The research work on the topic of ‘‘Tomography of the Earth’s Crust: From Geophysical Sounding to Real-Time Monitoring’’ has focused on the development of cross-scale multiparameter methods and their technological application together with the development of innovative field techniques. Seismic wave field inversion theory, diffusion and potential methods were developed and optimized with respect to cost and benefit aspects. This volume summarizes the scientific results of nine interdisciplinary joint projects funded by the German Federal Ministry of Education and Research in the framework of the Research and Development Program GEOTECHNOLOGIEN. Highlights and innovations presented cover many length scales and involve targets ranging from applications in the laboratory, to ground water surveys of heterogeneous aquifer, geotechnical applications like tunnel excavation, coal mine and CO2 monitoring and the imaging and monitoring of tectonic and societally relevant objects as active faults and volcanoes. To study these objects, the authors use the full spectrum of geophysical methods (ultrasonics, seismic and seismology, electromagnetics, gravity, and airborne) in combination with new methods like seismic interferometry, diffuse wave field theory and full-wave-form inversion in 3D and partially also in 4D.

Developments in Geotectonics 8: The Structure of the Earth's Crust Based on Seismic Data covers the papers presented at an International Upper Mantle Committee (lUMC) symposium called ""Crustal Structure Based on Seismic Data"", held on July 30-31, 1971. The book focuses on the structure, composition, and characteristics of the earth's crust. The selection first offers information on the crustal structure of Central and Southeastern Europe by data of explosion seismology; structure of the earth's crust on the territory of the U.S.S.R.; and seismic studies of low-velocity layers and horizontal inhomogeneities within the crust and upper mantle on the territory of the U.S.S.R. The text also takes a look at the deep seismic investigations in the Baikal rift zone and crust of the arctic seas of Eurasia. Discussions focus on peculiarities of crustal structure, structure of the uppermost mantle, and method of investigation. The publication takes a look at the crustal structure of Japan as derived from explosion seismic data; crustal structure in the Matsushiro earthquake swarm area; and Soviet seismic studies of the earth's crust in the Pacific Ocean during the International Upper Mantle Project. The selection is a dependable source of information for readers interested in the structure of the earth's crust.
