Abstract
We apply the reciprocity method (EISNER and CLAYTON, 2001a) to compare the full waveform synthetic seismograms with a large number of observed seismograms. The reciprocity method used in the finite-difference modeling allows for the use of high quality data observed from the earthquakes distributed over the wide range of azimuths and depths. We have developed a methodology to facilitate the comparison between data and synthetics using a set of attributes to characterize the seismograms. These attributes are maximum amplitude, time delay and coda decay of the magnitude of the displacement vector. For the Southern California Velocity Model, Version 1 (MAGISTRALE et al., 1996), we have found misfits between data and synthetics for paths traveling outside of the sedimentary basins and the western part of the Los Angeles and San Fernando basins.
