Seismic reflection multi-stacked (MSF) data can be used in an urban environment for imaging the subsurface, since MSF data are not plagued by noise from an active city. The MSF method consists of a source and receiver, akin to a spot or jump correlation survey common in the 1930’s. Walk-away tests document that ground roll is eliminated from the near-source receiver. Two MSF seismic reflection profiles from 2 active urban sites in the southwestern portion of the USA show excellent resolution.
