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 />Summary of Fault / Fault Zones and Corresponding Source Parameters <br />Fault / Fault Zone <br />Name <br />MCE <br />Moment <br />Magnitude <br />“Mw” <br />Slip <br />Type <br />Fault <br />Length <br />Fault <br />Width <br />“W” <br />Slip <br />Rate <br />Dip / <br />Direction <br />Closest Distance <br />from <br />Landfill Site <br />to Surface <br />Projection of <br />Coseismic <br />Rupture <br />“RJB” (=RX) <br />Closest <br />Distance <br />from Landfill <br />Site to <br />Coseismic <br />Rupture <br />“RRUP” <br />Depth to Top <br />of Coseismic <br />Rupture <br />“ZTOR” <br />Depth to <br />Bottom of <br />Coseismic <br />Rupture <br />“ZBOT” <br />Great Valley 7 <br />(Central Valley Coast) 6.90 thrust 59.3 km 11.6 km 1.5 mm/yr 15º / W 59.33 km 59.74 km 7.0 km 10.0 km <br />Greenville 7.00 strike <br />slip 50 km 14.2 km 2.0 mm/yr 90º / V 74.36 km 74.36 km 0.8 km 15.0 km <br />Mount Diablo 6.70 thrust 25.0 km 12.9 km 2.0 mm/yr 38º / NE 84.55 km 76.0 km 8.0 km 16.0 km <br />Orgalita 7.10 strike <br />slip 70 km 11.0 km 1.0 mm/yr 90º / 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 90º / V 93.43 km 93.50 km 3.7 km 11.0 km <br />Calveras <br />(CN+CC+CS) 7.03 strike <br />slip 123 km 4.8 km not avail. 90º / V 94.56 km 94.89 km 2.2 km 7.0 km <br />Hayward / Rodgers Creek <br />(RC+HN+HS) 7.33 strike <br />slip 150 km 8.8 km 9.0 mm/yr 90º / V 102.50 km 102.51 km 1.2 km 10.0 km <br />N.
