Burträsk Fault (Swedish: Burträskförkastningen) is a large geological fault located in Northern Sweden. The fault had a major period of seismic activity following the deglaciation of Fennoscandia about 10,000 years ago.[1] On surface the fault can be observed in the form of a fault scarp, but the fault is longer than the scarp implies.[1] Likely extends northeast below sea level into the Bothnian Bay.[1] The Burträsk fault is one of several postglacial faults in northern Sweden that remain seismically active. Currently, it is the most seismically active area in the whole of Sweden. [2]
