STUDYING GLOBAL TECTONIC DISLOCATIONS FROM MEASUREMENTS OF CONTEMPORARY CRUSTAL MOVEMENT

The rates of contemporary vertical movements of the earth's crust, cal culated for the present epoch on the basis of high-precision leveling data, are presented as random functions of distance. Proceeding from t he wave geomechanics concept, the deterministic parts of the random fu nctions are presented as sums of different sine curves. With the help of a known spectral analysis technique, it is demonstrated on the exam ple of two leveling lines that it is possible to isolate standing rota tion waves with spatial periods of about and less than 120-degrees.
