Traveling along the 64th parallel in Iceland is fascinating. It is the latitude of volcanoes, from Hengill with two power plants at its side to Hekla, Laki and Öraefajökull volcano. And why is this latitude so active? It is one of the topics I deal with and have explained by referring to the convection current system.
The topic 64°N

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
