View source for 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.  Note that even though both events have shypo=27.0, dhypo=12.5, the v3.3.1 hypocenter is at (-116.37060, 33.33710, 2.78240) while the v5.2.3 hypocenter is at (-116.43904, 33.39450, 9.38238).

A plot comparing the generated seismograms for both versions:

|}


We repeated this for the two rupture variations which most closely match hypocenters, v3.3.1 rupture variation 172 and v5.2.3 rupture variation 117 (hypocenters ~0.2 km apart):
