In this article, we report the outcome of the blind predictions, compare the predictions to the measurements released after completion of ground‐response analysis, and discuss the ground‐response analysis residuals. The discrepancy between the measurements and predictions is minimized considering the sources of variability such as the determined shear‐wave velocity profiles, the determined modulus reduction and damping curves, the input motions, and the 2D basin effect. Even if the best model is used, the predictions still cannot match the measurements perfectly because of the inherent randomness of seismic motion. The input motions significantly influence the prediction result, followed by the shear‐wave velocity profiles, and the soil NL curves present slight effects. Although the valley is very flat, 2D effects still influence the wave propagation within the valley and results in the underestimation of the ground response by the 1D approach at short periods below the site period.
