The consortium research project Seismic waves in complex 3-D structures (SW3D), started October 1, 1993. It focuses primarily on the fundamental issues of high-frequency seismic wave propagation in complex 3-D isotropic and anisotropic structures, which go beyond the traditional approaches. The ray method and its extensions, as well as its combination with other methods are mainly applied and investigated. The emphasis is put on new, stable, more efficient and flexible algorithms for both forward numerical modelling and inversion of seismic wave fields in 3-D inhomogeneous, isotropic and anisotropic structures. Considerable attention is also devoted to applications involving S waves, converted waves, S-wave splitting and coupling in anisotropic media, particle ground motions, etc.
The principal investigators of SW3D are Vlastislav Cerveny (project leader), Ludek Klimes and Ivan Psencik. Graduate and postgraduate students of the Department of Geophysics, Faculty of Mathematics and Physics, Charles University, also participate in the project.
The project is supported by a consortium which members are oil companies and universities.
Once a year a meeting with sponsors is organized during which the sponsors are provided by the research reports and computer codes developped during the period since the previous meeting.
Yearly fee for industry: 16 000 EUR (all taxes included).
Yearly fee for small companies: 8 000 EUR (all taxes included).
