What is the volcanic belt?

volcanic belt is a geographical area in which very high levels of volcanic activity are present. They are often compared with mountain belts, but unlike mountain belts, volcanic belts are able to produce eruptions of gases, ash, rock, lava or other eject. In addition, some volcanic belts have been so many years that they have been eroded almost flat. They can form in two different ways: subduction of the board or because of hot places on the ground. This melted material, called magma, becomes less dense than a rock, because atomic level causes heat, atoms have become more excited and vibrant in a larger area of ​​space. Materials that are less dense always try to climb, so the magma rises and is looking for any weak space in the Earth's crust. The result is usually a bulge in the country a circle, which eventually opens if the pressure becomes sufficiently large. The volcanic belt is simply many of these bulges in the area.

4 These plates move on the layer of mixable rocks called athenosphere. Geologists think that this movement occurs at least partly due to convection currents that are deeper on Earth. At the boundary of the subduction plate, where one plate slips below another, the melting of the bark material becomes at a higher speed, so the boundaries of the subduction plates are often a place where volcanic strips are formed.

Sometimes a volcanic belt is formed because the tectonic board moves slowly across the area where the inner ground is much warmer than usual. In this case, the volcanic belt can occur far from the boundary of the album. Perhaps the best example of a volcanic belt created in this way is the Hawaiian Islands.

Volci

​​may take hundreds or even thousands of years between eruptions, depending on the speed that the material melts under the bark and how quickly the pressure is. As a result, many volcanoes inside the volcanic strips are sleeping. This does not mean that they will not explode in the future. It just means that in the present dayThe times are not active. Geologists use more and more sophisticated technologies to try to anticipate when eruptions will occur, but people still build and live in close proximity to volcanic belts despite danger. Subsequently, there is still the potential of loss of property and life due to eruption.
