Is this the system of volcanos that seriously gassed Europe in the 1700's?
"Foul-smelling gases from a volcanic eruption in Iceland are pestering the region, reaching Norway and Finland more than a thousand kilometers away.
Unusually high concentrations of volcanic gases from the continuing Holuhraun eruption have been detected as far away as Finland. In Iceland, health authorities are urging locals near the volcano to stay inside due to significant levels of sulfur in the air."
