    • SVD enhanced seismic interferometry for traveltime estimates between microquakes 

      Melo, Gabriela; Malcolm, Alison E. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
      In general, Green’s functions obtained with seismic interferometry are only estimates of the true Green’s function, introducing uncertainties to the information recovered from them. However, there are still many cases in ...

    • Microquake seismic interferometry with SVD enhanced Green's function recovery 

      Melo, Gabriela; Malcolm, Alison E. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
      The conditions under which seismic interferometry (SI) leads to the exact Green’s function (GF) are rarely met in practice, resulting in errors in the recovered GF. To alleviate this problem, we employ additional information ...

    • Visibility Analysis using Reverse Time Wave Sensitivity for Time-Lapse Target-Oriented Imaging 

      Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael (Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
      Identifying the relationship between surface seismic data and a particular region in the earth, referred to as visibility analysis, is important because it facilitates the optimization of the quality and speed of the imaging ...
