Abstract

By using the Pn vs. {Delta} curve found in Part I of this paper and by assuming the focal depth of one seism, the focal depths of the other seisms are found by comparing the amplitude of Pn and that of the surface waves. The depths found are reasonable and the scattering of the results is small.
