摘要
本文报导了1981年以来,特别是1985年以来架设于楚雄观测站的电磁波接收器记录到的电磁波异常现象。后出,1985年一1987年4月停记前,以观测站为中心,400公里为半径范围内,发生了18次M_L>5.0级地震,有15次地震前记录到明显异常(其余3次异常不太明显,当作无异常)。结果表明,电磁波异常观测是一种有希望的临震预报手段。
This paper introduces the anomalous phenomena of electromagnetic waves occurred since 1981 and especially since 1985 registered by electromagnetic wave receivers installed at Chuxiong seismic station, Yunnan Province. 18 M≥5.0 earthquakes took place in the area with the observatory as its center and 400 km as the radius between 1985 and April 1987 when the instruments stopped operation. Prior to 15 out of the afore-mentioned 18 events, abvious anomalies had been registered, while the rest 3 events are regarded as ones having no anomalies because the anomalies were not very clear. The result obtained shows that observations of the electromagnetic wave anomalies might become a promising approach for earthquake predictions.
