嘉峪关水管倾斜仪观测资料映震能力分析
|
摘要
分析嘉峪关西沟形变DSQ水管倾斜仪2008年1月-2010年12月观测资料,利用形态分析法、日均矢量法、M_2波潮汐因子动态分析方法,分析水管倾斜仪NS、EW分量,研究观测异常与周边M_S 5.0以上中强地震的关系。结果表明,该台水管倾斜仪对周边中强地震有一定短临异常显示,对较远处中强地震也有明显的趋势异常显示。
The deformation data of DSQ water tube tiltmeter at Xigou.Jiayuguan from 2008 January to 2010 December are analyzed,using morphological analysis,the average vector method,the tide factor of M_2 wave and dynamic analysis method.The water tube tiltmeter NS,EW component is analysed to study the relationship between observed anomaly and the moderately strong earthquakes surrounding with the magnitude more than M_S 5.0.The results show that there is imminent abnormal display of the water tube tiltmeter to the surrounding medium strong earthquakes,and obvious trend anomaly to the teleseism
