Eruption in Iceland caused cold-spell in Europe

New research shows that the eruption in Eldgjá in 934 was much more powerful than the 1783 Lakagígar eruption. The Eldgjá eruption caused great changes in weather conditions, famine, a cold-spell and epidemics in Europe and the Middle-East. Geologist Haukur Jóhannesson tells Iceland State Radio, RÚV that geologists have been researching effects of volcanic activity on climate change. Geologists say that volcanic activity on Reykjanes is likely to occur sooner than later.
