近年来,地震预报的地震学方法清理结果表明,利用地震空区预报未来强震有一定的效果,但是虚报率较高。作者研究发现,在一些没有发生地震的孕震空区周围,发生了某种“卸载地震”,以至终止了空区的孕震过程。文中总结了某些卸载地震的特点和利用对卸载地震的识别从而减少虚报的效果。卸载地震的作用有可能对其它无震前兆异常提供解释。
In recent years, the seismological method of earthquake prediction results show that the use of seismic areas to predict future earthquakes have a certain effect, but a higher false alarm rate. The authors found that some “unloading earthquakes” occurred around some uncontrolled earthquake-stricken areas, ending the seismogenic process in the open area. The article summarizes the characteristics of some unloading earthquakes and uses the recognition of unloading earthquakes so as to reduce the effect of false reporting. The role of unloading earthquakes may provide explanations for other anomalous precursorless earthquakes.
