Abstract

Fault scarps, interpreted as post- or late-glacial in age, occur in northern Sweden and adjacent parts of Finland and Norway. In the Lansjärv area in northern Sweden, attempts have been made to date fault displacement relative to the glacial and postglacial stratigraphy by trenching across fault scarps. It is shown that the faulting occurred soon after the local deglaciation some 9000 years ago with no signs of movements since. The faulting appears to have been associated with violent earthquakes, because landslides and soil deformation, interpreted to be seismically induced and dating from the same period as the faulting, are frequently found in the area.
