The lithospheric-ionospheric interaction and the complex of accompanying anomalous physical phenomena caused by critical geodeformations and electrification of rocks are considered as precursors of earthquakes based on the criticality theory. It is shown that scaling of dislocation changes in critical geodeformations, which can be represented as a transition to a turbulent state of coseismic rheological flows, is responsible for the anomalous properties of physical phenomena. The resulting instability of physical processes provides a high energy of anomalous phenomena, contributing to their detection as precursors of earthquakes.
