden and Finland.

Additionally there is a partial or planned no-fly zones currently operating in the northern airspace of three  other countries: France, Germany and Poland.

How long Will the Eruption Last?

“It is likely that the production of ash will continue at a comparable level for some days or weeks. But where it disrupts travel, that depends on the weather,” Einar Kjartansson, a geophysicist at the Icelandic Meteorological Office, told the reporters.

The last time the subglacial volcano erupted, it went on ejecting ash for a period of two years, from 1821 to 1823.

Ash Drifting Very Slowly

In the absence of wind the ash cloud is “progressing very slowly eastwards” and has remained “very dense,” the European air traffic control, Eurocontrol, has said.

“In general, the situation cannot be said to be improving with any certainty,”  the National Air Traffic Service in the UK was quoted as saying.

The European air traffic control organisation, Eurocontrol, said a lack of wind meant the ash cloud created by the volcano underneath Iceland’s Eyjafjallajoekull glacier was “progressing very slowly eastwards” and remained “very dense”.

In addition to the European airlines, at least 5 other long-haul airlines have canceled flights to Europe.

Eyjafjallajökull eruption melts glacier

Posted by feww on April 15, 2010

Katla volcano may be next in line to erupt: Fire-Earth

New volcanic eruption at Eyjafjallajökull melts Gígjökull  glacial tongue, causing extensive flooding in Markarfljót river, south of Iceland

Eruption at Eyjafjöll is consistent with recent global patterns of volcanism and tectonism. Wild eruptions may occur in Iceland and elsewhere—Fire-Earth [March 22]

Geologists who flew over Eyjafjallajökull glacier said a deep fault trough has occurred  around the crater below the summit of the glacier.

The gap measures about 500 meters, a report said. However, the geologists were unable to detect any vents or signs of eruption due to the cloud cover.

The eruption which occurred in the top crater, buried about 200m beneath the ice, ejected a large plume of volcanic ash that reached a height of about 6,700m (22,000 feet) and there was ash fall to the east of Fimmvörduháls.

The glacial river has flooded at a rate of about 1,000 cubic meters per second, a report said.

Air Traffic Suspended North of Norway

Norway has suspended air traffic in its northern airspace due to the threat of engine damage from the impact of volcanic ash that has traveled far covering a vast area after the eruption at Eyjafjallajökull glacier. The ash and smoke particles in the air have also reduced visibility considerably, a report said.

“We have closed the aviation area between Bodoe and Tromsoe and are considering closing the aviation area all the way south to Trondheim,” Sindre Aanonsen, spokesperson for the Norwegian air traffic control center said to reporters.

Fimmvörduháls Eruption

The eruption at Fimmvörduháls, which began on March 20,  has extended the height of the mountain by about 82 meters, geologists were reported as saying.

Eyjafjöll Eruption Update – April 3

Posted by feww on April 3, 2010

Serial No  1,532. If any posts are blocked in your country, please drop us a line.

Fimmvörduháls Eruption May be Intensifying – A Second Fissure Has Appeared

A new volcanic fissure has appeared near Eyjafjallajökull in southern Iceland to the northwest of the original fissure on March 31. It may be a sign that the eruption at Fimmvörduháls is intensifying.

A pilot on a sight-seeing flight observed the vent at about 7:00PM  on Wednesday (local time). He saw a sudden flash of light followed  by a new rift, which opened up immediately after, a report said.
