唐山地区尾波Q值时空分布特征
Temporal and spatial distribution characteristics of the coda wave Q value in Tangshan region
摘要
Abstract
The coda wave Q values in Tangshan region is calculated by fixed the window length of the code wave based on Sato single scattering model,using the seismic waveform data recorded by the Digital Seismic Network in Capital Circle from January 2009 to March 2016.The distribution characteristics of Q values were analyzed in time and space,respectively.The results show that,the spatial distribution of Q values show significant lateral heterogeneity,Q values exhibit the process of increasing-reducing-re-elevating-shocking over a longer earthQuake preparation time,and the moderate earthQuake tends to be happened in the side of high values of the border zone of high and low Q values,the earthQuake swarm tends to be happened in the region where Q values are relatively low.关键词
