PHYSICAL MODELING OF SEISMIC PROCESSES AT THE LABORATORY CONDITIONS

The experiments on sample destructions were conducted at the conditions of elevating relative deformational speed for ??~10??÷10?? s??, aiming to study general seismic regime qualitative regularities. Some major statistical regularities at deformation regime coincide with ones observing at seismic regime. Low speed pressing of the sample for e~10-9 s-1 at the rapture limit showed deformational anomalies similar to Earth crust deformations preceding earthquakes. The laboratory experiments showed the phenomenon of step like materials’ plastic deformations both in crystal and amorphous mediums stipulated by mechanical vibrations of a different frequencies spreading through the space environments.
