Eyjafjallajökull Eruption – MODIS Image – UPDATE May 8

Posted by feww on May 8, 2010


See Below for details.


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 volcanic ash cloud shuts 15 airports in Europe

As the 2,000km (1,200mile) ash cloud further encroaches into European airspace, targeting tourist destinations, more  airport closures expected in northern Portugal and southern France.

List of the airports that have been affected, as of posting, includes Asturias, Bilbao, Burgos, La Coruna, Leon, La Rioja, Pamplona, Salamanca, San Sebastian,  Santander, Santiago, Valladolid, Vigo, Vitoria and Zaragoza.

UK’s Met Office said the Icelandic volcano was sending ash up to heights of 9.1km (30,000 ft ) at about 10:00UTC today.

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!

Specialists from the Institute of the Earth Sciences ( ) and the Icelandic Meteorological Office ( 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: .

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.”

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,, and of the Environment Agency, .

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.

Lava from  Fimmvörduháls crater on a mountain pass in south Iceland has changed direction the Hrunagil canyon into the Hvannárgil canyon forming a spectacular 100-meter high lava fall.

“There is a continuous flow of lava,” geophysicist Magnús Tumi Gudmundsson told Morgunbladid. The lava flow now extends to about one kilometer from the fissure.
