Langisjór is a world of its own, and so important to geology. As it is a very long feature, about 20 km, it shows the main alignment of the relevant volcanic zone quite well. The world’s mantle convection cells are arranged according to the formula used here, and it is exhibited quite clearly at Langisjór:
The accuracy is a proof that this is the correct way to compare surface features with the system of convection currents underneath, as shown in a previous post about Langisjór.

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.
