How did researchers pinpoint the location of the 1831 volcanic eruption, and what were the previous misconceptions?

Analysis of ice cores revealed a six-and-a-half times higher concentration of sulfur deposits in Greenland than in Antarctica in 1831, indicating a large eruption in the Northern Hemisphere's mid-latitudes. Geochemical analysis of ash and volcanic glass, coupled with computer modeling, pinpointed the source to the Zavodovsky volcano. This finding corrects the previously held belief that a tropical volcano was responsible.
