摘要
利用地震地磁分析方法及形态分析方法,分析2017年5月11日新疆塔什库尔干M_S5.5地震前兆资料异常特征。结果表明:喀什地磁和伽师55井深层水温均出现明显的短期异常变化,主要表现为:(1)喀什地磁垂直分量逐日比、加卸载响应比均出现超限的高值异常;(2)中国大陆地磁台站在此次塔什库尔干M_S 5.5地震前出现低点位移突变分界线;(3)伽师55井深层水温出现弯曲型低值异常。
The comprehensive character of geomagnetic anomaly in Kashi, Jiashi No.55 well geomagnetic Station to Tashikuergan MS 5.5 earthquake on May 11, 2017 has been refected and analyzed with geomagnetic Z component daily ratio, geomagnetic load-unload response ratio, geomagnetic low-point time, morphological analysis methods. It is found that the precursor showed obvious middle and short-term anomalies.
