This book provides a guide to understanding of seismograms for graduate students, researchers, professionals in academia and the petroleum industry.The Seismic Wavefield provides a guide to the understanding of seismograms in terms of physical propagation processes. The focus is on the observation of earthquakes and man-made sources on all scales, for both body waves and surface waves. Volume I begins with a survey of the structure of the Earth and the nature of seismic wave propagation and then provides a full development of the theoretical background. This comprehensive text will greatly appeal to graduate students in seismology, and to researchers and professionals in academia and the petroleum industry.The Seismic Wavefield provides a guide to the understanding of seismograms in terms of physical propagation processes.

This comprehensive text will greatly appeal to graduate students in seismology, and to researchers and professionals in academia and the petroleum industry.The Seismic Wavefield provides a guide to the understanding of seismograms in terms of physical propagation processes within the Earth. The focus is on the observation of earthquakes and man-made sources on all scales, for both body waves and surface waves. Volume I begins with a survey of the structure of the Earth and the nature of seismic wave propagation using examples of observed seismograms. The second part provides a full development of the theoretical background for seismic waves. Volume II (to be published later) will cover local and regional seismic events, global wave propagation, and the three-dimensional earth.Preface; 1. Introduction; Part I.
