摘要

利用空间扫描方法研究了华北地区中强以上地震前地震非均匀度GL值的中短期异常变化特征 .结果表明在中强地震前 1年左右 ,未来震中周围的GL值中期异常区通常出现明显的收缩或消失 ,一些地震临震前数月还再次出现GL值异常区 .讨论了使用GL值进行地震中短期预报的有关问题
The seismicity data of moderate or small earthquakes in North China are used to space scanning of seismic inhomogeneous degree GL value. Characteristics of mid short term anomalous changes of the value before mid strong earthquakes in the region are studied. The result shows that the mid term anomalous area of the GL value obviously contracts or disappears in mid short term of about 1 year before moderate or strong earthquakes in generally. The anomalous area appears again in several months before some earthquakes. Some problems about mid short term prediction by using the GL value are also discussed.
