Researchers from China and Japan have discovered distinct characteristics of Earth's lower mantle flow field. They investigated seismic anisotropy ... of mantle plumes, which are two major styles ...

"We have known for years that these islands are located at the boundary between the Earth's core and mantle. And we see that seismic waves ... mantle plumes, which are large bubbles of hot ...

Seismic tomography is a powerful tool to investigate the dynamic of the Earth's interior. In the last 10 years, the resolution of whole mantle seismic models has improved (Ritsema et al., 2011; Moulik ...
