What you wrote, is a good place to start future observations. There is a lot of unexplored dynamics to investigate, in the earth. Roiling hot fluid and gaseous systems in flux, which are magnetic - due to iron (and other minerals), is a fluid dynamics dream subject. But, how to finance? In today's research systems driven by funding to support specific answers, instead of expanding knowledge just to see what we learn.

Ps. An attempt at modeling the inner Earth's systems and flows might be more useful for earthquake prediction.
