Mantle Love Waves

Abstract

Using the variational calculus method developed in previous papers, we attack the mantle Love wave problem for the model earths by Jeffreys and Gutenberg. Contrary to the conclusion from the corresponding mantle Rayleigh wave problem, the Jeffreys model gives better agreement with observations of mantle Love waves than the Gutenberg model, in which there is a low velocity layer at a depth of about 150km.
