北天山泥火山对2012年6月30日 新源-和静MS6.6地震的响应

Responses of mud volcanoes in the North Tianshan to the 30 June 2012 Xinyuan-Hejing MS6.6 earthquake

  • 摘要: 2012年6月30日新源-和静MS6.6地震前后, 北天山泥火山出现了喷溢和地球化学异常变化. 该地震前、 后4天内两次观测了北天山泥火山, 采集了两批温泉和泥火山气体样品, 测定了样品的气体组分和He、 Ne同位素及CH4、 CO2的碳同位素组成. 结果表明, 泥火山发生了同震喷发, 气体排放量增加, 温泉和泥火山气体出现了不同程度的微量气体浓度异常, 独山子泥火山震前出现了3He/4He高值异常. 研究结果有利于确定利用泥火山和温泉监测地震活动的方法和指标.

     

    Abstract: Eruption and geochemical anomalies of mud volcanoes in the North Tianshan were found before and after the 30 June 2012 Xinyuan-Hejing MS6.6 earthquake in Xinjiang Uygur Autonomous Region (Xinjiang), northwestern China. The mud volcanoes in the Northern Tianshan were surveyed, and the gas samples from the hot springs and mud volcanoes were collected twice in four days before and after the earthquake. Concentrations of gaseous components and isotopic compositions of CH4, CO2 and He, Ne were measured. The data indicated that the mud volcanoes coseismically erupted, amount of gas emissions increased, and anomalies of trace gas concentrations appeared in the hot springs and mud volcanoes in different levels. High-value anomaly of 3He/4He in the Dushanzi mud volcano occurred before the earthquake. Results are favorable to selecting the indicators for monitoring seismic activities in the study area by using hot springs and mud volcanoes.
