Correlation between characteristic parameters of aftershock distributions in time, space and magnitude

Aftershock sequences which occurred in Japan from 1971 through 1993 are investigated by fitting the modified Omori formula and the Gutenberg-Richter relation to find that p- and b-values have a positive correlation. It is also shown that there are positive correlations between each of these parameters and the fractal dimension of hypocenter distribution of aftershocks.
