    In M.Sc. thesis the character of the seismic event occurrence process in natural seismicity and seismicity induced by mining works was studied. The investigations were conducted based on data from an active seismogenic area of Greece and on series of mining seismic events from a Polish copper mine. The null hypothesis, assuming that the process of seismic event occurrence was Poissonian was verified. Two parameters were used: the difference between the empirical cumulative distribution of interevent time and the expotential distribution D(t), and the Matsumura’s coefficient of randomness. The bootstrap resampling technique was used for calculating confidence intervals of these parameters.
