SEISMIC ANISOTROPY PARAMETERS OF TRANSVERSE WAVES BY GAJIGABUL EARTHQUAKE WHICH OCCURRED 10 FEBRUARY 2014 ML = 5,8

Abstract

In the article presents an analysis of the parameters of split shear waves from deep (h = 56 km) the earthquake occurred within the Lower Kura depression February 10, 2014 with Ml = 5,8. Spatial analysis of waveforms is conducted with use 3-component digital signal records. For selected areas of 3-component records in the program «DIMAS» construct a three-dimensional graph of the trajectory of particle motion and trajectory of the projection on the plane NE, NZ, EZ. Established the birefringence effect, ie, shear wave splits into two (S1 and S2), each of which has its polarization and the rate for broadband three component records (BHE, BHN, BHZ) of 4 seismic stations («QUB», «GAN», «LKR», «GOB»). This makes it possible to study small-scale deformations for a better understanding of dynamic processes and properties with depth media.
