| 摘 要： | 本文引入地壳波导理论,对1979年7月9日江苏溧阳6级地震前南京卫岗电磁信息观测点所记录到的超低频电磁波信号进行研究,估算出接收点的场强为10~2—10~3微伏/米。辐射源电流矩为10~7安·米。

ESTIMATION OF THE INTENSION GRADE OF ELECTROMAGNETIC WAVE EMISSION SIGNAL BEFORE THE LIYANG EARTHQUAKE |
| |
| Abstract: | This paper introduces the theory of wave guide for studying the ULF electromagnetic wave signal which were recorded by the observational station in Nanjing before the Liyang (Ms=6) earthquake on July 9, 1979. The estimated intension of the electromagnetic wave signal is about 10~2—10~3 uv/m at the receiving station, and the estimated currentmoment of radiation source is about 10~7 A. m. |
