SPATIL VARIATION OF EARTHQUAKE GROUND MOTION BASED ON THE CHIBA ARRAY RECORDS
|
抄録（英）：
The spatial variation of earthquake ground motion is examined in terms of the coherence function based on eight earthquake events observed at the Chiba array. The events range in JMA magnitude from 4.8 to 6.7. Considering a preliminary analysis and previous works about coherence function, a Gaussian coherence function model is proposed for space-time earthquake ground motion assuming its limited portion to he homogeneous and stationary. Model parameters for S-wave portion are estimated by nonlinear regression analysis, and average and variance are evaluated for the regression coefficients obtained from each event. Finally, frequency-dependent correlation scale derived from the model is discussed.
