).
These numbers could be compared with the largest gas-rich eruption occurred in Iceland in 1783-1784
(
Laki eruption) and lasted 8 months. It has been estimated that during that eruption up to 122 Mt of SO2
were released into the atmosphere. Assuming a constant gas flux during the 8 months, the
Laki eruption
injected ~51 Mt in 100 days (5 - 15 times the Holuhraun‘s amount).
