 The source zone was defined by Jessica Thompson Jobe, based on recent work by
 Price et al. (2019) and Ward et al. (2017).
 
-The zone is modeled with vertical strike-slip faults parallel to the southeast/northwest axis of the
-zone polygon (i.e., strike = 350 degrees).
+The zone is modeled with vertical strike-slip faults parallel to the southeast/northwest
+axis of the zone polygon (i.e., strike = 350 degrees).
 
 The Mmax distribution was informed by Price et al. (2019) and Ward et al. (2017).
 
 The total rate in the zone was based on estimated slip rates from Price et al. (2019)
-and Ward et al. (2017). The published slip rate (0.06 cm/yr) was cut in half (0.03 cm/yr) because we
-assumed half the slip could be on the other NMSZ faults. The source has also not been active for
-9000 years.

-For the 2023 NSHM, we give this source a weight of 0.5.
+For the zone rate, we use the weighted average of the above rates for all magnitudes.

+In the 2023 NSHM, we assign this source a weight of 0.5 with the `null` branch of the
+logic tree representing the possibility that nothing happens. The rates in this zone
+are not scaled with latitude.
