New study shows that ash cloud in Eyjafjallajökull and Grímsfjall volcanoes eruptions larger then expected

It was reported on Rúv News today about a new study that came out few days ago. In this study according to Rúv News the ash cloud from Eyjafjallajökull (2010) and Grímsfjall (2011) volcanoes where larger then appeared on satellite images. Meaning the ash could was covering larger area then appeared on images from space. The grain size in this eruptions was also underestimated. The decision to close down the airspace as was done in both eruptions was correct.

More details can be found here.

  1. There is no question about how large Grimsfjall’s 2011 episode was. Paul Einnerson commented about it. EQ’s are slowly increasing but this is normal behavior, I believe.

    1. Indeed, some very deep ones beneath Hábunga.

      Anyone got any links to median filtered tremor guages for Mýrdalsjökull they could share?

      2. Great, thanks. I tried various possibilities on the basis of inferences I had made but none of them came up with the goods.

      3. GOD is not good for monitoring the deep intrusions below habunga. I reccomend HVO, RJU or partially ALF.
