Africa-Press – Rwanda. <\/strong><\/span>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.<\/p>\n

Researchers from Arizona State University (ASU) have managed to gain new insight into the so called large low-shear-velocity provinces (LLSVP) \u2013 two humongous blobs of rock located deep within our planet\u2019s mantle.<\/p>\n

According to Live Science, the researchers\u2019 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.<\/p>\n

Having examined some 17 global seismic wave data sets, Qian Yuan and his adviser Mingming Li, who is a geodynamics assistant professor at ASU, have determined that the LLSVP beneath Africa extends about 1,000 kilometres higher than the Pacific LLSVP.<\/p>\n

Yuan also argued that, since the African LLSVP appears to be much taller than the Pacific LLSVP, it must be a lot less dense as well. With LLSVPs suspected of being the source of hot plumes of mantle material rising up, Yuan suggested that such plumes may cause calamities such as supervolcano eruptions or even possibly a continental breakup.<\/p>\n

He noted that, with the African LLSVP being \u201cvery close to the surface,\u201d there is a possibility that \u201ca large mantle plume may rise from the African blob and may lead to more surface rising and earthquakes and supervolcano eruptions.”<\/p>\n
