The spatial and tlie time distribution of the aftershocks
of the earthquake of July 1968 in Epidavros (Greece) has been studied.
It was found that the value of b in Gutenberg-Richter's relationship was
nearly the same for the primary as well as the secondary or second order
aftershocks of the sequence. The focal mechanism of the second order
aftershocks as observed from the sense of first motion of P-waves showed
some difference from that of the main shock or its primary aftershock
of the earthquake of July 1968 in Epidavros (Greece) has been studied.
