We present reprocessed data from seven profiles from the Forsmark site, the location where Sweden will store its spent nuclear fuel. The reprocessed data show improved images of the crust below 1 km since lower frequencies were preserved in the new processing sequences. These sections together with data from a longer more regional profile to the south of the area indicate that there may be a previously unidentified larger southwesterly dipping deformation or fracture zone in the southern part of the Forsmark area, well away from the planned repository.
