Laki, a volcanic fissure in Iceland, erupted between June 1783 and February 1784, spewing out massive amounts of basalt lava and toxic gases. The aftermath was disastrous, with over 50% of Iceland's livestock dying and a fifth of the human population perishing due to famine. The eruption also caused a drop in global temperatures, leading to crop failures in Europe and potentially affecting weather patterns in Africa and Asia. Overall, Laki's impact was widespread and devastating, leaving a lasting mark on both Iceland and the world.
