Laki lava is a type of volcanic rock formed from the eruption of basaltic lava. It is primarily found in Iceland, where the famous Laki fissure erupted in 1783, releasing a massive amount of lava and gases. This event had significant environmental impacts, including climate changes that affected agriculture in Europe. The Laki eruption produced a vast landscape of lava fields, creating unique geological formations. The lava flow from this eruption covered approximately 600 square kilometers and is known for its distinctive features, such as deep cracks and rugged terrain. Today, Laki lava is studied for its geological significance and its role in understanding volcanic activity.
