As the Reykjanes Ridge follows a mathematical formula, just follow the mathematics. On the surface, a shift is found eastwards for the volcanic activity, in the form of the volcanic zones of Iceland. But underneath, the effect of the Reykjanes Ridge convection rolls is felt.
These convection rolls become subducted south of Iceland, but still their existence is felt all the way to the surface within the context of the convection rolls system. It is curious that at one point, the same distance is found to the edges of the Icelandic Platform in the ocean, to the North and South, and East and West, respectively.
