Earthquakes are common geological phenomenon on planet Earth. Depending on the magnitude, depth (focus) and area of occurrence (epicenter) are also responsible for natural disasters that involve intense destruction of buildings and unfortunately the loss of human lives.
It is recognized that there are difficulties in making predictions about when and where an earthquake of great magnitude could occur. Could this be due to the fact that there are many studies on the consequences and not about the real causes of earthquakes?
The seismological studies are conducted after the occurrence of an earthquake and, in this case, there is no way to make any predictions, because it would have been released seismic energy - the bullet had been triggered - and therefore only remains to study the behavior of seismic energy as his intensity, geometry, among others.
Very little is studied about the real causes of earthquakes. There is a geological paradigm that tries to explain that earthquakes are accumulated tensions related to fault lines or boundaries of tectonic plates that move. In fact, it would make sense, however because this would occur? What are the causes that influence fault movements? It is noteworthy that there are several areas on the planet with earthquakes positioned in intra-plate situation, not just at the boundaries of these plates. Another situation is try explain explain earthquakes related to conventional subdcution zone as postulated by Plate Tectonics that earthquake sources get deeper under the overriding tectonic plate proceeding away from the trench at a subduction zone, and would delineating the so-called Wadati-Benioff Zone. Some realize that these earthquakes would be formed by friction between plate slabs. Nevertheless, deep gas migration due buckling of continental border also offer an explanation, including associated magmatism also related to decompression due deep faults that form by buckling of shallow crust.

In summary it is essential to combine studies of the physical properties of the seismic energy with the chemical properties of earthquakes, i.e. the chemistry of earthquakes, this last one as a possible cause and the first as a consequence of the phenomenon.
