Distribution of phase tensor ellipses for periods of 1 s (upper panel), 31 s (middle panel) and 182 s (lower panel). The left, center, and right diagrams of each panel show the observed data, synthetic data of the final model, and synthetic data of test model 1, respectively. The colors of the ellipses represent the value of the geometric mean (Ф2) of the maximum and minimum phase tensor. The color scale for topography is as in Fig. 1
