The results of experiments to assess the possible influence on seismic safety of structures of seasonal changes in the natural frequencies of the underlying soils are given. It is shown that the resonance properties of the surface soil layer during the year can vary more significantly than the properties of the structures built on them. This can lead to the coincidence of natural frequencies of the soil layer and the structures standing on it, which ultimately reduces their seismic safety.
