| 摘 要： | 断层的不稳定滑动(粘滑)被作为地震的一种机制提出后, 已普遍被人们接受, 文中对该机制所表现出来的断层异常活动的研究成果进行了分析和简述。给出了强震中短期阶段断层不稳定滑动过程中断层异常活动时空特征, 并从地球动力学的观点, 提出了明确的强震中短期阶段断层异常活动时空演化特征。 |
| 关 键 词： | 强震 中短期阶段 断层活动 时空演化特征 地球动力学 |

| Abstract: | After the unstable sliding (stick-slip) of fault was put forward as a mechanism of earthquakes, it has been universally accepted. In this paper, the research results of the mechanism of earthquakes show the anomaly activity of fault are analyzed and briefly described. The spatio-temporal characteristics of anomaly activity of fault is given on the unstable sliding of fault in the middle-short period of strong earthquakes, and the clear spatio-temporal evolutionary characteristics of anomaly activity of fault is raised in the middle-short period of strong earthquakes from the viewpoint of geodynamics. |
| Keywords: | Strong earthquake Middle-short period Activity of fault Spatio-temporal evolutionary characteristics Geodynamics |
