【摘要】 我们考察了发生在中国的11个具有代表性的地震后发现,地震前地磁短周期转换函数的帕金森矢量或韦氏矢量指向震中方向,转换函数|A|或|B|值明显偏离正常值以及总误差δ_z显著增大,均为未来地震的发生和震中方向提供了判断依据。应用此法,我们成功地预报了M_s5.1地震。 中国地震科技工作者认为,震前地磁短周期变化异常是客观存在的,物理基础是清楚的,是有希望的地震短临预报方法。更多还原

【Abstract】 Eleven representative earthquakes occurred in China were taken as examples, and we found that Parkson or Wiese vector would point to the epicentral direction and the obvious deviation of the value of transfer function |A| or |B|; increase of the overall error <δz may be regarded as the criteria of the forthcoming earthquakes.A successful prediction of an earthquake with M=5.1 was made by using this method.Chinese seismologists realize that anomalies of geomagnetic short periods exist objectivety, and the physical idea is clear and those anomalies could serve as precursory signals to predict the impending earthquakes.更多还原
