摘要： 初步分析了中国中部南北地震带历史大震活动在不同时间尺度的整体转移图像。 南北地震带近500年来地震活动东侧强于西侧地区; 本世纪以来大震(M≥7.1)活动的主体地区呈现自北向南的整体转移过程; 本活跃期以来强震(M≥6.0)的集中区明显西移。 据此, 对该带大震趋势及危险地区进行了分析和讨论。

关键词: 地震预测, 南北地震带, 大震转移图像

Abstract: In this paper, we analyzed the entire transferring picture of large earthquakes on the South-North earthquake belt in the middle of China with different time scale. In recent 500 years, the activity of large earthquakes is more intense along the eastern segment of the belt than the western one. Since this century there appear an transferring picture from north to south of the main area of the large earthquakes (M≥7.1). The principal area of earthquakes (M≥6.0) is turning to western segment since this active period. Hereby, we analyzed the trend of the large earthquakes and the risk area on this belt.

Key words: Earthquake prediction, Entire transferring, North-South earthquake belt, Transferring picture of large earthquakes
