Comparison of Regional Attenuation in Europe and in the United States

Abstract

A maximum likelihood estimation procedure was applied to observations of short-period P and S waves from deep earthquakes in Europe and in the United States in order to estimate regional variations in attenuation in the two regions. The separation is much less pronounced in Europe, indicating that the variability of the observations is much less than in the United States. The results indicate that attenuation effects under stations in Europe are not as important as in the United States and therefore that station magnitude biases due to attenuation are not likely to be significant.
