| 摘 要： | 六年来,我们用无阻尼水平摆地倾仪,在1.7秒—5秒的周期范围内,在一系列的强震发生前,分别记录到了一种明显的波动异常。並用它对不少的强震,诸如1976年8月16日松潘7.2级地震、1976年11月7日盐源6.9级地震,作了比较好的临震预报。实践证明这是一种有苗头的临震前兆。本文是对六年来探索工作的一个总结,並对其成因机制作了初步的探讨。

| Abstract: | Since 1976, by using the non-damping horizontal pendulum tiltmeter at the range of 1.7"-5" period. we have recorded one wave anomaly signal before a series of strong earthquakes respectively. And by means of it we Predicted some strong earthquakes, such as Song pan earth quake (8.16.1976, Ms=7.2) and Yanyuan earthquake (11.7.1976, Ms=6.9). The practice of seismic prediction has proved that the wave anomaly is a possible earthquake precursor.This paper is a conclusion of our detection during 1976-1982, and a preliminary discussion on the genetic mechanism of the wave anomaly. |
