苏联中亚地区包括五个加盟共和国(即土库曼、乌兹别克、塔吉克、吉尔吉斯和哈萨克)。该地区是苏联境内地震活动最强的地区之一。每年发生M_L≥3(k≥10)的地震七百多次,大部分为浅源地震。阿什哈巴德、塔什干、阿拉木图等一些大城市都曾遭受过强烈地震的破坏。因此,苏联在这一地区布设了大量的各类台网,投入了相当大的力量进行地震学基础理论、前兆和地震预报等多方面的实验研究工作,其研究水平在全苏具有代表性。 本文就苏联中亚地区地震观测系统的构成分布、仪器设备、监测能力及其未来发展动向做一概述。 一、观测系统的现状
The Central Asian region of the Soviet Union includes five republics (Turkmenistan, Uzbekistan, Tajikistan, Kyrgyzstan and Kazakhstan). The area is one of the most seismic areas in the Soviet Union. Each year more than 700 earthquakes with M_L≥3 (k≥10) occur, most of them are shallow earthquakes. Some large cities such as Ashgabat, Tashkent and Almaty have been devastated by a strong earthquake. Therefore, the Soviet Union has deployed a large number of various kinds of stations and networks in this area and devoted considerable efforts to carrying out experimental research on the basic theories of seismology, precursors and earthquake prediction. Its research level is representative in the whole of Jiangsu. This article gives an overview of the composition, equipment, monitoring capability and the future development trend of the seismic observation system in Central Asia of the Soviet Union. First, the status of the observing system
