- 摘要:
- 选取五大连池火山地区2008年至2011年间ML＞0.6火山地震事件39个，根据尾波散射理论，利用Sato模型计算其尾波Q值，获得整个火山区尾波Q与频率F关系 ，表现为低Q高 值的火山构造活动活跃区域尾波特征，同时获得老黑山、火烧山附近区域尾波Q值20.60，对计算结果与其他国内外火山区尾波Q值加以对比，对本区域地震活动性进行了分析，并结合本区其他火山研究成果给予简单解释。
39 volcanic earthquake events occurring in Wudalianchi volcanic area and during the times between 2008 and 2011 which Ml>0.6are selected, According to coda scattering theory and by using Sato model, we calculate the Q value and then acquire the formulation which is between coda and frequency in the whole volcanic area. it show low and high value which coda feature is in active volcanic tectonic movement area. In the same time we also acquire coda Q =20.60 in the nearby area of LaoHei mountain and HuoShao mountain. Furthermore we analyze our result by comparing with from other domestic and exotic area and give some brief interpretation by linking with other volcanic research achievement
