The Calaveras Fault hasg enerated several historical earthquakes over magnitude 5. The largest historical earthquake associated with the Calaveras fault was the magnitude 6.6 earthquake in 1911. The expected recurrence of earthquakes on the Calaveras Fault is shown in Figure 1. Using the long term slip -rates (Table 1), there is about a 1/3 chance of a magnitude 6.75 earthquake on the Northern Calaveras in the next 100 years. Since this is larger than the largest historical earthquake, the MPE is defined by this earthquake magnitude. The recommended MPE is a magnitude 6.75 at a distance of 85 km. Hayward Fault The Hayward Fault is located 96 km west of the site. The Hayward Fault is often divided into three segments: Rodgers Creek, northern, and southern segements. Combined the three segments have a total length of 151 km. The southern segment extends from Warm Springs to south of Mills College, a distance of about 53 km. The site is closest to the southern segment. Many large earthquakes have occurred on the Hayward Fault in the historical record. The largest historical earthquakes associated with the Hayward Fault are the two magnitude 6.8 earthquakes: 1836 and 1868. The expected recurrence of earthquakes on the Hayward Fault is shown in Figure 1. Using the long term slip -rates (Table 1), there is about a 1/3 chance of a magnitude 7.0 earthquake on the Hayward fault in the next 100 years. Since this is larger than the largest historical earthquake, the MPE is defined by this MPE earthquake magnitude. I recommend using an MPE of magnitude 7.0 at a distance of 96 km for the Hayward Fault. San Andreas Fault The San Andreas Fault is located approximately 126 km west of the site. This section of the San Andreas Fault is called the Peninsula segment. The San Andreas Fault is a predominately right -lateral strike -slip fault extending from Cape Mendocino to Mexico. The northern and southern sections of the fault are divided by the central creeping
