"A pattern recognition algorithm is developed to provide potential improvements over \nexisting earthquake prediction practices. The parameters employed in the analysis include degree \nof spatial nonrandomness in two distance ranges, spatial correlation dimension, spatial \nrepetitiveness of earthquakes with a similar size, average depth of events, time interval for the \noccurrence of a constant number of events, and ratio of the numbers of events in two magnitude \nintervals. The parameter temporal variations are compared quantitatively with the time series of \nlarge events using a technique of association in time. The significance of the association \nfrequencies is evaluated by comparison with chance associations estimated from corresponding \nsimulated random time series. The developed techniques differ from existing approaches in the \nfollowing aspects. The parameters here emphasize the spatial distribution of earthquakes. Possible \ncorrelations among the parameters are evaluated to determine the final set of parameters to be \nmonitored. Threshold values for the assumed anomalies are chosen with consideration of \nproperties of the available earthquake catalogs, such as the number of large events to be \nretrospectively predicted. Equal weight is given to both locally high and locally low parameter \nvalues. Care is taken to distinguish between anomalies preceding large events and those following \nprevious events. It is shown that the relationship between precursory local extrema and precursory \ntrends is nonunique, with precursory local extrema of the same type frequently associated with \nopposite observable precursory trends. The application of the seismicity parameters and pattern \nrecognition techniques is demonstrated using synthetic earthquake catalogs generated by models \nof segmented fault systems in a three-dimensional elastic solid [Ben-Zion, 1996]."^^ .
