| 摘 要： | 利用常规分析方法研究了新疆部分4级和5级以上地震前地倾斜资料所出现的短期和临震异常变化,统计了异常开始至发震时间、异常持续时间、异常结束至发震时间、异常量级及异常形态等,通过对典型震例的剖析得出了中强地震和远场强地震前的地倾斜短期异常特征。在地震前的短临阶段,异常的项数和异常量级急剧增加;震级不同,异常起始时间和发震的优势时段也有所不同。

| Abstract: | Short-term and impending anomalies of ground tilt before some M_S4.0 and M_S5.0 earthquakes in Xinjiang are analyzed by routine methods.The statistical data such as the period between anomaly initial time and earthquake,the anomaly duration time,the period between anomaly ending and event,the anomalous amplitude and the anomalous shape are summarized.Through analyzing the typical cases the short-term anomalous features of groud tilt before moderate-strong earthquake and strong earthquake in a far distance are presented in the paper.In the short-impending period before event,the number and amplitude of anomalies increase quickly,the anomaly initial time and the predominant period for event occurring are different in different magnitude of events. |
