In some posts here, it is postulated that similarities can be found between the Strandir area in NW Iceland and the East Fjords. Marking the extinguished volcanic sites of the NW with circles and comparing with the East, it actually fits. Extinguished volcanic sites are found at the same locations, at first sight beyond sheer coincidence.
The old volcanic sites of the NW compared with the East Fjords. Drawn on map base from Náttúrufræðistofnun (The Icelandic Institute of Natural History).
The parallel origin of these areas seems to lead to a similar distribution of volcanic sites. This is by no means a thorough comparison, as this is just to point out an idea for those interested in geoscience to compare those areas.
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.
