Abstract <p>The article reviews and summarizes the results of various computational and analytical studies of the seismic (topographic) effect of canyons of different shapes. It is noted that the shape and structure of canyon valleys have a significant effect on the amplitude and frequency characteristics of vibrations of the bottom, walls, and ridges of canyons during seismic wave of different incidence. Based on the published results of various authors on computational modeling of the canyon effect, numerous features of wave fields and effects of amplification and attenuation of seismic vibrations in canyons are shown. The importance of taking into account the results of computational and analytical studies to ensure the seismic-resistant design of construction projects located in and near canyons in seismic zones is emphasized.</p>
