Seismic Threshold Determination

Abstract

Problems in accurate determination of seismic threshold magnitude are analytically tractable for only some simple, but interesting, cases. This 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.
