New approach to physics of earthquakes and volcanoes

The author in recent years is developing a shock-wave model of the earthquake. The shock wave (SW) at the time of the earthquake is formed when the structural phase transition is realized in the hypocentre region, it comes to the surface of the Earth and is reflected. In this case, a reflected wave of expansion (discharge) appears, directed opposite to the shock wave. The interaction of these waves leads to strong movements: surface ruptures, decompaction of the ground, its vibrational movements, and so on. It is known that earthquakes and volcanic eruptions are «related phenomena». They occur on Earth, as a rule, in the same place (for example, on the coast of the Pacific Ocean). Analyzing the seismic wave pattern under the source of volcanoes, one can see that in most cases the magmatic source does not have roots that go into the mantle to the outer core of the Earth. The question arises, how is an magma chamber isolated from the outside world created, and how does magma preheat it? As you know, there is no sound answer. In this work, a fundamentally new model of the volcano is proposed, according to which the origin of the magma chamber and its regular «feeding»by energy occur due to shock waves exactly the same as those that cause earthquakes. The shock wave, which leads to an earthquake, spreads in an elastic medium and comes to the Earth’s surface with practically no loss of energy and when it leaves the earth’s surface it destroys it. If the hydrocarbon meets in its path an inelastic (eg porous or liquid) medium in which an unloading wave occurs, then the shock wave dissipates with heating of the medium and the formation of a magmatic source. It is obvious that on the surface of the Earth in this case the SW leaves a completely different «trace and this will already be a volcano.
