备注

2016—2017年华南地区地磁分析方法预测指标体系初步建立,包括地磁低点位移法、地磁加卸载响应比法、地磁逐日比法和地磁测深视电阻率法,介绍了这些方法指标体系建立以来,华南地区5级以上地震前这些方法的异常情况,分析和讨论了地磁异常与地震间的关系,并对华南地区地磁预测指标的改进和应用给出了建议。
From 2016 to 2017, the prediction index system of geomagnetic analysis methods in South China was preliminarily established, including geomagnetic low point displacement method, geomagnetic loading and unloading response ratio method, geomagnetic daily ratio method and geomagnetic sounding apparent resistivity method. This paper introduces the anomalies of these methods before earthquakes with M≥5 in South China since the establishment of the index system of these methods, analyzes and discusses the relationship between geomagnetic anomalies and earthquakes, and gives suggestions for the improvement and application of geomagnetic prediction indexes in South China.
