本文依据4个大震的实际观测资料讨论了地震前兆异常幅度随震中距成非线性变化的现象,发现其异常幅度峰值往往并不位于震中,而是位于震源体边缘地带。进而首次提出利用这种地震前兆异常幅度峰值围空作为预报地震发生地点的一种可能途径。
Based on the observed data of four major earthquakes, this paper discusses the phenomenon that the amplitude of anomalous earthquake precursors changes nonlinearly with the distance between epicenter and epicenter, and it is found that the anomalous amplitude peak is not located in the epicenter but located at the edge of the epicenter. It is the first time to put forward a possible way to predict the occurrence of an earthquake by using this peak amplitude of the anomalous amplitude of earthquake precursors.
