Instrumental Seismic Observations in the Caucasus in the First Half of the 20th Century
摘要
The article is dedicated to the history of development of instrumental seismic observations in the Caucasus in the first half of the 20th century. The stages of seismic observation development in the Caucasus are described, including the problems that arose during World War I and the Civil War, as well as the subsequent restoration of the seismic service in the USSR. The information on the first seismic stations in the Caucasus, their equipment, and their role in studying the seismicity of the region is summarized. Maps of the theoretical recording range of earthquakes of various magnitudes by seismic stations in the Caucasus for different periods are presented. Seismic stations of the first half of the 20th century made it possible to obtain the first data on the seismicity of the region, which made an important contribution to the study of the seismic hazard of the Caucasus region and ensuring earthquake-resistant construction on its territory; to research into the causes and conditions of earthquakes in the Caucasus with the aim of finding precursors of destructive earthquakes; and to the study of the internal structure of the region.
