 This tests creates a downsampled UCERF3 forecast for southern california. Every rupture that is outside of Southern California (using the white dashed dividing line seen in the figure on the front of the [http://pubs.usgs.gov/fs/2015/3009/pdf/fs2015-3009.pdf UCERF3 Fact Sheet]) is removed. If a rupture is partially outside, it is removed and its rate is added to the largest subset rupture which is entirely inside the region. This results in 64992/253706 ruptures retained for UCERF3 Fault Model 3.1.

 The following figure shows the resulting MFD following this downsampling proceedure (blue curve). The original MFD (black curve) and MFD were we to just exclude partial ruptures rather than add their rate to subset ruptures (green curve) are also shown. Note that these are nucleation MFDs (as opposed to participation) and only include supra-seismogenic fault ruptures.

 We have produced a velocity mesh and applied smoothing on all the interfaces.  For smoothing, we have used a simple average of surrounding points.  Smoothing was performed up to 5 km from a model interface, and only in the X-Y plane.  For testing purposes, we have started with a mesh with 400 m spacing, and a minimum Vs=500 m/s.  Additionally, we extend the values at 45 km down to the 80 km depth.
