The nature of the electrical activity of mesoscopic defects in Ih ice and the relationship of this activity with the kinetics of plastic deformation and fracture is discussed. The theoretical time dependences of the shear caused by active dislocation pile-ups are compared with the shapes of actual electromagnetic signals generated in different stages of the plastic deformation of Ih ice. Good agreement with the model of free expansion of a conservative dislocation pile-up and the model of nucleation and propagation of a slip band is established.
