Iceland trembles: Largest volcanic eruption in Grímsvötn in 100 Years

May 22, 2011Iceland – The current volcanic eruption in Grímsvötn on Vatnajökull glacier is the largest in that volcano 100 years and larger than the one in Eyjafjallajökull last year. It is similar to the eruption of 1873, according to geophysicist Magnús Tumi Gudmundsson. A large flood is not expected. This morning the ash cloud was 15 to 18 kilometers high which means that the volcanic eruption is ten times more powerful than the last eruption in Grímsvötn in 2004, Gudmundsson told However, it is not unique. Grímsvötn goes through phases where it erupts often in a period of 60-80 years, then there are quieter periods of equal length. In these quieter phases there are small eruptions such as the ones in 1998 and 2004 and then the third and fourth eruption are larger in scale, like in 1619 and in 1873, which is similar in character as the one we’re experiencing now. It is much larger with much more magma flow and much more emission of ash than what we witnessed in the volcanic eruption in Eyjafjallajökull last year. The ash scatters widely and the ash cloud stretches over a large part of the country. –Iceland Review

    The Super Volcanoes are next.


    • Some of them are long overdue. The ash cloud is now slowly moving over Reykjavík, big, brown and reather nasty looking, just closed all windows and covered my instruments, this stuff goes everywhere.


  2. Jens Skapski says:

    Bye Bye airplanes!


  3. Amethyst Newbridge says:

    So now is there any word on air traffic disruptions? This is a caldera type volcano I believe. Just wondering if the ash cloud would be the same composition as eyjallafjallajokull’s and, is there any word on Katla stirring?


  4. Dennis says:

    Oh Lord! In last years eruption of a Volcano in Iceland, Western Europe had a massive disruption of its Air Passenger Service and parts of Iceland was coated in ash destroying crops and disrupting lives. I wonder if we will see similar results from this.


  5. luisport says:

    From other forum, but it’s interesting: However we just had an extra news bulletin 10 minutes ago. A veteran pilot who has flown over 23 volcanic eruptions here has just said he has never seen such a big eruption. His grandparents lived through Katla and he imagines that this might be similar.

    They did say on Rúv News that this eruption was about 10x larger the Eyjafjallajökull volcano eruption in the year 2010. But I do not know how accurate this news is at this moment.


  7. luisport says:

    UK Met Office: ash cloud from Iceland could hit Scotland by Tuesday and rest of UK by Friday, if eruption continues at same level


  8. Mahati says:

    You can follow the news here
    Magnús Tumi Gudmundsson, professor of Geophysics at the University of Iceland says the Eruption in Grímsvötn seems to be getting smaller. Still, ash is falling in many places in the southeastern part of Iceland…..

    Local updates! We went this morning at 5am to Kirkjabaerklustur, after only 3 hours of sleep. The last explosion at 2am was pretty amazing as observed from Selfoss. Also the lightnings. In morning, the ash column was hidden in a vast cloud visible in all eastern horizon. As we got there it was very scary, it was pitch black in Kirkjabaerklustur, and locals told me they never experienced this in any Grimsvotn eruption. The ash fall is very heavy. Already 5cm or more of ash there. We only stayed 30min it was impossible to stay longer, as conditions were getting worse. We left and ash fog is already about 2hours from Reykjavik, and moving southwestwards. Now, I am back home, there is a huge cloud over the east horizon covering about 20% of the sky (this is 150-200km away), and inside the ash column is visible, moving southwards. News reports spoke of 23km high column or more. I will report more later, now I am going to have a rest!!

    Something else. Local news reported also that possibly large amounts of lava are being released and they were a little bit afraid of a fissure eruption. But everything is still unclear.

    So far, there is no indication of anything else outside the large activity around the central caldera of Grimsvotn!

    Two key facts remain: this is at least the tallest ash column since 1947 Hekla, biggest Grimsvotn in 100 years, and seems visually bigger than the Eyjafjallajokull eruption last year. Lets see what happens

    Any official confirmation that Hamarinn has also erupted now in unison with Grimsvotn? Hamarinn being located to the west of the Vatnajokull glacier.


  11. luisport says:

    Ash falling in the town of Selfoss

    Selfoss is 30 miles from the capital Reykjavík

    Selfoss population 6500

    Reporters from Channel 2 flew up on the glacier by @grimsvotn volcano with Incredible scenery.


  13. luisport says:

    I read in Portuguese news that the ash cloud is allready in the aerial space of Canada!


  14. Kim says:

    My mind is blown by this everything is heating up and everything is seriously 100 years, 1000 years or the headlines say ‘worst’ floods, drought, tornadoes, strange natural events, amazing events in the Heavens, etc. Everything is either the worst or setting a new record and didnt 2010 set new records too like during the winter and than this winter too. volcanoes everywhere are erupting, people can no longer afford to close their eyes to what is happening on the planet. It’s affecting every place.

    God Bless


    • Nickie says:

      You would think people would open their eyes, but for some people it takes a bomb going off, – & I can hear the bomb ticking VERY loudly……


      • Kathy says:

        Some skeptics, I know, seem to be hearing the bombs going off too. I think many people are aware, but don’t want to have their lives disrupted, by the truth.

        God bless us all and may He open everyones eyes.


    • J Guffey says:

      Those that reject Christ will never believe even the obvious.
      2 Corinthians 3:14 But their minds were hardened. For to this day, when they read the old covenant, that same veil remains unlifted, because only through Christ is it taken away.
      God bless you and all the others that are trying to make the blind see what is so obvious to us.

    There is something cooking beneath the earth and above it by mother nature for us. We have reached the point where mother nature is taking her revenge. The scientists and our Governments have messed with mother nature for a very long time and these are signs of her revenge.
