Hotspot volcanoes

model of Earth’s interior reveals clues to hotspot volcanoes | Earth

Scientists at the University of California at Berkeley have detected previously unknown channels of slow seismic waves in the Earth’s upper mantle, a discovery that helps explain the “hotspot volcanoes” that give rise to chains of islands like than Hawaii and Tahiti. Unlike volcanoes that emerge from collision zones between tectonic plates, hot spot volcanoes […]

New model of Earth’s interior reveals clues to hotspot’s volcanoes

Scientists at UC Berkeley have detected previously unknown channels of slow seismic waves in the Earth’s upper mantle, a discovery that helps explain the “hotspot volcanoes” that give rise to island chains such as Hawaii and Tahiti. This 3D view of the first 1,000 kilometers of the Earth’s mantle under the central Pacific shows the […]
