The seismic activity in the area of Greece between 1966 and 1969

Abstract

The earthquake activity in the area of Greece for the
years 1966, 1967, 1968 and 1969 is investigated. This earthquake activity
as a rule follows the general pattern found by the use of data for a much
longer period. There is a clear tendency for the focal depth of the earthquakes
to increase from the convex side of the Aegean arc to the inner volcanic
arc.
The value of the constant b of the recurrence curves is much smaller
for the intermediate earthquakes than for the shallow ones.
