COMPLEX ANALYSIS OF THE SIGNAL OF THE EARTH-S CRUST STRAIN METER IN THE BAIKAL RIFT ZONE
Abstract
From 1994 to the present, records of deformations of the Earth?s crust, which are measured by a laser displacement meter, called ?deformograph?, are regularly recorded. This meter records changes in the distance between the mirrors fixed on the rock inside the mountain gallery in two directions: North-South and West-East. Such observations are carried out in the Gorny Altai region, in Kazakhstan and near Lake Baikal. One of the long-acting deformographs is installed in the gallery of the Talaya seismic station in the Baikal Rift Zone (BRZ). Records of deformations (deformograms) are analyzed to study the processes in the Earth's crust and to identify the forerunner of earthquakes. The work was done on systematization of digital records of the deformation process for the period from 1994 till now. A digital catalog has been compiled giving a general idea of the material available for processing. Records are analyzed in detail. The analisys of the signal is very important for the choice of the noise filtering method and other decisions for the accurasy increasing and informative significansy of the collected data. This paper reports the most interesting results of this analysis.
