五大连池火山区尾波Q值研究
|
摘要
选取五大连池火山地区2008年至2011年M_L>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Q(f)=(34.89±8.75)f~(1.0727±0.2253),表现为低Q高η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_0值为20.60,与国内外火山区尾波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 during the times between 2008 and 2011 which M_L>0.6 are selected.According to coda scattering theory and using Sato model,we calculate the 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 activity area.In the same time we also acquire coda = 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.
