Comparing convection rolls and real time events is one aspect of looking into the details of the magma currents. Earthquakes along the line extending from the Reykjanes Ridge follow very similar pattern. The earthquakes occur on lines crossing the RR extension line. The green stars show earthquakes over 3 on Richter scale.
Earthquakes compared with convection rolls division lines.
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.
