根据历史地震资料,新疆及其邻区的地震活动大致可以分为三个地震期,即1716—1811年,1812—1901年和1902年后。自1882年以来的强震活动可以划分为五个活动幕和五个平静幕。 自1820年,尤其是20世纪以来,新疆及其邻区的强震活动与地球自转相对速率变化有明显的关系。根据统计分析,估计了本世纪末及21世纪初强震活动的潜在震源区及地震危险性。
According to historical seismic data, the seismic activity in Xinjiang and its adjacent areas can be roughly divided into three seasons, that is, from 1716 to 1811, from 1812 to 1901 and from 1902 onwards. Earthquakes since 1882 can be divided into five activity screens and five calm screens. Since 1820, especially since the 20th century, the seismic activity in Xinjiang and its adjacent areas has a clear relationship with the relative rate of change of the Earth’s rotation. According to the statistical analysis, the potential source regions and seismic hazards of strong earthquakes at the end of this century and the beginning of the 21st century are estimated.
