关于本世纪前80年地震死亡人数统计规律的研究报告,指出:死亡数较多的地震主要出现在12月,其次是5月和9月;它们一般发生在北纬35至40度间;从死亡人数和震级的关系中找到一条限制线,可用以粗估未来在陆地上发生地震的死亡人数上限,太阳黑子呈趋势性下降时发生大地震较多,随之死亡人数明显增多;此文附有死亡千人以上的地震统计表,并据此制成震级和死亡人数的关系图。
A study on the statistical laws of death tolls in the first 80 years of this century states that the earthquakes with the largest number of deaths occurred in December and secondarily in May and September; they generally occurred between 35 and 40 degrees north latitude; The relationship between population and magnitude found a limit line that could be used to estimate the upper limit of the number of earthquakes that would occur on the land in the future. When the trend of the sunspots decreased, there were more large earthquakes and the number of deaths increased significantly. Earthquake statistics of more than a thousand people, and according to the relationship between the magnitude and the death toll.
