| 摘 要： | 计算分析了近2期流动重力资料,对2009年4月19日阿合奇发生的MS5.5地震和2009年4月22日阿图什发生的MS5.0地震进行了初步分析。结果表明,这两次地震的孕育与发生,都伴随着重力异常的出现,且地震发生在重力场变化的零线附近和重力场反向回跳的转折线附近。

| Abstract: | After calculating and analyzing mobile gravity data of two observation period, the author analyzed Aheqi Ms5.5 earthquake on April 19 and Atushi Ms5. 0 earthquake on April 22, 2009, preliminarily. The result showed that both the inoculation and occurrence of the two earthquakes went with the appearance of the gravity abnormality. Both the earthquakes occurred near the zero line of the gravity field change and the transition line of gravity field rebound reversely. |
