von Seggern, D; Blandford, R

Problems in accurate determination of seismic threshold magnitude are analytically tractable for only some simple, but interesting, cases. The report gives these analytic results and proceeds to a simulation experiment to provide insights where analytic predictions are not possible. Differences in direct, incremental, and cumulative threshold determinations; distinctions between true and observed thresholds; effects of correlated signals and noise; feedback between LR and P thresholds; and estimation of (M sub s)-(m sub b) relationships are treated in this simulation experiment. A comparison of simulated detection results is made with real data from LASA on the Kamchatka-Kurile region and good agreement is obtained between predictions and observations.
