%X Different from the traditional method of estimating seismic attenuation based on the waveform of single event,we regarded a series of events as an equivalent one,and obtained seismic attenuation on the basis of cross-correlation function between source and signal recorded at distance.We performed a field experiment by the end of 2004,and based on the data of this experiment,we studied the amplitude degression and corresponding seismic attenuation factor of both single event waveform and cross-correlation function.It is found that,same as single event waveform,cross-correlation function could be used to assess the seismic attenuation.The results show:(1) Q of in-situ medium is about 40;(2) Amplitude degressions with distance of single event waveform and cross-correlation functions are much similar.
