Description / Table of Contents: Geodynamics concerns the dynamics of the earth's global motion, of the earth's interior motion and its interaction with surface features, together with the mechanical processes in the deformation and rupture of geological structures. Its final object is to determine the driving mechanism of these motions. It is highly interdisciplinary. In providing the basic geological, geophysical infromation required for a comprehensive mechanical analysis, there are also many mechanical problems involved, which means the problem is coupled intricately with geophysics, rock mechanics, seismology, structural geology, etc. This is Part II of the Proceedings of an IUTAM/IASPEI Symposium on Mechanics Problems in Geodynamics held in Beijing, September 1994. It discusses different aspects of mechanics problems in geodynamics involving the earth's rotation, tectonic analyses of various parts of the world, mineral physics and flow in the mantle, seismic source studies and wave propagation and application of the DDA method in tectonic analysis.

Description / Table of Contents: Induced seismic events are of high scientific and economic significance. They are the result of human activities interacting with regional and local tectonics, changing the local crustal stress state by mining, extraction of rock masses, injection of fluids into the rock massif, and by changing the surface loading and pore pressure state near large reservoirs. Within Europe the study of induced seismic events has a long tradition and international scientific organizations have actively stimulated the co-operation in this field. During its General Assembly in September 1994, the European Seismological Society organized the symposium "Induced Seismic Events". The focus of this symposium was concentrated on induced events in central and eastern Europe, as well as in the former Soviet Union. The major contributions to the symposium, and also some Chinese, Canadian, and South African results are presented here. Case studies as well as data analyses and methodological studies are included. Seismologists and specialists working in the field of geohazard prevention will find much information in this volume that is pertinent to their work.

Description / Table of Contents: The special issue contains contributions presented at the international workshop Seismic waves in laterally inhomo- geneous media IV, which was held at the Castle of Trest, Czech Republic, May 22-27, 1995. The workshop, which was attended by about 100 seismologists from more than 10 countries, was devoted mainly to the current state of theoretical and computational means of study of seismic wave propagation in complex structures. The special issue can be of interest for theoretical, global and explorational seismologists. The first part contains papers dealing with the study and the use of various methods of solving forward and inverse problems in complicated structures. Among other methods, discrete-wave number method, the finite-difference method, the edge-wave supperposition method and the ray method are studied and used. Most papers contained in the second part are related to the ray method. The most important topics are two-point ray tracing, grid calculations of travel times and amplitudes and seismic wave propagation in anisotropic media.
