备注

经多年观测发现,巧家毛椿林水点的宏观、微观前兆异常变化同该水点100 km范围内5.0级左右的区域地震具有较高的一致性。通过对选择的部分微观前兆观测资料进行日均值常规处理,对宏观异常情况进行归类总结,发现氟离子、钙离子指标异常以及宏观水位变化异常是对应区域地震预测的良好判定指标。

After years' observation,we find that the anomaly of Maochunlin observation point is in conformity with regional earthquake about 5.0 in the range of 100 kilometres.In this article,we chose some seismic precursory data to get day average,and at the same time we classify and summarize the macroscopical anomaly.Then we draw a conclusion that the macroscopical water level and the concentration of Ca+ and F+ are good indicator for regional earthquake forecast.
