Abstract

Similarity of earthquakes is generally assumed for the prediction of strong ground motion for future large earthquakes. If earthquakes are similar, it is expected that short-period source spectral amplitude is proportional to one-third power of the seismic moment. Strong motion records at K-NET and KiK-net stations are analyzed and relationship between short-period source spectral amplitude and seismic moment is examined. Similarity is not found for the earthquakes analyzed here. Larger earthquakes radiate short-period seismic energy more effectively than smaller ones.
