Comments
Fault assigned 75 percent probability and represents rupture of the Carson Range and Kings-Canyon faults rupturing together as suggested by Ramelli and others (1999; pg. 1470). The assigned slip rate, based on Ramelli and others (1994), is inferred for the entire fault zone. Dip of fault changed to 50? based on redefined regional default value (Lund, 2006).
