A method based on nonparametric statistics (hereafter called “median- based analysis of the segment slope,” mbass) is applied for the detection of change points in frequency magnitude distributions (fmds). The determination of the lowest magnitude for which the Gutenberg–Richter relation still applies is a key point for the computation of reliable b-values. The change-point detection method presented here is used to determine automatically this threshold magnitude (called m0 in this ing when fmds are analyzed by eye.
