Supercomputing the Clues to Hotspot Volcanos

Researchers are using supercomputers at to detect previously unknown channels of slow-moving seismic waves in Earth’s upper mantle. This discovery helps to explain how “hotspot volcanoes”—the kind that give birth to island chains like Hawaii and Tahiti—come to exist.

Simulating the Earth’s Core with the Cray XE6 Monte Rosa

Researchers at ETH Zurich and the University of Leeds are using supercomputers to learn why the Earth’s magnetic field moves gradually westward.
