Surface-wave observations after integrating active and passive source data

摘要: Empirical Green's function (EGF) retrieval and turning ambient noise into useful signal by crosscorrelation or seismic interferometry (Curtis et al., 2006) has been a popular topic in recent years the seismological community. Many have discussed how interstation distance its equivalent affects accuracy of that can be retrieved long-range between two stations (e.g., Snieder, 2004; Bensen 2007; Halliday Curtis, 2008; Tsai, 2009; Kimman Trampert, 2010). It is generally accepted necessary optimum strongly depends on source distribution, length records (and, hence, naturally related to distribution), duration retrieved. Noise generated surface efficiently used reconstruct waves if we focus phase, not too concerned with amplitude Green's...
