摘要
为研究地震异常,对南天山西段地球物理观测资料进行分析,喀什台地磁、乌恰钻孔倾斜的资料变化与2020年1月19日新疆伽师M_(S)6.4地震有关。(1)喀什台地磁秒数据垂直强度极化法、Z分量日变幅加卸载响应比均出现超阈值的高值异常;(2)乌恰钻孔倾斜EW分量2019年5月12日~11月24日反向东倾,异常幅度达到4.54″,随后恢复正常西倾变化。
Based on the analysis of geophysical observations in the western part of South Tianshan,the data changes of Kashgar geomagnetism and Wuqia borehole tilt are related to Jiashi M_(S)6.4 earthquake in Xinjiang on January 19,2020.(1)The vertical intensity polarization method of Kashgar geomagnetic second data and the loading and unloading response ratio of daily variation amplitude of Z component all have high value anomalies exceeding the threshold;(2)From May 12 to November 24,2019,the EW component of borehole tilt in Wuqia tilted reversely to the East,with an abnormal amplitude of 4.54″,and then returned to the normal West.
