Porposal for Breiðdalur volcano Geopark

Breiddalseldstod snid

Picture by Martin Gasser 2016, with information from Walker 1963

Breiðdalur volcano was an active volcano around 9 millon years ago. It is situated between Berufjörður and Breiðdalur valley. Ice age glaciers eroded the landscape strongly. That makes it possible to see inside the extinct volcano. Report for proposed Geopark area here (the report is partly in English)

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:

pH 7,88                                                                                pH 3,19
Conductivity 643 µS/cm                                                      Conductivity 1325 µS/cm
The weather was northerly wind, rain and snow with short (<5min) periods of sunshine. The mountain tops were permanently in clouds.
