近年来,国内研究结果相继指出,某些特殊部位小震活动频度的增高与一定范围内其后短期发生的大震有关。于是认为,这种特殊部位小震活动频度的变化,可以作为监视区域构造应力场增强或减弱的“窗口”或“窗”或前兆敏感点(下称“窗口”)。 1984年全国地震学前兆方法清理的结果,在全国范围内的不同地区找寻出若干个

In recent years, the results of domestic research have pointed out successively that the increase of the frequency of small earthquakes in some special places is related to the short-term earthquakes that occur in a certain range afterwards. Therefore, it is considered that the frequency of small earthquakes in this special part can be used as the “window” or “window” or precursory sensitive point (“window”) in which the stress field is enhanced or weakened in the monitoring area. In 1984, the results of the National Seismological Premonition Method were cleared, and several different areas in the whole country were found out
