本文对临震前地倾斜跃变异常的基本记录特点、跃变达到峰值后发震时间关系及跃变矢量与发震方位的关系等作了初步探讨。得到了以下三点认识: (1)地倾斜跃变异常从出现到峰值这段时间的两倍加一个常数便是未来地震的发震时间。(2)地倾斜跃变的矢量方位多指向或背向震中。(3)地倾斜跃变异常持续时间越长,幅度越大,一般发震的震级就越大。 This paper makes a preliminary study of the basic characteristics of the anomalous tilt transition before the pre-quake, the relationship between the onset time after the peak of the jump and the relation between the transition vector and the seismogenic position. Got the following three points of recognition: (1) ground tilt jump anomalies from appearance to peak twice this period plus a constant is the future earthquake seismogenic time. (2) The azimuthally directed vectorial azimuths are directed or backwards to the epicenter. (3) The longer the slope leaning anomaly, the greater the amplitude, the greater the magnitude of the general seismogenic shock.
