Abstract

Some years ago the author gave wave theories for the propagation of the above mentioned waves. But there the approximations were not completely justified and in the theory for G-waves the earth's model and the analysis were of a different kind from those used in the other theories. In the present notes, the theories have been modified to some extent and substantiated by graphical representations. In the cases of T-, Lg-, and Rg-waves the principal aim has been to demonstrate low period energy concentration. In the case of microseisms from storms over deep sea, this aspect has been examined to find whether they can be present while sub-oceanic Rayleigh waves are always absent. Lastly, developing a theory similar to the previous four cases, it has been shown that for G-waves there is practically no energy concentration due to the low velocity layer.
