The Clear Picture of Tectonic Drift

With GPS technology, we finally could measure tectonic drift quite accurately. Iceland is divided into two parts, and it is manifested with direct measurement. The points measured have been fixed, the satellites give signals to relevant equipment. After measuring the points twice, the vector of displacement appears clearly. This is the result:

The tectonic drift of Iceland.

This can be manifested from the report:, and also

Both reports make it clear that these vectors are the results of measurement. All other vectors are found by changing their directions and length according to a formula. Therefore, we should adhere as much as possible to this original result of measuring the tectonic drift, to remain closer to the truth, being able to know about reality, and be aware of the facts we should base our understanding of the world on.


The Central Role of S-America within Tectonic Drift Patterns

Looking at the equatorial pattern of distribution between land and ocean, the regularity level is almost perfect. Land occupies 30° for S-America, Africa and Indonesia, Ocean spans 60° for Atlantic Ocean and Indian Ocean. The Pacific spans 150°. This perfect distribution can be compared with the theoretical 1:1 mantle convection height to width ratio:

S-American dilemma of equator.

The accurate distribution of land masses, and how it fits to the 1:1 ratio of mantle convection compared with Earth’s layers is very convincing. Then we suddenly realize that tectonic drift must lead to rearrangement of this. But it does not mean we have to run away from this finding, hiding somewhere. That would be silly. Stop for a moment and look at the very special position of S-America, with a regularly shaped trench at one side, and the estuary of the largest river in the world at the other side, 30° apart. These settings are more developed than for Africa, with the coast located 60° east of Amazon Estuary, and the Great Rift Valley found 30° east of the western coast. One idea is that S-America has remained over the same convection roll since the time of Pangea, and Africa has moved eastwards as the Atlantic Ocean developed in between. The situation now is that the wideness of the Atlantic along equator tends to prevail as 60°. One has to study the tectonic drift vectors to realize how that happens.


The Circle of Amazon

The pattern of land distribution along equador is one of the characteristics making our globe beautiful seen from space. Pointing the regularity out makes us think as well as feel. This circle spanning 30° along along 0° of latitude tells a story. A string is drawn through the circle, showing how the Amazon area is approximately aligned.

The circle of Amazon.

The forces of tectonic drift have been affecting South America quite strongly. According to the model of convection rolls, the Amazon estuary is located at a divisional line/point of downwelling between two large scale convection rolls of lower mantle. The span of the continent is exactly 30° along equator from coast to coast. This provides some constrains on the tectonic drift, causing South America to rotate. This circle represents one aspect of these present movements.


The Aleutean Islands Arc

The Aleutean Islands form an arc as the Pacific Plate drifts underneath the North American Plate. It is tempting to study a bit closer, because it seems like a semi-circle with a string from east to west. Let us follow the islands, connecting them with a line, and see what we get:

The area of Kamchatka is geologically extremely important, becauase in those areas the North American Tectonic Plate meets the Eaurasian Plate. A main division line of the model used here does cross the peninsulas there.

Geothermal Resources and Mantle Convection at the World Geothermal Congress in Reykjavik 2020+1

To introduce the model of convection rolls and how it explains the existence and distribution of geothermal resources in Iceland, I take part in the World Geothermal Congress held in Reykjavik this year (2021). The model should better have been developed in the nineteenth century when it was realized that land mass is regularly distributed along equator, and that must be for a reason. Someone should have considered that the span of the Atlantic Ocean and the Indian Ocean of 60° represented two large convecction cells, and the mainland of S-America, Africa and Indonesia span 30°, did show the location of a single large scale convection cell underneath. But no one did, so this became a debate finding place within the twentyfirst century! Harry Hess was on the correct track in 1962 with the article ´History of Ocean Basins´. Further development effort by the scientific community of his theory would have made this website obsolete. But my video about geothermal resources is found here, meant to bring us all one step closer to the ‘correct track’ again:

The abstract is found on the website of WGC:

Realizing that convection takes place within the mantle is easy and acknowledged by virtually everyone engaged in geoscience. The convection pattern, on the other hand, was a bit hard to derive. Now it has all been clarified and shown to everyone. The starting point is obvious enough to be 100% convincing, namely the fact that convection rolls with height to width ration 1:1 clearly fit exactly within the equatorial plane. The rest has to be found out, step by step, with the help of some knowledge about physics. You have to consider that the Earth rotates, that the mantle convects, and the constraints resulting from the geoid shape. Then you find out the exact dimensions, shape and location of the convection rolls within the Earth.
