苏联的面积为二千二百四十万平方公里,人口约二亿六千二百万。有五分之一的土地处于地震区。百分之二十的居民深受地震灾害。苏联的地震大多集中在南部和东部,地震最强烈的地区是中亚。 据统计,全苏每年约发生十万次地震。每2～3年发生一次6.5级以上地震。近百年来,苏联境内共发生八次8级以上地震,五十余次7级以上地震。频繁的地震往往带来巨大的灾难。百年来尤以1948年阿什哈巴德7.3级地震损失为最。 为了减轻地震灾害,苏联地震工作者于四十年代末进行地震预报研究工作,六十年代以来,他们做了大量的工作,主要是建立了统一地震观测系统、地震实验场、进行室内模拟试验和理论研究、广泛进行国际合作等。本文试图对这些内容做一简介。
The Soviet Union covers an area of 22.4 million square kilometers and has a population of about 262 million. One-fifth of the land is in the earthquake zone. Twenty percent of residents are affected by the earthquake. Most of the Soviet Union earthquakes concentrated in the south and east, the strongest earthquake in Central Asia. According to statistics, about 100 thousand earthquakes occur in the whole province every year. Every 2 to 3 years, a magnitude 6.5 earthquake occurs. In the past century, there have been eight earthquakes of magnitude 8 or more in the Soviet Union and more than 50 earthquakes of magnitude 7 or above. Frequent earthquakes often bring about huge disasters. In a hundred years, the magnitude of the Ashkabad 7.3 earthquake hit the most in 1948. In order to alleviate the earthquake disaster, Soviet earthquake workers carried out earthquake prediction research work in the late 1940s. Since the 1960s, they have done a great deal of work, mainly establishing a unified seismic observation system, an earthquake experimental field, conducting indoor simulation tests and Theoretical research, extensive international cooperation and so on. This article attempts to make a brief introduction to these contents.
