The source dynamic parameters of 12 earthquakes in Crimea with energy classes КП=7.0–10.1 have been restored by 63 amplitude spectra of P and S body waves registered by a group of regional seismic stations of the Crimea. For the three strongest earthquakes: May 1, October 15, and December 9, the solution of the focal mechanism has been obtained and the direction of radiation from the source at the registration station has been determined to take into account in the calculation of the scalar seismic moment. For these earthquakes, the best convergence of station definitions of all source dynamic parameters has been obtained. The average values of seismic moments and radii of circular dislocation within the experimental error of their determination satisfy the average long-term dependencies of the parameters on the energy level of earthquakes ob-tained previously by analog records
