摘要
一种新的临震异常──地倾斜脉动群自１９８８年以来已出现３１次，作出短临预报的有１５次，显示出较大的临震预报作用。这种脉动群可能是孕震后期地壳断裂加速活动时产生的一群压性和压扭性小裂隙的外在标志．
A sort of new impending earthquake anomaly-the dip pulsation cluster,since 1988, has appeared 31 times. I have made impending earthquake forecast 15 times.So,I think we should pay attention to the pulsation cluster.The pulsation cluster perhaps is a sign of compressible and twisting-compressible small cracks and microcracks. The small cracks and microcracks are formed by accelerated motion of the crust fault in last period of seismogenic term.
