    Abstract:

    This paper introduces a method calculating the relative fractal factor and has calculated the relative fractal factors(D2)of after-shock sequences of the Leipo earthquake(Ms=5.4), two Kangding earthquakes(Ms=5.2, 5.8)and the Dayi earthquake(Ms=6(1)/(4)), using this method. The D2 factors, for above mentioned four earthquakes, are 2.26982, 1.93915, 2.28738 and 1.5367 respectively. Relative coefficient and related departure of every D2 are calculated and given. The D2 factor of aftershock sequence in which the strong aftershock occurred is larger than that of aftershock sequence in which the strong aftershock did not occur.
