Slow - moving seismic waves, hotter than surrounding material, interact with plumes rising from the mantle to affect the formation of
hotspot volcanic islands.
Not exact matches
University of California, Berkeley, seismologists have produced for the first time a sharp, three - dimensional scan of Earth's interior that conclusively connects plumes of hot rock rising through the mantle with surface
hotspots that generate
volcanic island chains like Hawaii, Samoa and Iceland.
They slow down the seismic waves caused by earthquakes and may be the culprit for deep mantle plumes, which can lead to
volcanic hotspots like those that created Yellowstone National Park or the Hawai'ian
Islands.

Island in the Indian Ocean rise from an unusually primitive source deep beneath the Earth's surface, according to new...

island in its place.
Known as
hotspots,
volcanic island chains such as Samoa can ancient primordial signatures from the early solar system that have somehow survived billions of years.

volcanic hotspot that formed Réunion
Island in the Indian Ocean rise from an unusually primitive source deep beneath the Earth's surface, according to new work in Nature from Carnegie's Bradley Peters, Richard Carlson, and Mary Horan along with James Day of the Scripps Institution of Oceanography.
The
island's volcanism is associated with the rifting along the Azores Triple Junction; the spread of the crust along the existing faults and fractures has produced many of the active
volcanic and seismic events, [22] while supported by buoyant upwelling in the deeper mantle, some associate with an Azores
hotspot.
