Need for an Objective Goodness-of-Fit Measure for: Broadband synthetic time histories from different methodologies Broadband synthetic time histories versus strong-motion data

Kim B. Olsen and John E. Mayhew: Goodness-of-fit Criteria for Broadband Synthetic Seismograms, with Application to the 2008 Mw 5.4 Chino Hills, Califonia, Earthquake, Seismological Research Letters 80(6):

Time-domain Metrics: 1. Cross-Correlation (Waveform Comparison) 2. Peak Acceleration (PGA) 3. Peak Velocity (PGV) 4. Peak Displacement (PGD) 5. Cumulative Energy Spectral Metrics: 1. Smoothed Fourier Amplitude Amplitudes 2. Average Response Spectra (0.1-10s) 3. Spectral Accelerations at NGA Periods 4. Duration at Selected Periods 5. Inelastic/Elastic Ratios (I/E)

The Goodness-of-fit Scale Try Again

Visual Confirmation of GOF Values GOF FS =51GOF FS =11 GOF RS =75GOF RS =14 GOF PGV =82 GOF PGV =19

Redundancy of Metrics Correlation Matrix (33 stations)

User supplies a list of weights (w i ) Normalized weights are applied to each metric GOF value (  i ) for the overall site and component GOF values Weights

Example of GOF Estimation for M w 5.4 Chino Hills
