Jan Mayn is a part of the same volcanic structure as Iceland. It can be shown by pointing out the pair of convection rolls connecting the highest volcano of Iceland, Öræfajökull, with the volcano of Jan Mayen, Beerenberg.
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.
