【摘要】为探索数字化观测资料的前兆异常特征,进一步认识其映震能力,使得数字化观测资料在今后的地震分析预报中得到充分的利用。运用山西临汾中心地震台SSQ-2I石英摆、VS垂直摆倾斜仪、VP1、VP2宽带倾斜仪、水管仪、伸缩仪(侯马)的数字形变资料,用常规分析方法:形态法、矢量图分析总结了2010年10月24日河南4.7级、印尼苏门答腊7.3级地震的短临异常特征。更多还原

【Abstract】 In order to learn precursory anomaly characteristic of digital observation data and its earthquake reflecting ability further,and make digital observation data used fully in earthquake analysis and prediction,short-term and imminent anomaly characteristics of the Oct.24,2010 Henan earthquake of M4.7 and the Sumatra,Indonesia earthquake of M7.3 are summarized by using normal analysis methods,such as shape method and vector graph analysis,based on the digital deformation data of SSQ-2I quartz pendulum,VS vertical pendulum tiltmeter,VP1 and VP2 broadband tiltmeter,water tube tiltmeter and extensometer(Houma Seismological Station) of Linfen,Shanxi,Central Seismological Station.更多还原
