摘要
根据华南地区10次5级以上震例分析结果,得到了与理论分析一致的认识,即地下流体能灵敏地显示短临地震信息,特别是地震发生的时间信息,但不能较好地显示震中方位信息。然而,短临地震时间信息对于地震短临综合预报及防震减灾决策具有重要意义。
Based on the analysis of observed data before and after 10 earthquakes with M s≥5 0 of South China, the acquaintance accordance with the theoretical analysis has been abtained in this paper.That is the subsurface fluid could show thort-term and impending information of earthquake,espacial the information about time,but could not show the information about epicentral azimuth. It is very significate for the decision of earthquake prediction and the protection and the mitigation of seismic hazard.
