"Automatic reconstruction of fault networks from seismicity catalogs: Three-dimensional optimal anisotropic dynamic clustering"^^ . "We propose a new pattern recognition method that is able to reconstruct the three-\ndimensional structure of the active part of a fault network using the spatial location of\nearthquakes. The method is a generalization of the so-called dynamic clustering (or k\nmeans) method, that partitions a set of data points into clusters, using a global\nminimization criterion of the variance of the hypocenters locations about their center of\nmass. The new method improves on the original k means method by taking into account\nthe full spatial covariance tensor of each cluster in order to partition the data set into fault-\nlike, anisotropic clusters. Given a catalog of seismic events, the output is the optimal set of\nplane segments that fits the spatial structure of the data. Each plane segment is fully\ncharacterized by its location, size, and orientation. The main tunable parameter is the\naccuracy of the earthquake locations, which fixes the resolution, i.e., the residual variance\nof the fit. The resolution determines the number of fault segments needed to describe the\nearthquake catalog: the better the resolution, the finer the structure of the reconstructed\nfault segments. The algorithm successfully reconstructs the fault segments of synthetic\nearthquake catalogs. Applied to the real catalog constituted of a subset of the aftershock\nsequence of the 28 June 1992 Landers earthquake in southern California, the reconstructed\nplane segments fully agree with faults already known on geological maps or with blind\nfaults that appear quite obvious in longer-term catalogs. Future improvements of the\nmethod are discussed, as well as its potential use in the multiscale study of the inner\nstructure of fault zones."^^ . "2008-01-17" . . "113" . "B1" . .
