How Volcanic Island Chains Formed - Supercomputer Simulation | Video

Seismologists have traced the path of seismic waves to create a three dimensional scan of Earth's interior. According to UC Berkley researchers, it "connects plumes of hot rock rising through the mantle with surface hotspots that generate volcanic island chains like Hawaii, Samoa and Iceland."
