In the article is carried out the analysis of practical-scientific works on seismic microzoning (SMZ). In spite of a change in the level of seismic danger from the time of their conducting [Building Codes II-7-81, 1982, 2000], the urgency of results did not decrease. The special action features of powerful nonexplosive sources, we have examined in a number of works, were used with SMZ of territories of Rustavi (1982), Gori (1983), Tkibuli (1985), Tbilisi (1989), Kutaisi (1990), etc.

With SMZ of Rustavi and Gori territories were used the surface pulse gas-dynamic source SI-32; with SMZ of Tkibuli territory — seismic vibrator SV-10/100; with SMZ of Tbilisi (1989), Kutaisi (1990) territories and individual sections of Big Sochi (1991) — seismic vibrator SV-10/100. With SMZ of Tbilisi and Big Sochi is for the first time used the simplified method, which helps to compose the vibration spectra (quasi-spectra) of the fluctuations of soils. With SMZ of Kutaisi territory (1996) is for the first time made the attempt to consider the nonlinearity of the soils of territory with the use of a seismic vibrator. The obtained results became the basis of the development of the new SMZ methods, which later were used for the estimation of the seismic danger of the territories of the areas of acting and projected Novovoronezh APS (1997).
