This page details the verification work with the Graves & Pitarka (2015) rupture variation generator, v5.2.3, as compared to the Graves & Pitarka (2014) rupture variation generator, v3.3.1.

Hazard Curves

Below are hazard curves for a 0.5 Hz CyberShake run, comparing v3.3.1 and v5.2.3 at 3, 5, and 10 sec, for SBSM and USC.

GMPE Scatter Plots

Below are GMPE scatter plots for v3.3.1 (G&P 2014) and v5.2.3 (G&P 2015) runs, for SBSM and USC at 3, 5, and 10 sec.

Individual Source Comparison

To dig in deeper, I selected a single event (source 115, rupture 6, rupture variation 138).

Below are v3.3.1 and v5.2.3 plots for this event.
