Comparison of small events for USC

Below is a comparison of source 145, rupture 2 (M6.15) for USC, with G&P 2014 and 2015.

Seismogram plot:

Seismogram USC s145 r2 rv7 4681v4685.png

PSA plot:

PeakVals USC s145 r2 rv7 4681v4685.png

The two SRFs are available here (G&P 2014, v3.3.1) and here (G&P 2015, v5.2.3).


Below is a comparison of source 143, rupture 2 (M6.15) for USC, with G&P 2014 and 2015.

Seismogram plot:

Seismogram USC s143 r2 rv7 4681v4685.png

PSA plot:

PeakVals USC s143 r2 rv7 4681v4685.png

The two SRFs are available here (G&P 2014, v3.3.1) and here (G&P 2015, v5.2.3).

Comparison of source 115, rupture 6

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).

Plot of v3.3.1 realization
Plot of v5.2.3 realization

A plot comparing the generated seismograms for both versions:

Plot comparing seismograms for src=115, rup=6, rup var=138, for v3.3.1 and v5.2.3.


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):
