Center of Earth (IMAGE)
Caption
Tomogram of the lowermost mantle (on top of core-mantle boundary, such as in our paper) centred on the equatorial region north of Australia. Green dots are stations and red dots are earthquakes near the Earth’s surface, the Earth’s mantle is transparent, and the ray paths through the interior are shown by solid lines. This image was made by our NCI Vizlab facility based on my data and the tomographic model of the lowermost mantle. You can see that the stations and earthquakes used in the tomographic inversion are not uniformly distributed across the surface.
The blue regions are the regions of high velocity and the red regions show the low velocity.
