Researchers have used “state-of-the-art numerical modeling techniques” to properly explore the huge underground structures hidden deep in Hawaii.
Thanks to university-led research, detailed images of certain ultraslow zones (rock regions with very low seismic velocity, located at the boundary between the Earth’s core and the mantle) were obtained for the first time. Of Cambridge.
The ultra-slow zone in question is almost directly below Hawaii, about 3000 kilometers below the surface.
“Of all the deep internal features of the Earth, these are the most fascinating and complex. We now have the first solid evidence of their internal structure. This is the Deep Earth Earthquake. It’s a true milestone in scholarship, “said Zhi Li Phys.org, a doctoral student at the University of Cambridge, who is a researcher in earth sciences and the lead author of research.
As the media points out, the images of the core-mantle boundary structure that scientists obtain using seismic waves from earthquakes are “grainy and difficult to interpret,” so the research team said, “The latest numerical modeling techniques. Revealed the kilometers using the scale structure located at the boundary mentioned above. “
Dr. Kuangdai Leng, co-author of the study that developed this method at Oxford University, said: ..
The results obtained by the team suspected that the zone contained much more iron than nearby rocks. “This iron-rich material could be the remains of ancient rocks on Earth,” said project leader Dr. Sanne Cottaar of Cambridge Earth Sciences. Early history, or even its iron, can be leaking from the core by unknown means. “
New research may also help shed light on “creating a chain of volcanoes like the Hawaiian Islands and what’s beneath them,” as the media press states.
