[地震扭结点] 两个或两个以上地震带在平面上的交汇点。由中国学者马宗晋于1982年正式提出。根据震源分布和地壳探测资料发现,地震扭结点处的地壳构造往往十分复杂,例如板块俯冲面呈现扭曲反转、对冲、双重俯冲等。在大陆上,地震扭结点是浅源和中、深源地震集中发生的场所。在亚欧地区目前已发现有七个地震扭结点,它们是藏东结点、帕米尔结点、阿曼湾东结点、土耳其中部结点、爱琴海结点、喀尔巴阡弧结点和西西里弧结点。类似的地震扭结点在西太平洋岛弧系的交点附近以及东太平洋许多海岭轴线与大陆相交的地方也有发现。
[Earthquake Kinks] Intersection of two or more seismic zones in a plane. By Chinese scholar MA Zong Jin formally proposed in 1982. According to the distribution of source and crustal exploration data, it is found that the crustal structure at the earthquake kinking point is often very complicated. For example, the subduction surface of the plate shows twisting and reversal, hedging and double subduction. On the mainland, the earthquake kink is the place where the shallow and middle-deep earthquakes occur intensively. Seven earthquake kinks have been discovered in Asia and Europe so far. They are the eastern Tibetan node, the Pamir node, the eastern Gulf of Oman, the central node of Turkey, the Aegean junction, the Carpathian node and Sicily arc node. Similar earthquake kinks have also been found near the intersection of arc systems in the Western Pacific Ocean and at the intersections of many ridge axes in the eastern Pacific with the mainland.
