New research published this week on the evolution of volcanoes sheds light on what lies deep beneath the Earth's surface. The research, published in Nature, suggests that the plume of hot material that provides Hawaii's volcanoes with its continuous supply of molten lava originates from a depth of almost 3000 km, at the border between the Earth's core and its rocky mantle. This is far deeper than had been thought possible by many scientists.
