摘要
从中等地震震源机制解,地震活动的空间分布和时间分布等方面研究了甘肃九甸峡水库库区及邻近地区的地壳应力场和地震活动特征.其结果为估计九甸峡水库蓄水后发生诱发地震的可能性和可能的最大震级提供了基础依据.
The characteristics of crustal stress field and seismic activity of the Jiudianxia reservoir and its nearby area in Gansu province have been studied according to the source mechanism of moderate earthquakes and the temporal--spatial distribution of seismic activities. The results provide a foundation for the estimation of the possibility of seismicity induced by water impounding and the maximum magnitude.
