阿图什市5.2级地震与于田6.2级地震前兆异常分析
The precursory anomaly analysis of the Atushi Ms 5.2 earthquake and Yutian Ms 6.2 earthquake, Xinjiang
摘要
Abstract
In this Paper,Combined with the precursory observation data of Akesu Central Seismic Station,the methods of dynamic and morphological analysis are used to comprehensively analyze the Xinjiang Atushi city Ms 5.2 earthquake and Yutian County Ms 6.2 earthquake.According to the study,it is 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 Static water level data and the Geoelectric data manifested as mutation before the two earthquakes.关键词
