Abstract: | Memory of a stochastic process implies its predictability, understood as a possibility to gain information on the future above
the random guess level. Here we search for memory in the mining-induced seismic process (MIS), that is, a process induced
or triggered by mining operations. Long memory is investigated by means of the Hurst rescaled range analysis, and the autocorrelation
function estimate is used to test for short memory. Both methods are complemented with result uncertainty analyses based on
different resampling techniques. The analyzed data comprise event series from Rudna copper mine in Poland. The studies show
that the interevent time and interevent distance processes have both long and short memory. MIS occurrences and locations
are internally interrelated. Internal relations among the sizes of MIS events are apparently weaker than those of other two
studied parameterizations and are limited to long term interactions. |
