Stress tensor inversion and fault plane solution results for the Çınarcık cluster. Equal area projection of the number of misfit polarities used to define the orientation of the principal stress axes is shown: (a) the distribution for the maximum compressive stress axis, σ1, (b) the distribution for the intermediate compressive stress axis, σ2, (c) the distribution for the minimum compressive stress axis, σ3, (d) lower hemisphere projection of the P- and T-axes of the focal mechanisms determined simultaneously with the stress tensor parameters, (e) the number of misfit polarities versus stress magnitude ratio, R. The numbers above the legend indicate the numbers of aftershocks and the total numbers of polarities used in the inversion.
