摘要
对《中国震例》中全国范围内200余次5级以上震例的伤亡情况进行统计分析,发现发震时间、地点和震级都是地震伤亡的重要影响因素。在非无人区,在北京时间00~06点这一时段发生的地震,造成的伤亡人数要比发生在其它时段的伤亡人数多得多;震中在城市、县城和人口密集区的地震,造成的死伤人数要比发生在其它地方的多得多;震级越大,平均伤亡人数越多;发震时间、地点和震级不同的组合造成的伤亡不一样,三者共同作用的结果,可能无伤亡,也可能伤亡很大。
Based on Cases of Chinese Earthquakes, the casualties caused by more than 200 earthquakes with M≥5.0 are analyze statistically. The result shows that seismic time, location and magnitude are all the important influential factors on casualty. In residential areas, the casualties caused by the earthquakes that occur between 0:00 ~ 6:00 AM are more than those in other times; the casualties by the earthquakes that occur in cities, county towns, dense population areas are far more than those in other places; and the greater magnitude is, the more average casualty is. The casualty varies due to different combination of seismic time, location and magnitude, may be serious, or zero.
