The so called Westfjords of NW Iceland form together a coastlinie with the same direction as the volcanic zones in the southern half of the country. It has been explained by Björn Harðarson that this is due to the fact that an extinct volcanic zone is found just outside the peninsulas of this coastline. There are so many things about geologic history you can see on an ordinary map!
The Westfjords and volcanic zones

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. View all posts by Steingrimur Thorbjarnarson
