摘要
研究乌什台、阿合奇台、柯坪数字前兆观测资料,分析总结了2013年12月1日柯坪MS5.3地震前3个台站前兆资料异常特征。结果表明:震前乌什地震台水管仪、伸缩仪、新46井水位、体应变、钻孔应变、阿合奇地倾斜仪和柯坪钻孔倾斜仪数字前兆资料存在不同程度的前兆异常,短临异常主要以记录曲线出现阶变、畸变、变粗,趋势异常;以加速、转向的形变异常比较明显,以期总结震例,做好震情跟踪工作。
This paper researched Wushi, Akqi, and Keping seismic stations＇ digital precursory ob- servation data, analyzed and summarized precursory data anomalies of these three stations before Keping Ms5. 3 earthquake on December 1 st, 2013. Outcome turned out there existed varying degrees of precursory anomalies in digital precursory information of water tube instrument, extensometer, new 46 well water level, body strain, and boehole strain in Wushi seismic station, tilt meter on Akqi seismic station and inclinometer in Keping seismic station. Short- term anomalies mainly recorded step change, distortion and thick change, trend anomaly. Deformation anomaly mainly presented ac- celerating and turning. The writer tried to summarize earthquake cases and implemented earthquake tracking work.
