摘要
利用中国和全球地震目录,着重研究中国地震活动在全球地震活动中的空间图像模式和中国37年来地震活动的时间进程。提出环太平洋地震带深入大陆内部的分支以及地中海-喜玛拉雅地震带的叠瓦状单元分布,指出中国地震活动无论处在高潮期或者稳态进程中的空间图像模式都是基本稳定的。还发现中国地震活动在两个高潮期之间存在一个长达19a的稳态进程。揭示了稳态进程的活动规律,指出了稳态进程在未来地震预报中的意义。
In this paper, we emphatically study the spatial image pattern of China earthquake activity contrast to the world earthquake activity and the time series of China earthquake activity in the last 37 years by China earthquake catalogue and world earthquake catalogue ANSS, point out that the spatial distribution of the inland branch of the pacific earthquake belt and the Mediterranean - Himalayas earthquake belt distribute in a form of tiled earthquake unit, and the spatial image pattern of the China earthquake activity is stable whenever it is in the high level period or the stable state period. It is found that there was a 19-year-long stable progress between two high level periods of China earthquake activity, and showed out the rule of the earthquake activity in the stable progress and the significance of the stable progress in earthquake predication in the furore. Finally, we draw a conclusion that it would widen our sight to regard the time characteristic and the spatial characteristic of China earthquake activity in a point of view of the world earthquake activity.
