Looking at the grid of division lines of convection rolls, along with the division line within the tectonic plate, we can see crossings exactly where the uplift is taking place.
Crossings between tectonic plates division and mantle rolls division lines on the Reykjanes Peninsula
The regular bow of tectonic division line from Hveragerdi to the Reykjans Ridge is mirrored around the point close to the Blue Lagoon and Grindavik.
I have a BS degree in geology, BA in anthropology, graduated in Chinese language and as a certified tourist guide. I provide this website about my contribution to answer the greatest question remaining about our Earth. I have analyzed the convection rolls within the Earth's mantle and how they affect the surface. This makes it possible to provide many interesting examples about geology found on my blog.
