Hazard mapping news

Freysteinn Sigmundsson, Erik Sturkell and I presented preliminary results of our hazard mapping project for Snæfellsjökull at the Natural Science Symposium (Raunvísindaþing) in Reykjavík in March. Have a look here for the abstract and here for an image of the poster. Feel free to contact me for more information or for a pdf file of the poster which should be clearer.

In May we (Freysteinn, Ármann Sigmundsson and I) begin a new project, funded by Landsvirkjun, modeling tephra fallout from Hekla. This will involve collating information of past eruptive and weather conditions during activity at Hekla and resultant tephra fall patterns and characteristics. We will combine this information in a GIS system, as we have done for volcanic phenomena at Snæfellsjökull, and carry out modeling of tephra fallout and sedimentation patterns. I am impressed with how useful it has been to use a GIS system to combine and analyse spatial as well as temporal data in these hazard mapping projects and look forward to applying process-related modeling to further tailor our hazard assessments to specific eruptions scenarios, which we intend will make them much easier to interpret and understand in the event of a future eruption.
