SAMPLING IN NORÐFJARÐARGÖNG tunnel, August 7th 2014 Vegagerðin and Breiðdalsseturin collaboration for sampling rock of the tunnel section, kept at Breiðdlassetur for further research. The research for the tunnel construction is built on research done by George P.L. Walker and his students. The staff of  Breiðdalssetur is organizing and taking samples regularly in the tunnel.

Caves in East Iceland

Geologist of Breiðdalssetur measured and mapped three caves in East Iceland by wish of locals: Skriðnahellir close to Borgarfjörður eystri in May 2016, Þjófahola in Álftafjörður in June 2016 and a cave on Fljótsdalsheiði in September 2017. Martin Gasser is an experienced speleologist. The results are visible below:

Right: The landslide was producing probably 4 tsunami waves in lake Askja. Luckily the hazard happened at night, when noone was around, picture by ​Gunn­ar Víðis­son.
A geologist from Breiðdalssetur went to lake Askja on 30th of July to take a further look on the landslide and the tsunami wave marks of the 21th July.
With a pH & EC meter from Náttúrustofa Austurlands, the pH and conductivity in Víti and Öskjuvatn were measured:
