Inter-group distances and intra-group variance. (a) Heat map of distances between event centroids binned by magnitude M. (b) Heat map of distance between samples within groups binned by rupture distance \(R_{\textrm{rup}}\). (c) Box plots of intra-group standard deviation for each event, binned by M; total standard deviation indicates the standard deviation for all samples. (d) Heat map of geometric distortion in the distance between event centroids, binned by M. (e) Heat map geometric distortion in the distance between samples within groups binned by rupture distance \(R_{\textrm{rup}}\). (f) Scatter plot of geometric distortion in the average intra-group standard deviation for each event, binned by M; total geometric distortion indicates the distortion in the standard deviation for all samples.
