A PRELIMINARY ANALYSIS ON THE CHARACTER OF THE DISTRIBUTION OF GLOBAL EARTBQUAKES IN LATITUDE AND THE PEAK ABNOMALY NEAR LATITUDE 35°N

    摘要
  • 摘要: 本文取1900年-1980年全球Ms ≥ 6.0地震7936次分析后发现,地震发生在南北回归线(23°5N-23°5S)之间占49.69%,发生在南北极因(63°5N-63°5S)之间占99.17%,发生在南北极圈外只占0.83%,即很少发生地震;其中8级地震98次,在35°N线为高峰。又分析了公元648年-1979年全球M ≥ 8级地震257次主要亦集中在35°N线附近。尤其是历史上破坏性极大的地震在35°N线附近者多。这些现象可能和地球自转有一定关系。

     

    Abstract: This paper analyzed 7936 earthquakes (Ms>6.0) occurred from 1900 to 1980 A. D.. We found that 49.6% earthquakes occurred between the Tropic of Cancer and the Tropic of Capricorn, and 99.17% earthquakes between the Arctic Circle and Antarctic Circle. There are only a few earthquakes (0.83%) occurred in the polar region. We also analyzed 257 earthquakes (Ms>8.0) occurred from 648 to 1979 A. D. and found that most of them occurred near latitude 35°N. The destructive earthquakes occurred in history are also occurred near latitude 35°N. perhaps, these phenomena have relation to the rotation of the earth.
