a "Print Screen" of it, same position. Alas, I've got the jpeg on my job computer. Boris! As far as climate-affecting Icelandic eruptions are concerned and on historic evidence, aren't the Laki and Eldgj fissures far more likely than Katla to produce such eruptions (even if some sites claim Eldgj is a part of the Katla system)? Also, how do we know the 1912 Novarupta eruption was "low on SO2? so to speak? Direct observations or inferred from a lack of climatic effects?
