本文研究了中国和全球大地震能量释放与地球自转变化的关系,分析了中国大地震活动的时间和空间分布特征。根据中国大地震能量释放主要集中在地球自转角速度相对变化曲线的中段,我们推测,八十年代末至九十年代初,中国西部地区特别是西北地区有可能发生特大地震。 This paper studies the relationship between the energy release in China and the world and the Earth’s rotation, and analyzes the temporal and spatial distribution characteristics of the large earthquakes in China. According to the fact that the energy release from the Great China Earthquake is mainly concentrated in the middle of the curve of the relative angular velocity of the Earth’s rotation, we speculate that it is possible that a large earthquake may occur in the western part of China, especially in the northwest China in the late 1980s and early 1990s.
