SEISMIC CHARACTERISTICS OF SITES FOR IMS STATIONS IN RUSSIA. A RETROSPECTIVE

Abstract

In recent decades, seismic observations have been actively expanding all over the world. They are used in a very wide range of tasks: from studying mega-earthquakes over vast areas of subduction zones to assessing local micro-earthquakes in the area of an individual mine or recording weak events accompanying hydrocarbon extraction. More and more temporary and permanent seismic systems are appearing in Russia to monitor nuclear industry facilities and control man-made seismicity in mining areas. The article describes the work that was carried out at the turn of the century during the selection of locations for seismic stations, which later became part of the International Monitoring System (IMS) organized to control nuclear tests. The main principles and algorithms for selecting locations for seismic stations are considered based on the analysis of the experience of work on selecting sites for IMS stations in Russia; some seismic characteristics of the sites are given. A step-by-step analysis of the basic approaches used in the organization of the IMS seismic network may be useful in creating new observation systems to solve various problems.
