摘要： 从非线性观点出发,研究了15次后续强震前较大地震发生的特点。 研究结果表明,后续强震前 2次较大地震地方平太阴时夹角b.r小于45。,以及 2次较大地震震级呈上升趋势是判断 后面是否发生强震的 2 个指标。

Abstract: The features of larger earthquakes before 15 subsequent strong earthquakes are stud 1ed in this paper from the nonlinear viewpoint. Two useful indexes to judge the subsequent strong earthquakes are discovered. The two indexes are: 1. The included angle Aτbetween local mean lunar times of two larger earthquakes before the subsequent strong shock will be smaller than 45°; 2. The magnitude of the late larger earthquake is higher than the former one.

Key words: Nonlinearity, Solid tide, Earthquake prediction, Subsequent strong earthquake
