Fig. 12

Residual standard deviations between the observations and the predictions for PGAs of S-waves against time-window lengths from P-waves arrival, for earthquakes of Mj 4 or larger and earthquakes of less than Mj 4, at the strong-motion stations. In the figure, standard deviation σ in logarithm is indicated. a Earthquakes of than Mj 4 or larger. b Earthquakes of less than Mj 4
