In the process of the propagation of deformation waves resonant phenomena occur in the block-layered massif. Studies of the rocks in a volumetric field of compressive stresses in the laboratory have shown that they are classical auxetics, in which elastic parameters vary abruptly within the limits of ± infinity. The transition of the modulus of the elasticity through the infinity is the condition of the resonance and the growth of a deformation increment, which is accompanied by the current. Adequation of a shear modulus and volume compression leads to a shock wave generating and a dynamic fracture. Resonant growth of maximum and minimum deformations is accepted as the precursor of the fracture, the concept of rocsk fracture as a local structural-phase transition is developed, on the basis of which the method for the prediction of geodynamic phenomena by deformation indices is created.
