Abstract:
Using 58
M≥1.0 earthquakes in Qianguo between Oct.31 to Dec.31,2013,we calculated the Coda Q-value of Changling station,Songyuan station and Qianan station with the Sato single scattering model,We got the dependency relationship of Coda Q and frequency for the three digital observation stations, they are respectively:
Qc=33.65
f0.9782,
Qc=33.00
f0.9104,
Qc=33.46
f1.0299.The result indicate that the Coda Q was a bit low and had a high dependency with frequency during 2-18 Hz,this phenomenon had agood coincide with the tectonic structure and earthquake activities in the study area.
