Video: Stunning 'CT scans' of the Earth's interior reveal vast plumes under the ocean feeding volcanic hotspots

Seismologists have produced the first a sharp, three-dimensional scan of Earth's interior that show exactly how volcanic island chains like Hawaii, Samoa and Iceland were created.

They conclusively connects plumes of hot rock rising through the mantle with surface hotspots that generate volcanic island chains.

Researchers say they are a 'CT scan of Earth's interior.'
