Body Wave Magnitude and Source Mechanism

Abstract

A new method is proposed for improving the body-wave magnitude determination by using the observed values of the body-wave magnitude (m sub b) together with the first motion directions, to obtain by least squares analysis the best double couple source parameters; the resulting radiation pattern is then integrated spatially to provide a corrected estimate of the magnitude. Results for a number of events previously studied by other investigators are presented. (Author)
