探讨了哈雷彗星接近地球与大地震发生的可能关系,特别列表说明了从14世纪以来哈雷彗星与8级大震的对应关系;作者并据此指出1986年哈雷彗星将再次接近地球,因此有必要引起人们的注意,特别要注意对中国西部强震的监视。第四篇介绍和分析了“美国1900—1979年重要地震图”,此图所示的1277次重要地震中,死亡人数≥10人或经济损失约1百万美元的共有682次,主要分布在欧亚地震带和环太平洋地震带上;文中指出欧亚地震带分布面积广、震源浅而且大震级地震比例较环太平洋地震带要多,其地震活动水平虽较环太平洋地震带要低得多,但地震造成的危害却要严重得多。
Explored the possible relationship between Halley’s comet approaching the Earth and a large earthquake. The special list shows the correspondence between the Halley’s Comet and the Magnaportrian 8 since the 14th century; the author accordingly states that Halley’s comet will again approach the Earth in 1986, so it is necessary Aroused people’s attention, with particular attention to the monitoring of strong earthquakes in western China. The fourth chapter introduces and analyzes “the United States 1900-1979 important seismogram”, this map shows the 1277 major earthquakes a total of 682 deaths ≥ 10 people or economic loss of about 1 million US dollars, a total of 682 times, mainly in Eurasian seismic belt and the Pacific Rim. It is pointed out that the Eurasian seismic belt has a wide distribution, a shallow source and a large proportion of earthquakes compared with the Pacific Rim, and its seismicity level is much lower than that of the Pacific Rim , But the damage caused by the earthquake is much more serious.
