Beneath Earth's surface, scientists find long "fingers" of heat
September 5, 2013
Scientists seeking to understand the forces at work beneath the surface of the Earth have used seismic waves to detect previously unknown "fingers" of heat, some of them thousands of miles long, in the Earth's upper mantle. Their discovery, published Sept. 5 in Science Express, helps explain the "hotspot volcanoes" that give birth to island chains such as Hawaii and Tahiti.
