Causes of building collapse remain unknown. The absence a clear answer about the causes of deformations of buildings and structures have long pay attention to many experts. Typically, this circle includes mining engineers Profile, surveyors and Geophysics – the people who worked on the underground mines and quarries and familiar with the concepts of the stress state of the geological environment. Most of them are inclined to think that an emergency condition of many engineering structures is caused by a wrong approach for the Engineering Research and underreporting of modern geodynamic activity of the geological environment. Until recently, geologists believe that the earth's crust, except in areas of active volcanism and manifestations seismic events (dangerous in terms of earthquakes) is at rest, ie immobile. However, at this stage with the commissioning of new measuring techniques, the use of satellite geodesy and development geophysical methods of investigation, it became apparent that the Earth's crust is constantly in motion. Roughly speaking, the earth goes right under our feet.

Displacement of the earth's surface and massive rocks have negligible amplitude and not visible to the eye but can have a significant impact, both on the rock mass, and on engineering structures. The mobility of the rock mass is related to their stress-strain state. In the Earth's crust is constantly affected by the forces (gravity, generating a voltage on the weight of rocks and tectonic forces), resulting in geological environment is always in a state of stress. Because the rocks always overstretched, they begin to deform and collapse.
