【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=33.65f0.9782、Qc=33.00f0.9104、Qc=33.46f1.0299。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。更多还原

【Abstract】 Using 58 M≥1.0earthquakes 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=33.65f0.9782,Qc=33.00f0.9104,Qc=33.46f1.0299.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.更多还原
