The two main lowland areas are marked on this map:
The outlines of the lowlands are obvioulsly marked by the convection rolls division lines.
The Reykjanes Ridge uppermost division line does cross the geothermal area of the West, whereas the large geothermally active area of the South is found mainlu within a triangle, north of the South Iceland Seismic Zone (and within it), inside the polygon of the Southern Lowlands.
I have a BS degree in geology, BA in anthropology, graduated in Chinese language and as a certified tourist guide. I provide this website about my contribution to answer the greatest question remaining about our Earth. I have analyzed the convection rolls within the Earth's mantle and how they affect the surface. This makes it possible to provide many interesting examples about geology found on my blog.
