Seismic Reflection Imaging in Urban Settings

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