In 2009, Iceland drillers hit 1,000°C magma by accident, unlocking a geothermal source that could produce nearly 10 times more power

In 2009, a drilling operation in northeast Iceland unexpectedly punched into molten rock at Krafla, revealing one of the hottest geothermal resources ever reached by a borehole. The Iceland Deep Drilling Project(IDDP) had been searching for high-temperature geothermal energy, but instead of finding only hot water and rock, the drill encountered magma at about 2.1 kilometres below the surface.
