Hallarmúli with the same chemistry as Hekla – and originated from the same site according to measurements

Hallarmúli has similar composition as Hekla according to Haukur Jóhannsson and Kristján Sæmundsson (http://www.isor.is/sites/isor.is/files/Jar%C3%B0fr%C3%A6%C3%B0i%20og%20gossaga%20vestara%20gosbeltisins%20-%20Haukur%20J%C3%B3hannesson%20og%20Kristj%C3%A1n%20S%C3%A6mundsson.pdf)

In approximately 6 million years Hallarmúli has drifted this distance, according to the measured drift vectors

Hallarmúli is measured to be about 6 million years old, and with the velocity of close to 2 cm a year, it should have drifted this far away from Hekla. It is also in accordance with the direction of the vectors.

This is a proof that the drift vectors, measured with GPS technology in 2004 compared with 1993 point locations, show real drift direction and speed. Actually, the proof is double, because a fault zone is accompanied with the sites of Hekla and Hallarmúli as shown below:

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.
