Abstract:
The analysis of crustal stresses is a prerequisite for a detailed investigation of intraplate tectonic processes. This study restricts to the interpretation of the directions of maximum horizontal stresses, both from earthquake fault plane solutions (direction of pressure axes) and sigma-1 axes of in situ stress-measurements. In the W part of Central Europe the well-known NNW-SSE-directed compressive stresses are dominant. But other directions characterize the region joining eastward in the forefield of the East European platform. Numerical model calculations were carried out to interpret the collected stress features. Therefore, the plane stress state of the investigated region was simulated by an elastic plate under prescribed boundary loading. The governing equilibrium equations have been solved by a finite element procedure.-Authors
