Q of the Earth

Global, Regional, and Laboratory Studies

"Variations in seismic Q are sensitive to a much greater extent than are seismic velocity variations on factors such as temperature, fluid content, and the movement of solid state defects in the earth. For that reason an understanding of Q and its variation with position in the earth and with time should provide information on earth's tectonic evolution, as well as on aspects of its internal structure. Papers of this volume present new information on Q in the earth from several perspectives: methodology, results from global and regional observations of both body and surface waves, laboratory measurements, and theoretical understanding. The editors believe that the present volume reaches a new threshold in Q studies and that advances in data quality and methodology will spur increased interest in this difficult, but interesting field."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
