The seismic rigidity method, which is one of the first instrumental methods of assessing the influence of soil properties on the parameters of seismic impacts, is currently experiencing contradictory to his attitude. On the one hand, this is the most commonly used method of seismic microzoning (SMZ), on the other hand it is hardly possible to find in SMZ another method that invokes such hard and various criticism. It should to note that these criticisms are not captured in the form of printed articles, but it is constantly occurs in various discussions, private views, etc. that only complicates public discussion. What here is true and must be take into account, and that should to reject? This article is the attempt to understand these interesting and practically important issues.
