Modern methods, techniques and technical means of monitoring movements of the Earth crust

Abstract

This article gives an overview of available methods and techniques for geodynamic monitoring, such as the high-precision geometric re-leveling, high-precision linear-angular constructions, high-precision distance measurements, laser scanning, global navigation satellite systems, laser interferometers and strainmeters, radar satellite interferometry. The experience of applying these technologies in different physiographic regions is also described. The tools used in measurements, which provide the maximum achievable accuracy of methods in modern conditions, are demonstrated. A table is made with the summary characteristic of instrumental methods to measure the parameters of current movements of the Earth crust. On the basis of the performed comparative analysis of modern methods, techniques and technical means for execution of geodynamic monitoring, the most effective ones have been chosen from the methods listed above. Such methods include methods of high-precision geometric levelling of I and II classes, as well as the global navigation satellite systems. Complex use of these methods will allow to obtain reliable data about the geodynamic situation of the investigated area.
