利用Sato模型研究宁夏及邻区尾波Q值分布特征
The research on distribution characteristics of coda wave Q value in Ningxia and adjacent region based on the Sato model
摘要
Abstract
Based on the Sato model,565 earthquakes digital wave data above ML 2.0 from January, 2008 to December,2013 are adopted,which was recorded by Ningxia Earthquake Nets. The selected waveform records are clear and the noise levels meet requirements. By calculating the coda wave Q value of every area in Ningxia and adjacent region and comparing existing results, the distribution characteristics of coda wave Q value are obtained. The results show that the coda wave Q value in the north is higher than that in the south;The coda wave Q value in Wuzhong and Lingwu is relatively high,which corresponds with its high speed zone;Coda wave Q value of the southwest of Alashan Zuoqi is relatively low;Coda wave Q value in Yanchi is rather higher than other regions because of its steady geological structure. Coda wave Q value in Zhongwei, Haiyuan and their nearby regions is relatively high,and it is thought to be associated with the high temperature and heat-lfow value in the deep crust of the area.关键词
