Iceland's six-month-long volcanic eruption was over for less than a week when geologists clambered onto the cooling lava lake in Baugur crater to measure toxic gases there. [Read the full story.]
Baugur crater was the tallest and largest in the long chain of craters built by the spectacular fire fountains that exploded from the earth on Aug. 31, 2014, in remote central Iceland. The magma feeding the eruption comes from Bardarbunga volcano, located some 28 miles (45 kilometers) to the southwest. Here are some of the stunning views from inside Baugur crater on March 4, 2015.
The surface eruption, called the Holuhraun lava field, ended on Feb. 27, but volcanic gases still stream from the cooling lava. Scientists from the British Geological Survey and the Icelandic Meteorological Office plan to monitor the emissions for several months. Sulfur dioxide pollution from the huge lava flow could still reach hazardous levels in Iceland, the Met Office has warned.

The surface temperature inside the crater is still a red-hot 1,110 degrees Fahrenheit (about 600 degrees Celsius). The same scientists as in the previous photo are visible as cool purple figures, as seen with a thermal camera. (Photo credit: Evgenia Ilyinskaya/British Geological Survey)
