WebAn extension of the empirical Green's function (EGF) method is presented that involves determination of source parameters using standard EGF deconvolution, followed by inversion for a common attenuation parameter for a set of colocated events. Recordings of three or more colocated events can thus be used to constrain a single path attenuation … Web1.1. Reconstruction of the Green’s Function From Correlations of Random Fields [2] The correlation of long time series of seismic ambient noise makes possible the empirical synthesis of the earth response (Green’s function) between the stations.
