分析了几个区域的地震间隙图像特征及其与地震大形势的关系.本世纪60年代前全球经历了大震活跃期,地震间隙基本保持平稳均匀分布,之后活动减弱、转平静,间隙高值的出现、显著的增大趋势和图像分散、分段成组性突出为相应的主要特点,全球及大区地震间隙高值有近20 a 的间隔优势.各种级别的地震活动都可作为高一级地震活动的震情“窗口”.最后简要分析了今后几年的地震趋势.
The characteristics of the image of the seismic gap in several regions and its relationship with the general situation of the earthquake are analyzed.At the 60th century of this century, the whole world experienced an active phase of large earthquakes, and the earthquakes remained basically stable and evenly distributed. Then the activity was weakened, tranquilized and the gap height was high , Significant increase in trend and image dispersion, subdivision grouping prominent for the corresponding main features, the global and regional seismic gap high value of nearly 20 a interval advantage of various levels of seismic activity can be used as high A seismic activity earthquake “window ” Finally, a brief analysis of the earthquake trends in the next few years.
