Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland met with a big surprise: underground lava, also called magma, flowed into the well at 2.1 kilometers (6,900 feet) depth.
It forced the scientists to stop drilling.
"To the best of our knowledge, only one previous instance has been documented of magma flowing into a geothermal well while drilling," said Wilfred Elders, a geologist at the University of California, Riverside, who led the research team

Elders and his team studied the well within the Krafla caldera as part of the Iceland Deep Drilling Project, an industry-government consortium, to test whether geothermal fluids at supercritical pressures and temperatures could be exploited as sources of power, said Leonard Johnson, program director in NSF's Division of Earth Sciences, which funded the research.
"We were drilling a well designed to search for very deep--4.5 kilometers (15,000 feet)--geothermal resources in the volcano," said Elders. "While the magma flow interrupted our project, it gave us a unique opportunity to test a very hot geothermal system as an energy source."
