Abstract (EDOC: 6845)
The seismicity, fault distribution and stress pattern of northern Fennoscandia are investigated. Some active fault zones are suggested, eg several faults exposed to large displacement at the late-glacial phase about 9000 yr 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. Hoever, the inhomogeneity in the stress field of the region as a whole indicates contribution from local factors.
