The Seismic Wavefield

The two volumes which make up The Seismic Wavefield provide a comprehensive 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 provided a general introduction and a development of the theoretical background for seismic waves. This material is exploited in Volume II to look at the way in which observed seismograms relate to the propagation processes. Volume II discusses local and regional seismic events, global wave propagation, and the three-dimensional Earth. The combination of observation and theoretical development with a strong visual focus will greatly appeal to graduate students in seismology. The two volumes will also be valuable to researchers and professionals in academia and the petroleum industry.
