An Application of the Coherent Noise Model for the Prediction of Aftershock Magnitude Time Series

Figure 4

How the sets of the successive extrema of aftershocks are formed in the case of the Landers EQ. In each rectangular box the aftershocks with are arranged vertically according to their order of occurrence. Each time a new aftershock (shown in italics) takes place, the members of (shown in bold) are obtained by discarding all the previous members, that is, those of , that are smaller than . The number of elements of is the cardinality denoted by .
