Fagradalsfjall (Reykjanes Peninsula, Iceland): (24 Jul) The University of Iceland’s Institute of Earth Sciences reported a summary of eruption parameters today documented since 26 June. Parameters showed lava area, lava volume, lava flow discharge rate, rock geochemistry, and volcanic gases. The graph below depicts an overview of the results.
The current eruption’s site activity changed at the end of June as it began to fluctuate a lot in the frequency of lava flow discharge rate’s periods. Following measurements depict a decreasing level of the lava flow.
