摘要
自1979年以来,江苏地磁垂直分量台网已进行了十年的连续观测和试验。在上述时间内发生的三次M_s>5.0级地震前都观测到地磁垂直分量异常变化。这种异常在平时是不出现的。 作者认为,在中低纬度地区,用较密集的连续观测垂直分量台网能更有效地捕捉到地震磁异常信息,以改善地磁方法预报地震的效果。
Since 1979 a dense network of geomagnetic stations had been set up for observing the seismo-magnetic effects in Jiangsu Province. Anomalous changes in the vertical component were successfully observed before recent three earthquakes of Ms>5. 0. such anomalous changes had never been observed during the period without earthquake of Ms>5. 0. It is suggested that the geomagnetic vertical component is more sensitive than the total intensity in detecting the seismo-magnetic effects, particularly in the low and middle latitudes.
