HIGH-FREQUENCY SOURCE SPECTRAL RATIO BETWEEN LARGE AND SMALL EARTHQUAKES
|

| 抄録（英）： |
Source spectral ratio between large and small earthquakes is investigated by analyzing spectral ratios of accelerograms at the same site for earthquakes with nearly the same hypocenter. The level of high-frequency spectral ratio between large and small earthquakes is larger than that expected from the ω■■ model with a constant stress drop. The deviation of the spectral ratio from the ω■■ model becomes large with increasing in magnitude difference between the earthquakes. The shape of the spectral ratio suggests that a two-corner model may be more appropriate for the source spectral model than a one-corner model such as the ω■■ model.
