Eyjafjallajökull and Hekla

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:

Eyjafjallajökull in 1995 (from the SE) 

Fig.1 Eyjafjallajökull the glacier from under which the current eruption is occuring.

The snout of Gigjökull 

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.

The 1980 Hekla eruption

The Hekla 2000 eruption. 

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.
