- Abstract:
-
The coda-wave-attenuation-quality factor Q0 in Yunpeng Hydropower Station area and its adjacent regions is estimated using Aki's single-scattering attenuation model based on 108 local seismic events recorded by 5 regional digital seismic stations from January 2000 to December 2008.The result shows that the relationship between Q0 and f can be described as Qc(f)=90.2f 0.94.Compared with the ones in other areas of Yunnan with strong tectonic seismic activity,the values are higher in this area with moderate tectonic activity.The Q0 and Qc values declined a little after the Yunpeng reservoir impounded water; this means that the water storage has influenced the medea character in this area,but the effect is limited.
