The slip rate estimates for the CRCV fault system also has a large uncertainty. Recent <br />estimates of the slip -rate range from 0.5 mm/yr to 3.0 mm/yr. The CDMG (1996) used <br />a slip -rate of 1.5 mm/yr and that value is used in this study. <br />The maximum historical earthquake controls the MPE for the CRCV. For this study, I <br />recommend using a magnitude 6.5 at a rupture distance of 62 km for the MPE for the <br />CRCV fault zone. <br />Greenville -Marsh Creek -Arroyo_ Fault <br />The Greenville fault is part of the Greenville -Marsh Creek -Arroyo fault system has <br />primarily strike -slip motions and extends for a total length of 73 km. The Greenville - <br />March Creek segment is located 76 km west of the site. The largest historical <br />earthquake for this fault system was the 1980 magnitude 5.8 earthquake that occurred <br />on the Greenville -March Creek segment. <br />Using the long term slip -rates (see Table 1), there is about a 1/3 chance of a magnitude <br />6.3 earthquake on the Greenville -Marsh Creek -Arroyo fault in the next 100 years (see <br />Figure 1). Since this larger than the maximum historical earthquake for this fault, the <br />MPE is defined by the magnitude 6.3 earthquake. <br />I recommended using a magnitude 6.3 earthquake at a distance of 62 km for the MPE <br />for the Greenville -Marsh Creek -Arroyo fault. <br />Calaveras Fault <br />The Calaveras Fault is located 96 km west of the site. The total fault length of the fault <br />is approximately 120 km, however, it is often segmented into northern and southern <br />segments. The southern segment, 76 km long, extends from Hollister to the Calaveras <br />Reservoir. The northern segment, 52 km long, extends from north of the Calaveras <br />Reservoir to Danville. The site is closest to the northern segment. <br />The Calaveras Fault has generated several historical earthquakes over magnitude 5. <br />The largest historical earthquake associated with the Calaveras fault was the magnitude <br />6.6 earthquake in 1911. <br />The expected recurrence of earthquakes on the Calaveras Fault is shown in Figure 1. <br />Using the long term slip -rates (Table 1), there is about a 1/3 chance of a magnitude 6.6 <br />
