文中利用可公度法对意大利地震灾害的时间对称性及趋势进行判断,旨在提高灾害趋势的判断水平,也为探索对称性结构物理机理提供一些基础认识。根据1948年以来意大利Ms≥6地震资料,应用可公度趋势判断方法,通过三元、四元、五元可公度计算及蝴蝶结构图分析,对意大利地震灾害的时间对称性及趋势进行了判断。结果表明:2014年意大利发生Ms≥6地震的信号最强。通过震中迁移分析,意大利地震震中主要分布在二、四象限,呈现东北-西南向对称。未来地震震中可能向东南方向迁移,发生在42°N以南,12°E以东,即意大利东南部的可能性较大。
This research used commensurability method to analyze the earthquake time symmetry and trend judgement in Italy, in Italy aiming to improve the level of disaster trend judgment, also provide some basic physi- cal mechanism for exploring symmetry structure. Based on the seismic data ( Ms ≥ 6 ) of Italy since 1948, the symmetry and tendency of the earthquake disasters in Italy were analyzed and judged by the methods of commen- surability information extraction and map of butterfly structure. The result showed that the earthquake( Ms ≥16 ) will occur in 2013 and 2014,future earthquakes with Ms≥6 location is east of 12°E and south of 34°N.
