Physical Processes That Control Strong Ground Motion

摘要: This chapter reviews the main characteristics of strong earthquake ground motion and physical processes that control these motions. Strong motions are characterized by peak amplitudes their spectra. Empirical upper limits median values identified. The mathematical basis for a physics-based prediction is representation theorem, which shows how source models wave-propagation effects combine to generate properties described. major cataloged Models implement this approach successful in generating realistic synthetics with approximately correct amplitudes.
