There are a few hotsprings in Iceland named Geysir. One is world famous and its name became used in general for spouting hot springs. The hot spring area of Geysir in Haukadalur of SW Iceland shows resemblance of Geysir at Hveravellir in the NE.
Here is a picture of the hot spring Strokkur in the area of Haukadalur.
Strokkur in Iceland
Both Geysers are located close to the main division line of lower mantle.
The two Geysir areas
The geothermal areas are known to have a distribution from SW to NE. The mantle division lines pattern is not known to almost everyone, so therefore this symmetry compared to the convectin rolls is shown here.
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.
