CCA N SAF Tests
Sites in the Northwest part of the CCA model region are within 200km of UCERF2 N. San Andreas events, while those in the Southeast are further away. Therefore, only some sites in the CCA model include N. SAF events with the default 200km cutoff distance. We wish to explore the affect of this cutoff distance by computing hazard curves at sites which are just under 200 KM from the N. SAF both with and without those events.
The gray dashed line in all plots highlights the 2% in 50 year level.

Parkfield
The CyberShake Parkfield site is ~138 km from the N. SAF in UCERF2 with Z2.5=3.28km in the CCA 3-D model. These were done with the wrong impulse.

s1207
The CyberShake s1207 site is ~198 km from the N. SAF in UCERF2 with Z2.5=8.34km in the CCA 3-D model. This includes the correct impulse, and the USGS Bay Area model in northern CA.
