讨论了1960年智利M_W9.5级地震的位置特点和发生年份特点。将此震与2004年印度尼西亚M_w9.0级地震作了对比,发现有类似之处,即它们的位置皆位于深海沟端部相对变浅的地段。另外,其附近早期的大震活动与这两次9级以上大震的发生年份有韵律性相关。
The location characteristics and year characteristics of M_W9.5 earthquake in Chile in 1960 are discussed. A comparison of this earthquake with the M_w9.0 Indonesia earthquake in 2004 reveals similarities, ie, their location is located in a relatively shallow section of the deep trench. In addition, the early large earthquakes in its vicinity have a rhythm correlation with the occurrence years of these two earthquakes of magnitude 9 or above.
