利用地磁垂直分量日变幅逐日比、加卸载响应比、地磁空间相关法,对2016年12月8日新疆呼图壁M_S6.2地震前震中周边的乌鲁木齐、克拉玛依、温泉地磁台记录的震前地磁异常特征进行了初步分析。结果表明:2016年12月8日在新疆呼图壁M_S6.2地震前,震中周围台站地磁资料出现明显的异常变化,属于短期异常。
Using the diurnal days-to-days ratio, loading-unloading response ratio and geomagnetic correlation method of geomagnetic vertical component, the records of the records of the earth stations in Urumqi, Karamay and Hot Springs before the epicenter M88 before the Hutubi Moutain of Xinjiang on December 8, 2016 Geomagnetic anomalies were analyzed. The results show that before the M_6.2 earthquake in Hutubi, Xinjiang on December 8, 2016, the geomagnetic data of the stations around the epicenter show obvious anomalous changes, belonging to short-term anomalies.
