The Eldgjá eruption is the largest basalt lava flood of the Common Era. It has been linked to amajor ice‐core sulfur (S) spike in 939–940 CE and Northern Hemisphere summer cooling in 940 CE. Despite itsmagnitude and potential climate impacts, uncertainties remain concerning the eruption timeline, at...
