Comparison between 1D predictions and recorded ground motions at KUMA for the Mj 6.5 earthquake and GoF evaluation following Kristeková et al. (2009). TF representation of the envelope (TFEG) agreement between 1D EQL predictions and recorded ground motions with the evaluation of envelope GoF along time (TEG) and frequency (FEG) axes (a and b upper panels). TF representation of the phase (TFPG) agreement between 1D EQL predictions and recorded ground motions with the evaluation of phase GoF along time (TPG) and frequency (FPG) axes (a and b lower panels). Overall integral GoF metrics for the envelope (EG) and phase (PG) agreement are reported in the black box with values in the range 0–10, where 10 means perfect agreement. Left panels show TFEG and TFPG for the EW component of predicted (black line in middle panel) and recorded (red line in middle panel) ground motions; right panels show the same quantities for the NS components. c and d Show the same quantities and information as in a and b but for the 1D NL approach
