地震危险区 meaning in Chinese

earthquake prone region
earthquake risk region
earthquake-prone area

It is shown that expansion of the warning area may apparently enhance the " successful ratio " of earthquake prediction
结果表明，将所划定的地震危险区适度扩大，即将现有的地震危险区范围向外扩大约0 . 5 ，可以显著地提高预测地震的“命中率” 。
Whether earthquakes at the edge of the warning area can be considered as successfully predicted is one of the controversial problems in earthquake prediction study
摘要对位于地震预测工作所圈定的地震危险区附近的地震的统计检验问题，一直是地震预测研究中一个颇有争议的问题。
In the research of earthquake forecast , continuous observation on the stress changes and the changes of stress direction should be sufficiently regarded in a danger region happening structural earthquakes
在地震预测研究中，既要重视对地震危险区块内的应力大小变化的实时观测，亦要重视对地震危险区块内应力方向变化的实时观测。
