Foothill Sanitary Landfill – Seismic Characterization 4 03.18.2015 <br />3.8 Northern San Andreas (SAO+SAN+SAP+SAS) <br />The four segments that comprise the Northern San Andreas Fault zone were selected for this <br />seismic characterization: SAO - Offshore, SAN - North Coast, SAP - Peninsula, and SAS - Santa <br />Cruz Mountains. The Northern San Andreas Fault is a strike-slip fault, characterized by a total <br />fault length of 472.0 km, a fault plane width of approximately 11.8 km, and an unreported slip <br />rate (USGS, 2008). The Northern San Andreas Fault zone is approximately 133.0 km from the <br />Landfill site with a reported maximum moment magnitude earthquake of 8.05 (USGS, 2008). <br />The maximum moment magnitude of 8.05 has been selected as the MCE for this fault zone. <br />A summary of the eight fault / fault zones and their corresponding source parameters are <br />presented in Table 1 below. <br />Table 1 <br />Su mmar y of Fault / Fault Zo nes and Co rres po ndi ng Sou rce Paramet ers <br />Fau l t / Fau l t Zone <br />Name <br />MCE <br />Mo ment <br />Magn itud e <br />“Mw” <br />Sli p <br />Type <br />Fau l t <br />Length <br />Fault <br />Width <br />“W” <br />Slip <br />Rate <br />Dip / <br />Dir ecti o n <br />Cl os est Di stan ce <br />fr om <br />L an dfill Site <br />to Surface <br />Pro j ecti on of <br />Coseis m i c <br />Rup t ur e <br />“RJB”” (=RX) <br />Cl os est <br />Distance <br />fr om Lan d fil l <br />Site to <br />Coseis m i c <br />Rup t ur e <br />“RRUP” <br />Depth t o Top <br />of Co sei smic <br />Rup t ur e <br />“ZTOR” <br />Dept h t o <br />B ottom o f <br />Coseis m i c <br />Rup t ur e <br />“ZBOT” <br />Gr eat Val ley 7 <br />(Cen t ral Valley Coas t ) 6.90 thrust 59.3 km 11.6 km 1.5 mm/yr 15ž / W 59.33 km 59.74 km 7.0 km 10.0 km <br />Green vi lle 7.00 strike <br />slip 50 km 14.2 km 2.0 mm/yr 90ž / V 74.36 km 74.36 km 0.8 km 15.0 km <br />Mou nt Diablo 6.70 thrust 25.0 km 12.9 km 2.0 mm/yr 38ž / NE 84.55 km 76.0 km 8.0 km 16.0 km <br />Orgalit a 7.10 strike <br />slip 70 km 11.0 km 1.0 mm/yr 90ž / V 89.41 km 89.41 km 0.0 km 11.0 km <br />Green Valley 6.80 strike <br />slip 56 km 7.3 km 4.7 mm/yr 90ž / V 93.43 km 93.50 km 3.7 km 11.0 km <br />Cal veras <br />(CN+CC+CS) 7.03 strike <br />slip 123 km 4.8 km not avail. 90ž / V 94.56 km 94.89 km 2.2 km 7.0 km <br />Hayward / Rod g ers Creek <br />(RC+HN+HS) 7.33 strike <br />slip 150 km 8.8 km 9.0 mm/yr 90ž / V 102.50 km 102.51 km 1.2 km 10.0 km <br />N.
