Chemical fingerprints from volcanic rock offer hints of what’s happening in the mantle below the area where three rift zones ...
A spot in eastern Africa called the Afar Triangle marks the meeting point of three rift zones—lines where Earth’s crust is being rent apart. Researchers haven’t been sure exactly what drives this ...
The largest volcanoes in Earth’s history owe their formation to powerful geological phenomena called mantle plumes—upwellings of abnormally hot rock within the Earth’s mantle that rise toward the ...
In East Africa's Afar Depression, scientists have discovered that fresh lava from deep within the Earth's mantle is driving ...
Like the volcanoes found on Hawaii and Iceland, those on Easter Island are driven by an underlying "hotspot," a plume where molten material rises through the mantle like paraffin wax floating up a ...
Magma from deep within the Earth's mantle can surge through a volcano in a matter of months rather than thousands of years or more, as previously thought, according to a study published Wednesday ...
Iceland is one of the most active volcanic regions in the world, but its seismic nature is part of a much broader geological ...
A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...
Mysterious Blobs in Earth’s Mantle Are ‘Like a Map’ for Volcanic Eruptions “In the past 250 million years, 80 to 90 percent of large eruptions are located around the edges of the blobs.” ...
A 2021 eruption in Iceland gave researchers rare and illuminating access to the mantle, one of the Earth’s layers. ... volcanic eruptions occur when lots of small magma flows mix together.
The volcano appears to have been created by material rising up from a region deep beneath Earth's surface—the transition zone. The transition zone is the region between the upper and lower mantle.
