【摘要】 以2011年尼勒克、巩留交界6.0级和新源、和静交界6.6级地震为例,研究了2次地震前周边的形变和流体资料临界慢化现象。首先,用小波变换方法对观测资料进行了预处理,然后计算了临界慢化现象的预警指标,方差和自相关系数,进而总结了2次6级地震发生前观测资料的临界慢化现象特征。结果表明,2次6级地震前出现了临界慢化现象。更多还原

【Abstract】 We study on critical slowing down precursor phenomenon through deformation and fluid data before two moderate earthquakes in Xinjiang. The characteristics of critical slowing down precursor phenomenon was found by calculating alarm signal,variance and autocorrelation coefficient. The results showed there is critical slowing down precursor before earthquake with M S 6. 0 in Xinjiang.更多还原
