The following PDFs are from the collection of R. B. Herrmann. The first set of papers by Lamb, Lapwood and Nakano were distributed by William Stauder suring a course on Elastic Wave Theory and Advanced Seismology. The Lamb and Lapwood papers discuss the nature of seismograms through contour integration. The Nakano theory discusses radiation patterns from various combinations of couples. This paper was the basis for the debate on single-couple and double-couple source machanisms, which was eventually resolved by studies on dislocation theory by Maruyama (1964) and Burridge and Knopoff (19XX).
The paper by Anatoli Levshin and Zena Yanson (1971) was translated by R. B. Herrmann in 1972 and formed the basis of his Ph.D. Dissertation.
