| Plumes From Earth's Mantle Could Cause Supervolcano Eruptions, Continental Breakdown
"This instability can have a lot of implications for the surface tectonics, and also earthquakes and supervolcanic eruptions..." by Andrei Dergalin via Sputniknews Image: CC BY-SA 2.0 / Argonne National Laboratory / Composition of Earth's mantle The new research suggests that the two large low-shear-velocity provinces, located beneath Africa and the Pacific respectively, differ in how close to the surface of the planet they extent. Researchers from Arizona State University (ASU) have managed to gain new insight into the so called large low-shear-velocity provinces (LLSVP) – two humongous blobs of rock located deep within our planet's mantle. According to Live Science, the researchers' findings indicate that one of the blobs, which resides beneath Africa, extends far closer to the surface and is more unstable than its counterpart that sits on below the Pacific.
