Post-glacial fault scarps in Jämtland, central Sweden

Abstract Analysis of a light detection and ranging-derived digital elevation model has revealed previously unknown fault scarps in central Jämtland, Sweden. These are interpreted to have been formed by earthquakes at the time of deglaciation, c. 10 ka BP, in an area with current low-magnitude seismicity. The dating is based upon morphology and comparison with similar features at other locations in Sweden but not supported by independent dating. Observed scarps are 0.4–6 km long, 2–8 m high, trending SSW–NNE to WSW–ENE, the northern and western sides uplifted. The dimensions of the scarps suggest an approximate moment magnitude M 7 of the strongest corresponding earthquakes.
