【摘要】 利用单台叠加谱比法（SSR）分析钟祥台记录的周边地区30个地震事件的垂直分量,得出与各个射线对应的Lg波尾波的Q₀值。结果表明,Q₀值的大小与构造活动强弱有关,在构造活动强烈的胡集-沙洋断裂、通城河断裂、天阳坪断裂、青峰断裂附近呈现出低值,约在130～200范围内变化;在远离断裂的区域,构造活动比较稳定,Q₀值达到600以上。更多还原

【Abstract】 We use the stack spectral ration method to explore thirty vertical components of earthquake data recorded by Zhongxiang seismic station, gaining the corresponding Q₀ values of coda wave of Lg-wave for each radiation path. Results show that the values of Q₀ have to do with the tectonic activity. In the active regions among Huji-Shayang fault, Tongchenghe fault, Tianyangping fault and Qingfeng fault, the Q₀ manifest low values change from 130 to 200, but away from the activity regions of fault, the tectonic activity is stable, and Q₀ is as high as 600.更多还原
