摘要
利用小波方法,梳理2016年12月8日呼图壁M_S6.2地震前新疆地下流体资料,发现震前水位、水温、逸出气体等均出现异常变化。分析了异常的时间分布、空间展布和异常成因。结果表明,地下流体的中期异常不是源兆,而是与区域构造活动密切相关。
Taking wavelet method,this paper studied underground fluids of Xinjiang before Hutubi earthquake with M_S6. 2. It showed that there were obvious anomalies such as water level,water temperature and exhaust gas. It analyzed time change,spatial distribution and origin of anomalies. Results showed that the medium term anomalies of underground fluid were not source precursors,but closely related to regional tectonic activities.
