Mývatn – a complicated hub of mantle convection

Near Mývatn are the high temperature areas of Krafla, Námaskarð and Bjarnarflag. At Bjarnarflag the Nature Baths are found.

The reason is a complicated network of division lines between convection rolls of different layear below the area.

The location of Mývatn coincides with a small polygon formed between convection rolls division lines

At Námaskarð, very special formations are found like this one:

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.
