Rupture Variation Generator v5.2.3 Verification

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 (black) and v5.2.3 (blue) at 3, 5, and 10 sec, for SBSM and USC.

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.
