According to the analysis presented here, equator and the parallel of 64°N have mathematically identical outcomes. Even though the rotation provides much more angular velocity at equator, special things appear at 64°N as well.
Some would just show some reflex and start talking about something else, but there is a reason for this.
The division lines between mantle convection rolls have a long term guiding effect for the tectonic drift, leading to these results.

I am a geologist, graduated from the University of Iceland, and taught geology for a few years. I have gained some knowledge about Earth's inner structure, so I provide this website as my contribution to answer one of the greatest questions remaining within the realm of geoscience. Experiments show that the mantle should form convection rolls when close to the melting point. I took this literally, and calculated the dimensions and shape of these mantle convection rolls. Then I compare that model with the surface. This makes it possible to provide many interesting examples about geology found on my blog.
