Abstract
Along with source effects and path effects, local site effects are among the main factors defining parameters of strong motion. The effects of soil response during strong earthquakes have always received considerable attention in seismology, because most urbanized areas are located in river valleys, on soft sediments. Large cities, such as, Tokyo, Osaka, Kobe, Los Angeles, San Francisco, San Salvador, Caracas, Lima, Bogota, Kathmandu, Manila, Thessaloniki, Mexico city, and others are located in river valleys in seismic areas. The prevalence and significance of these effects stimulated numerous instrumental, theoretical, and numerical studies aimed at better understanding and quantifying of the effects. To date, seismology has developed methods for reliable evaluation of these effects.
