Beerenberg in Jan Mayen is in the line of the Eastern Volcanic Zone of Iceland! It has to be calculated with the formula for the polar system of convection cells. It looks like that:
Looks complex? It is not, because you do not need the formula to see how the famous Laki is in the same line as Beerenberg. The same convection cells are at work underneath both volcanic sites! The location of the volcanic sites can be explained by referring to the convection rolls of the mantle.

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.
