The earthquake in the territory of Kamchatka once again attracted public attention to natural disasters, and nowhere they happen often as on the Pacific fire ring. Livescience.com information portal speak About this geological monument explained why it is very important to science.
The Pacific volcanic fire is a huge belt of active volcano and sleeps around most Pacific Oceans. It goes from the southern part of Chile along the western coast of the United States, through the islands of Alaska and Down, through Japan, to the Philippines. Some geologists also include an Indonesian volcano chain in this belt.
These volcanoes appear as a result of sinking: A geological phenomenon in which an assist is under the other, reducing the melting point of rocks in the coating. As a result, it turned into Magma, appearing on the surface and broke out in a volcanic form.
The peculiarity of the fiery ring is the extra production that occurs on a huge scale, because it is in the Pacific Ocean, the boundary of some ocean plates placed. For the context, about 90% of 55,000 km of sinking boundaries of the plates on Earth are in the Pacific Ocean.
The creation movement also causes earthquakes. When one sheet is under another, they rubbed together, leading to the largest seismic events on the planet. In addition, within the fire, about 75% of all volcanoes operate on earth.
It is noteworthy that the name Fire Fire Ring is the subject of disagreement in the scientific environment. Many scientists cannot stand. First, because the circle is not really a ring. The volcanoes are located along the boundaries of tectonic plates, and the sinking only occurs in the north, east and western Pacific. And in some parts of the belt, in principle, there is no volcano – for example, in Peru and the center of Chile.
In addition, the fire ring has more than 450 volcanoes in different areas. They are not the same in the production of Magma, storage and positioning of the sinking plate. Each volcano has its own history, from the viewpoint of science, and is more concerned than part of the ring. They have no meaning to connect with each other.
Some experts also believe that this term has had the wrong importance in public culture. Because it, many people think that fire ring is a unique structure, while this term is simply invented for convenience. It exists because there are many volcanoes along the edges of the Pacific Ocean. Such Viking's ring ring is nothing more than a coincidence of geography. And no, an eruption in which does not threaten to release a string reaction, because, once again, the volcanoes are not really linked together. The eruption of volcanoes in Japan will not lead to eruption in Chile.
Studies on the Pacific volcano ring include many spheres. About two -thirds of volcanoes have broken out on the ground since the 1960s there, so the Pacific region was called the “natural laboratory” of volcanoes, especially exploding. Volcanic houses can use data collected in the round to study various eruptions. In the future, this will help talk a lot about the internal mechanisms of volcanoes operating at a depth of many kilometers underwater.
