Seismotectonics and Lithospheric Stresses in the Northern
The seismicity, fault distribution and stress pattern of northern Fennoscandia are investigated. Some active fault zones are suggested, e.g., several faults exposed to large displacement at the late-glacial phase about 9,000 years ago. Stress orientations, derived from crack distribution and a few e...

| Summary: | The seismicity, fault distribution and stress pattern of northern Fennoscandia are investigated. Some active fault zones are suggested, e.g., several faults exposed to large displacement at the late-glacial phase about 9,000 years ago. Stress orientations, derived from crack distribution and a few earthquake focal-mechanism solutions, are different in different areas. In some cases there is a good agreement with expectations from ridge-push generated and propagated compressive stress. However, the inhomogeneity in the stress field of the region as a whole indicates contribution from local factors. |
