摘要
将地震强度因子 Ｍｆ 值用于华南和东北地区地震的中期预报， 以检验 Ｍｆ值在上述地区对 Ｍ Ｓ≥５０ 级以上地震的预报效果。结果表明， 震前２ ～３ ａ 开始震中周围区域一般都出现明显的 Ｍｆ 值中期异常区， 表明 Ｍｆ
The seismic magnitude factor M f-value is uesed to earthquake medium term prediction in the South China and the Northeast China for testing the effect of forecasting earthquakes of M S≥5 0 in these regions in this paper.The results show that the medium-term anomaly zones of M f-value appear obviously around the future epicenters before strong earthquakes 2～3 years.It means that M f-value has better prediction effect for moderate or strong earthquakes in the South China and the Northeast China.
