Summary
The zones of glacially induced faults in Finland are portrayed by a number of discrete <10 km-long fault scarps, often forming multiple parallel segments and establishing longer glacially induced fault systems. A set of glacially induced fault systems further form glacially induced fault complexes, which may extend tens of kilometres cross-cutting glacial sediments. The systematic mapping has revealed 18 glacially induced fault systems forming 9 glacially induced fault complexes. The moment magnitude estimates for the earthquakes in Finnish Lapland are in the range of Mw ≈ 4.9–7.5. The detailed trenching across fault scarps provides evidence of non-stationary seismicity and occurrence of multiple slip events even before the Late Weichselian maximum.
