Determination of surface-wave phase velocities by zeros of Aki’s spectrum of active-source records: Application to the dense array in Tongzhou, ChinaKey points

The spatial autocorrelation (SPAC) (also known as the Aki’s spectral method) of ambient seismic noise has been widely adopted in surface wave phase velocity extraction. In two-dimensional cases, the surface wave velocity can be calculated by fitting the SPAC coefficients with the zero-order Bessel f...
