| 摘 要： | “已知地点信息”指根据华南地区历史地震活动分布特征，将华南地震活动区划分为老震区、水库区和小震活动区。本文分析了华南地区以上3种区域1980年以来22次已知地点信息的ML≥5.0地震事件前的地震活动现象，总结探讨了各区中强地震前的异常特征:水库区表现为震中的地震平静—增强，老震区和小震活动区则为区域的地震增强—活跃—平静。综合以上分析研究，提出了华南已知地点信息的地震预测对策。

| Abstract: | In this paper we analyzed the earthquake activity characters of 22 known-location events with ML ≥ 5.0 in the South China area since 1980, and discussed the anomaly characteristics before the moderate-strong earthquake in old earthquake area, reservoir area and earthquake swarm area. In reservoir area the earthquake activity is characterized by quiet to strong tendency, whereas, in other areas earthquake activity shows strong-active-quiet tendency regionally. Based on the research results, we put forward the earthquake prediction countermeasures for known location information. |
