Earthquakes from the point of view of mechanics of contact interaction of surfaces

Abstract

The work is devoted to earthquake forecasting. The physics of an earthquake, despite the fact that this problem has been facing humanity for more than 100 years, it still remains unclear. What is the reason and why this is a very important problem, which is being solved by a huge number of universities, institutes and companies around the world. The physical model of a tectonic earthquake is presented in the form of a plate connection loaded with a shear force, in which the non-displacement is provided by friction forces. In calculating the contact interaction, the pliability of the plates and the tangential pliability of the contact layer are taken into account. A system of equations has been obtained, the solution of which makes it possible to specify to some extent the location, strength and time of the earthquake occurrence.
