Abstract
This paper presents a physico-mathematical model and an algorithm for generating microseismic activity during hydraulic fracture propagation. Defects (inhomogeneities) of the rock are described using the ESC-model. Formulas for displacements discontinuities and characteristics of seismic and aseismic events are obtained. The algorithm was implemented and tested in the program. Calculations for pseudo3D and planar3D models of fracture propagations are carried out. It was found that the field of microseismic events can approximately restore the evolution of a hydraulic fracture in time, what is consistent with observations.
