The NASA Earth Observatory is doing a superb job in speedily bringing us stunning images of the Eyjafjallajökull eruption from space. Some recent highlights:

Is there a possibility that the Eyjafjallajokull volcano is a (albeit small) supervolcano like Tambora in Indonesia or Yellowstone in Wyoming?
There is so much tephra material ejected, that I think it unlikely it came from just one volcano or a small reservoir underneath the crater. It must have been bigger than normal.
I would like your comments, please.

I am no scientist by any means but I was wondering that myself. I thought that once that large earthquake hit Chile that there would be an eruption somewhere. Whether it is linked I have no idea. I think that there may be a possibility that it could be a small supervolcano I guess only time will tell…

3. admin - 20 April 2010

Surely a small supervolcano is a contradiction in terms? In any case the term ‘supervolcano’ is a media invention that doesn’t have any real scientific validity. There is definitely nothing unusual about the size or eruptive behaviour of Eyjafjallajokull, or anything remarkable about the amount of material erupted. This volcanic eruption really has nothing in common with huge caldera events such as Tambora, or a potential eruption of Yellowstone.

4. JOHN PERSIJN - 20 April 2010

The Icelandic volcano Eyjafjallajokull at this moment erupting is of the Strato Volcano type such as Mt Mayon (Philippines), Mt Fuji (Japan), Krakatoa (Indonesia), Mt Agua (Guatamala) and Tavurvur (Papua New Guinea).
Perhaps as we don’t see this very often we tend to enquire. Thanks to Admin to let us know that this is nothing unusual, apart from the last time it erupted was in 1823. Perhaps the Haiti earthquake has triggered something in that region further north, and not the Chile one as Nikki G suggested. How long it will last is anybody’s guess.

Are we in a phase of increased seismic activity? Or is it just that these events are occuring in regions of large populus and there effects are impacting on the western world?

6. admin - 21 April 2010

There’s no evidence that there is more seismic activity now than in previous periods of the Earth’s very long tectonic history. It’s just that because of modern communications we hear about quakes these days that we would never have known about three hundred years ago. The point you make about expanding populations is also a good one: there are more people affected as population numbers rise and cities expand.

The same question was being asked about seismic and volcanic activity in the mid-nineteenth century, when a combination of telegraphs, steamships, railways and the expanding press was bringing news of these events within hours or days of their occurrence, when previously news would have arrived weeks or months afterwards, if at all.

WOW these photos are amazing and scary, I hope and pray that this doesn’t ever happen again. My prayers are with everyone that has been affected with this terrible disaster.

8. John Persijn - 15 May 2010

Eyjafjallajokull is till erupting todate, May 15th, and it might do so for a considerable time. And its activity is increasing again!! Is it possible, that one day in the very near future Mr Katla will join it in a Plinian eruption (like that of Vesuvius) or a Santorini disaster??
What if any could be done to avoid a tsunami reaching Northern Ireland or the Scottish Islands?? Is there a tsunami warning system in place in the North Atlantic??
