Fluids have a significant impact on seismic processes in the lithosphere and the earth's crust. They can form systems of mantle-crust migrants that rise in a solid plastic medium due to fluid-fracturing. When migrants are formed, the energy accumulated earlier in the parent chambers under the strength barriers is released. The accumulating energy includes the potential energy of lithostatic pressure 𝑊𝑃 and the energy of deformation of the strength barrier 𝑊𝐸. The released energy includes the energy of cavity formation 𝑊𝐶 in the strength layer and the energy of fluid ascent into the cavity 𝑊𝐹. According to the condition 𝑊𝑃 + 𝑊𝐸 − 𝑊𝐶 − 𝑊𝐹 > 0, the remaining mechanical energy is the cause of such seismic events as rock bursts, unstable zones of low longitudinal wave velocities and seismic “nails”.
