Diagrams showing the stability of the CMT inversion of the 2014 Aegean Sea earthquake. a Obtained focal mechanism and variations of the nodal planes obtained at locations surrounding the best-fitting source centroid. Those obtained at the eight surrounding grids (0.1° difference) in the horizontal directions next to the best-fit location are plotted together with the best-fit solution. b Focal mechanism obtained by the GlobalCMT project, plotted with the nodal planes of best double-couple. c, d The residual distributions with respect to the directions of the T- and P-axes, respectively, plotted on the focal sphere at the best-fit source location. The filled and open triangles indicate the direction of the best-fitting T- and P-axes
