Abstract : This paper presents a study of the P and S waves in 37 different earthquakes. It shows that in the eastern part of China, there are marked regional differences in the characteristics of these waves. These differences could depend directly on the structural differences in the earth's mantle. The paper proves that there are low-velocity layers in the mantle and shows that there are regional differences in the characteristics of these layers. It also discusses the possibility of the existence of two surfaces of discontinuity in the mantle. (Author)
