A long time ago, in a land, far, far away, I did a Ph.D on the remote sensing of Icelandic icecaps. Afterwards, I acquired some AVHRR imagery over Iceland to help a former colleague look at secondary desposition of tephra. So I though I’d dig out some old photos and some old images:
Fig.1 Eyjafjallajökull the glacier from under which the current eruption is occuring.
Fig.2 The snout of Gigjökull taken from Eyjafjallajökull. The glacier has retreated a great deal since this picture was taken in 1995. There is now a pro-glacial lake instead of the glacier.
Fig.3 The ash cloud generated by Hekla in 1980. The image is from the Advanced Very High Resolution Radiometer (AVHRR) band 4. Image courtesy of the Dundee Satellite Station.
Fig.4 The 2000 eruption of Hekla imaged by AVHRR band 4 (mid-IR). Image courtesy of the Dundee Satellite Station.
As you can see from Fig 3 & 4 previous ash clouds have tended not to head immediately south!
More to follow at a later date.
