本文利用阿克苏台网中心前兆观测数据,采用动态分析、形态法对新疆阿图什市Ms5.2级地震和于田县Ms6.2级地震进行了系统分析。发现在这两次地震前,阿合奇台地倾斜资料、乌什台水管倾斜资料、伸缩仪资料、体应变及辅助测项钻孔水位和静水位数据、地电数据均出现了明显的震前异常。其中水管仪、伸缩仪、体应变、地倾斜趋势异常表现为打破年变,水管仪短临异常表现在震前几天出现高频抖动、日变形态畸变;体应变辅助测项钻孔水位和静水位数据、地电数据在震前则表现为突变。
In this Paper, Combined with the precursory observation data of Akesu Central Seismic Station, the method of dynamic analysis and morphological are used to comprehensively analyze the Xinjiang Atushi city Ms 5.2 earthquake and Yutian County Ms 6.2 earthquake. According to the study, found that the Ground Inclinometer data of Akqi Seismic Station, the Water Tube Tiltmeter data, the Extensometer data, the Volumetric Strain data and it’s auxiliary measuring water level data in boreholes, the Static water level data and the Geoelectric data of Wushi Seismic Station emerged obvious precursory anomalies before the two earthquakes. The trend anomaly of the Water Tube Tiltmeter data, the Extensometer data, the Volumetric Strain data and the Ground Inclinometer data expressed as break the annual variation. The short-term anomaly of the Water Tube Tiltmeter data appeared as high-frequency jitter and shape distortion of the diurnal variation in the days before the two earthquakes. The Volumetric Strain Auxiliary measuring water level data in boreholes, the Satic water level data and the Geoelectric data manifested as mutation before the two earthquakes.
