Drilling Into Iceland Volcano
An attempt to drill into the heart of a volcano in the south-west of Iceland is now complete. Geologists have penetrated 4,659m down, creating the deepest-ever volcanic borehole. Their aim is to tap into the steam at the bottom of the well to provide a source of geothermal energy. They recorded temperatures of 427C, but believe the hole will get hotter when they widen it in the coming months.
