| Abstract: | By use of the near shock waveform data from Hongshan digital seismostation and Handan digital seismological network from March, 2001 to July, 2006, QC values with different window length of coda waves 20 s,30 s, 40 s in Handan Xingtai region are calculated with Sato single scattering attenuation model, the average QC results in different time windows is 35.8 f 0.95,46.0 f 0.94 ,59.4 f 0.93 respectively. In the studied area ,Q0 value affected by tectonic factors shows obviously lateral heterogeneity,generally,Q0 value is lower, η value is higher, QC value strongly depends on the frequency and decreases rapidly with the frequency’s in creasing. |
