2001年昆仑山口西8.1级地震与1927年古浪8.0级地震的相似性

Similarities between 2001 West Kunlunshan Pass M8.1 and 1927 Gulang M8.0 E arthquake

对20世纪中国大陆巨大地震进行了研究,认为1927年古浪8 0级地震与2001年昆仑山口西8 1级地震在构造上,与川滇地区的相对位置上,以及孕育、发展和发生的过程都具有一定的相似性,这2个地震对其后川滇地区地震活动形势的影响也具有相似性;这2次地震的发生对中国大陆的地震活动强度有一定的缓解作用;2003年至2005年川滇地区地震活动水平为6 0～6 9级。

In this paper,the huge earthquakes of 20th century in China's Mainland were studied.The result shows that 2001 West Kunlunshan pass M8.1 and 1927 Gulang M8.0 Earthquake are similar in tectonics,the distances and directions from Sichuan-Yunnan Region,and their occurrence progresses.Also,those 2 earthquakes' affects on Sichuan-Yunnan Region's earthquake activity are similar.West Kunlunshan Pass M8.1 and Gulang M8.0 Earthquake's occurrences have effect on deducing China's Mainland's eatrhquake activity.Finally,the earthquake activity level in Sichuan-Yunnan Region during 2003 to 2005 was estimated as M6.0～6.9.
