Describing The Ring of Fire according to the map below, the San Andreas Fault and Yellowstone play the main roles. Accordingly, The Ring of Fire covers a rather wide area, mathematically confined. The San Andreas Fault has a section moving continually, as no pressure accumulates due to the fact that the drift direction of the Pacific Ocean Tectonic Plate is exactly parallel to the fault alignment. Just to add one fact, the sliding effect is due to the fact that the Pacific Plate drifts slightly away from the North American Plate at that point, but the North American Plate moves towards the point, so the combined result is a smooth, perpendicular meeting point. This is the most important thing to understand in an attempt to understand the preconditions of the Ring of Fire.

Yellowstone is therefore also a key point of the Ring of Fire. For a manifistation of that statement, we should have a look at a basic geological map of the Yellowstone Caldera:

Calderas tend to be regular, and therefore an elliptical form is used to aproximate the outlines of Yellowstone. Then the major and minor axis of the ellipse become apparent, and they are perpendicular and parallel, respectively, to the edge of the Ring of Fire at that location. The minor is aligned in the same way as San Andreas Fault. It is not necessary to add a detailed map of San Andreas Fault complex here, because everyone knows that it is logically parallel to the Ring of Fire.

Taking this a bit further, the Pacific Tectonic Plate drifts as a whole in one direction. On the contrary, the adjacent plates of America and Eurasia rotate towards the Pacific. The Ring of Fire also includes other plates than the Pacific Ocean Tectonic Plate, as it is defined. Other factors determine its scope too, and there we have the pattern shaped by convection rolls. The different layers of rolls have intersection points, coinciding with the outer and inner edges of the Ring of Fire. That provides the mathematical base for the elliptical form of the Ring of Fire. The way to realize this is simply to trace the two concentric yellow ellipses marking the Ring of Fire, and see how many intersection points each of them coincide with. The width of the Ring of Fire therefore always remains mathematically the same in proportion with the grid formed by latitudes and longitudes.

This description of the Ring of Fire is presently of a secondary nature, because first you have to have knowledge about the Mantle Convection Rolls Model, and then about the Ring and Fire and how it is related to the said model. Besides that, the tectonic drift vectors are not always presented as on the map above. A solid reference frame, and a view from space with GPS should describe tectonic drift in the best way. And it should be noticed that Yellowstone, according to this analysis, is a part of the Ring of Fire.

Geology can be difficult to comprehend, and there are many examples of misunderstanding the basic principles behind the processes gradually changing our planet. It is generally acknowledged that we still have a scientific frontier when it comes to tectonic drift, explaining location of volcanoes, geothermal areas and seismic zones. Here, an attempt is made to solve the problem and explain many of the remaining questions by analyzing the currents within the mantle. A few things are generally known, because they can be measured with confidence. That includes the thickness of layers, or depth of discontinuities, and the chemical properties of the mantle. We also know that the thermal gradient is adiabatic below 120 km depth. It is found that above 120 km the mantle does not flow, no convection takes place there. On the contrary, below 120 km convection does take place. As the thermal gradient is adiabatic, the mantle material is always on the verge of becoming stagnant. These conditions can be imitated in laboratories, and it is then discovered that the convection leads to formation of convection rolls, with the same height and width. This can be used to make a model of convection rolls within the Earth. The rotation of the Earth must be considered, but there are ways to do that according to physics, and thereby the location of convection rolls can be found. After doing this, surface features can be compared to the modelled convection rolls, and it turns out that everything fits. All over the world, volcanoes, geothermal sites, seismic zones, subduction zones and other features can be readily explained. This means that in the future, utilization of various resources will become much more systematic than today. This will improve our understanding of tectonics and the basic forces leading to tectonic drift. And it is easy in a way, because the convection rolls have been located very accurately. The different layers affect each other, and the surface, often in ways that makes it difficult at first to see the relationship between cause and effect. But with the comprehensive version of the model at hand, the role of each layer can be studied. With the three papers already published, examples about mid-ocean ridges, subduction, volcanic zones and seismic areas have been provided. Just take the time to learn what our planet is like. Icelandic geology made it possible to start this job, because Iceland is like a natural laboratory. Global aspect is also important, though, and by combining knowledge about the Earth in general and Iceland in particular, the publication of these papers could be realized.
