Duration of strong ground motion
WebDec 28, 2024 · The distance after which the duration of ground motions for small magnitude events saturate is ∼60 km for shallow crustal earthquakes and ∼200 km for subduction earthquakes. Another difference between shallow crustal earthquakes and subduction earthquakes is the slope of duration versus distance. WebThe database includes time series and pseudo-spectral acceleration (PSA) for the 5%-damped elastic oscillators with periods ranging from 0.01 to 10 sec. Additionally, the …
