| 摘 要： | 挑选出2013年10月31日至12月31日前郭地区发生的58次M1.0以上地震事件,基于Sato的单次散射模型分别计算了长岭台、松原台和乾安台的尾波Q值,获得了3个台尾波Q值与频率的依赖关系,分别为：Qc=33.65f^0.9782、Qc=33.00f^0.9104、Qc=33.46f^1.0299。初步认为研究区内的Q值在2~18Hz范围内与频率有显著的相关性,研究区内的低Q值现象与该区地质构造、地震活动性形成了较好的一致性。

| 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 sta- tions,they are respectively ： Qc=33.65f^0.9782,Qc=33.00f^0.9104,Qc=33.46f^1.0299. 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 a good coincide with the tectonic structure and earthquake activities in the study area. |
