Source mechanism of the Alaskan earthquake of 1964 from amplitudes of free oscillations and surface waves — comments

Abstract

Recently Ben-Menahem et al. (1972) (hereafter abbreviated to B.R.I.) proposed, on the basis of long-period surface-wave and free-oscillation data, a steeply dipping fault model for the Alaskan earthquake of 1964. This result differs from that obtained by Kanamori (1970) (hereafter abbreviated to K.70) who also used long-period Love and Rayleigh waves, but preferred a low-angle fault model. I would like to make several comments on this difference.
