These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found lurking below Africa and the Pacific Ocean, entombed some 1,200 miles below the ...

New study questions whether the continents, North America and Europe, ever completely split apart tens of millions of years ...

When these plumes reach the surface, they result in volcanoes forming, spewing forth lava like they recently have in Hawaii and in Iceland. "We think that those mantle plumes originate at the ...

But Iceland is also located over a mantle plume – a column of hot, molten rock that rises from the deep mantle to the surface, becoming lava when it erupts. However, unlike recent eruptions in ...

Barbara Romanowicz, a professor at the University of California at Berkeley, will give a talk titled "Mantle Plumes Rooted at the Core-mantle Boundary: Evidence from Seismic Waveform Tomography" at 11 ...

The good news is that because the top of the volcano is still 4,500 feet below the ocean’s surface, it poses no danger to ...

For centuries, we have been taught that there are seven continents, but new research has suggested there are actually only ...

New research from scientists at the University of Hawaii at Manoa, which was published in the Journal of Petrology last month, indicates the two shield volcanoes share a magma source within Hawaii’s ...
