概要

• 論文の詳細を見る

• Strong motion records at K-NET and KiK-net stations for earthquakes which occurred in the mid Niigata area are analyzed to examine the relationship between the amplitude of the short-period source spectrum and the seismic moment. Large earthquakes radiate more short-period seismic energy per unit seismic moment than small ones, which suggests a deviation from the similarity of earthquake source. Appropriate correction for the deviation from the similarity should be made when we synthesize strong ground motion for future large earthquakes by the empirical Green's function method.
