Compare in Google maps Hekla and its counterpart 30° to the East. Why? Because the same convection cell pattern is found under the tectonic plates at 30° interval on the same latitude. Find the correct spot in Norway and compare to Hekla. The pictures look strikingly similar! Still, Norway is geologically not similar to Iceland at all. How can this be?
Hekla and Trondheim area – 30° of longitude apart compared
All this can easily be explained. So join the club!

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.
