Catching mantle plumes by their magma tails

Hawaii's volcanos stand as silent sentinels. They guard the secret of how they formed, thousands of miles away from where the edges of tectonic plates clash and generate magma for most volcanos. A 2017 Nature study by Jones ...

CT scan of Earth links deep mantle plumes with volcanic hotspots

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 ...

Textbook theory behind volcanoes may be wrong

In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study from ...

New force driving Earth's tectonic plates discovered

Bringing fresh insight into long-standing debates about how powerful geological forces shape the planet, from earthquake ruptures to mountain formations, scientists at Scripps Institution of Oceanography at UC San Diego have ...

New explanation for Hawaiian hot spot

(PhysOrg.com) -- Scientists in the US have suggested that volcanic activity in Hawaii could be fed by a giant hot rock pool 1,000 kilometers west of the islands and in the Earth’s mantle, rather than being fed by a hot ...

Nature recycles trash to create diamonds

The Earth's deepest diamonds are commonly made up of former living organisms that have effectively been recycled more than 400 kilometers below the surface, new Curtin research has discovered.
