CyberShake/GMPE Combined Weights

The average spectrum (green lines in the above plots) represent a weighted average of CyberShake and the GMPEs. The weights are period dependent as shown below. Probabilistic results are averaged at the hazard curve level prior to calculation of the Risk Targeted Ground Motion value and deterministic results are averaged after deterministic calculation.
