Essay

The thesis is devoted to the determining of focal mechanisms of earthquakes based on kinematic and dynamic approaches. The kinematic approach consists in using of a graphic method. The difficulties are analyzed of using the method for determination of mechanisms of small earthquakes in different seismically active regions. The dynamic approach consists in inversion of waveforms of first arrivals of P-waves for components of seismic moment tensor. A method developed in the thesis for the inversion of waveforms is supplemented with a procedure for transformation of coordinates enabling a determination of mechanism based on a small number of stations. A method also is proposed for the determination of parameters of extended source. Based on the methods developed in the thesis applied programs have been designed and tested using the synthetic and real data.
