This panoramic view shows Laki craters or Lakagigar, a volcanic fissure in the south of Iceland. Laki craters spread tons of basalt lava in the surroundings when they opened up in the 18th century. The eruption happened in 1783 and lasted eight months, pouring out an estimated 14 km³ (3.4 cu mi) of lava. The ashes and sulfur dioxide emitted by the eruption had a global influence on the weather that lasted several years.
