- Аннотация: Microseisms are used for calculation of seismic intensity increment in seismic microzonation problem and assessing the resonance characteristics of soils (the Nakamura method) for critical facilities. Results of application of the method are presented: maps of seismic intensity increment in different spectral ranges and map of resonance frequencies by Nakamura method. The depth of the bedrock top is estimated based on the resonance frequency map using a priori information on the shear wave velocity. The zones of higher intensities are well consistent with the areas of increasing thickness of the layer overlying high-velocity bedrock.
