Map view of the distribution of the 100 focal mechanisms used in this study. The different color of the beach balls indicates the different sectors, blue—Peloponnese, green—Kithira-Western Crete, red—Crete, purple—Karpathos-Rhodos. For each sector we present lower hemisphere projections of the directions of the principal stress axes obtained from the datasets listed in Table 1 (see also text for more details). The square represents the σ1 axis, the circle signifies the σ3 and the triangle the σ2 axis. The colored dots define the 68% confidence region of each stress axis.
