Location of the eruption on Fimmvörðuháls / Eyjafjallajökull
Monday, March 22nd, 2010The volcanic eruption on Fimmvörðuháls (next to Eyjafjallajökull) has attracted a lot of attention, but precise data and visualizations of the fissure location have been hard to find.
But I did find data on the location, length and orientation of the fissure in this news article on ruv.is (Icelandic), and that location seems to fit well with an infra-red satellite photo on the Institute of Earth Sciences website. This location and orientation also seems to match the helicopter photos taken this evening — it does seem like the pictures are not taken under as large an angle of incidence as the helicopter’s height would imply, but I suppose that’s hard to eyeball. So this location is probably a fair guess.
I put together the following in Google Earth:
- this estimated position of the fissure (guessing a length of 750m lengd, in the middle of the 0.5-1km range given on ruv.is).
- the locations of Baldvinsskáli (mountain hut) and Básar (end of the hiking trail) based on Google Earth map imagery
- two GPS trails (trail 1, trail 2) posted by travelers on Wikiloc
- the coordinates of the helicopter TF-SIF when the three photos on the Coast Guard website were taken this evening
The fissure appears to lie right across the Fimmvörðuháls hiking trail, on the Brattafönn (Steep Snow) slope.
Here is a KMZ file for Google Earth with this data, and below is an overview photo of the data, and a close-up showing the fissure crossing the hiking trail.

Enjoy, and please let me know if some of this can be corrected/improved.
