| 摘 要： | 本文介绍了张掖地区电磁波观测点观测到的几次地震前的电磁波异常。这些异常一般出现在震前几小时、几天至十几天,信号一般呈低频扰动或频率稍高的连续双向强脉冲型。观测结果表明,电磁波异常可以作为一种地震的短临预报指标。

| Abstract: | This paper introduces electromagnetic wave anomalies before some earthquakes observed at some observing points in Zhangye region, Gansu Province. These anomalies generally appeared a few hours, some days to more than ten days before earthquakes. The signals of electro-magnetic wave anomalies are low-frequency disturbances or continuous bidirectional strong pulses with higher frequency. The results observed show that electromagnetic wave anomaly can be regarded as a shortterm and imminent predicting index of earthquake. |
