- W2007668703 abstract "A skew, approximately log normal, P amplitude distribution across the Norwegian Seismic Array (Norsar) results in a positive bias in its event magnitude estimates. This effect is on the average zeroed out owing to a negative bias caused by signal energy losses during the array beam-forming process. A comparison between Norsar and NOAA magnitudes shows that the difference is largest at mb ∼4.7 and then tapers off toward both small and large event magnitudes. For NOAA magnitude values less than 4.0, Norsar reports relatively large mb values. A multivariate analysis of International Seismological Centre (ISC) data for Japan and the Aleutian Islands gave a consistent and linear relationship between the ISC event magnitude and that predicted from subsets of five to nine stations in the mb ∼ 4.0–6.0 magnitude range investigated. In this respect the ISC-reported magnitudes are considered unbiased. We also found that the magnitude observations can be approximated by a normal distribution. In many cases the so-called magnitude station correction term was not a constant but a function of event magnitude; i.e., a linear model is recommended for describing the magnitude relationship between individual stations and NOAA, ISC, or ‘true’ event magnitude. This phenomenon is quantitatively explained as the combined effects of the seismic spectra scaling law (Aki, 1967, 1972) and the frequency-dependent crust-upper mantle transfer function." @default.
