| 摘 要： | 探讨了北部湾地震地磁和气象的异常现象，初步结果表明，震前几个月至数天，地磁垂直分量的相关系数ｒ值，特征线斜率Ｋ值以及Ｚ日变形态双低点位移先后出现短临异常，气象因子分析结果表明，年雨量一阶差分大于４００ｍｍ可作为５级以上地震的年度预报参考指标。震前数月，－３．２ｍ的地温年变形态出现畸变。

| Abstract: | The anomalous phenomenons associated with the geomagnetism and meteorologic before Beibuwan earthquakes are discussed.The initiative result shows that some of the geomagnetic parameters were abnormal sequentially from almost half a year to several days before the earthquake,such as the gradient(K) of geomagnetic characteristic line,the correlation coefficient(r) on geomagnetic zcomponent and the displacement of "Double bottom" on day range of z-component. Meanwhile,the analySis of meteorological factors indicated that before the earthquake those had some changes,such as the precipitation and ground temperature at the depth of-3.2 meters et al. |
