read ABSTRACT.
Microprocesses occur like chain rcact ions where bonds progressively yicld. The tempora! evolut ion can be tracked by multifrequcncy AE . Two principle ideas. Onc rclies on time series of A E of increasingly lower frequency.Thc sccond compares time histories of cvcry AE event (fix.ed frequency) with a lognormal distribution: dcviations revcal additional paramcters, and the tail results modulated by cxtemal effccts, cnvisaging what triggers evcry AE . Natural environmental phcnomcna are effcctive feasibility tests, for subsequent laboratory implementati on.
