1933年8月25日15时30分,四川叠溪发生了震源深度仅为6.1千米的7.5级大地震,滔滔岷江因之断流,千年古镇因之湮没,近万生灵因之遇难。近日,笔者有幸拜读了地质学家常隆庆“去大震之日未远”([1])~亲历震区调查后所著的《四川叠溪地震调查记》(下称《调查记》),既为常先生之科学精神所折服,也为《调查记》之科学成就所震撼。谨以此文,献给这位伟大的中国地震科学先行者。行者常隆庆常隆庆(1905-1979),字兆宁,四川江安人,著名地质学家,著有《重庆南川间地质志》《四川叠溪地震调查记》《宁属七县地质矿产》《中国地质学》等20多部著作。
At 15:30 on August 25, 1933, an earthquake of magnitude 7.5 occurred at Diexi, Sichuan, with a focal depth of only 6.1 km. Due to the continuous flow of the Minjiang River and the annihilation of the ancient town, thousands of souls were killed. Recently, I have the honor to read the geologist Chang Longqing “go far to the day of the earthquake ” ([1]) ~ after the earthquake survey conducted by the “Sichuan Diexi earthquake investigation” (hereinafter referred to as “survey” ), Which is not only impressed by the scientific spirit of Mr. Chang, but also shocked by the scientific achievements of the “survey”. I would like to dedicate this article to this great forerunner of earth science in China. Walker often Longqing Chang Longqing (1905-1979), the word trillion, Sichuan Province, the famous geologist, author of “Chongqing Nanchuan Geological”, “Sichuan Diexi earthquake investigation” “Ningxian seven counties geology and mineral” “China Geology” and more than 20 books.
