Abstract

The paper studies the influence of the environment (site effect Station) in the path of the ray during propagation of seismic shear-wave from strong earthquakes. It was calculated the station corrections for earthquakes with a magnitude above 5 occurred in 2012-2015 yy using the method of Nakamura. On the basis of the averaged data for each station was built dimensional distribution map of amplification factor for Azerbaijan. The total value of the factor varies within 1,5-3,6. The maximum number observed in the zone of the Kura depression and Zakatala region, indicating that the layer of the earth’s crust under the stations of the region to strengthen exposure the shear wave for source-receiver.
