| This fault was added in 2002 based on slip rates reported by Anderson and others (1995). They indicate this fault is characterized by rates on the order of 0.02 and 0.07 mm/yr (average 0.045 mm/yr). Subsequently, dePolo (1998) reported a preferred slip rate of 0.07 mm/yr, which was based on field data of Anderson and others (1995). |
