山东中西部及邻近地区震源参数和场地响应的反演

INVERSION OF SOURCE PARAMETERS AND SITE RESPONSE IN CENTRAL AND WESTERN SHANDONG AND ITS ADJACENT AREA

摘要: 利用山东数字地震台网10个地震台自2004年6月至2007年8月记录的数字波形资料,采用Atkinson(1992)方法反演了山东中西部及邻近地区的非弹性衰减,得到该地区Q值与频率的关系是Q(f)=382.2°f^0.443。运用Moya(2000)方法反演了10个台站的场地响应,得到了26个地震的震源参数,并对所得结果进行了初步讨论。

Abstract: Based Atkinson(1992) method, the nonelastic attenuation in Central and Western Shandong and its adjacent areas was inversed with the digital seismic wave data recorded by 10 stations in Shandong digital seismic network from June 2004 to August 2007, and the relation of Q value with frequency we got is Q(f)=382.2°f^0.443.Site response of 10 stations was inversed with Moya(2000) method, and the focal parameters of 26 earthquakes were got.The results were simply discussed.
