On older Earthquake Fault Zone maps, the zone boundaries are straight-line segments defined by turning points.The most significant faults within the plate boundary in central and northern California include the San Andreas, San Gregorio-Hosgri, and Hayward-Rodgers Creek fault zones. Each of these fault zones has important offshore sections that, until recently, were not mapped in great detail.

Subduction ended when the ancient Farallon Plate was overrun as North America moved westward, overriding the northern end of the spreading center in the Eastern Pacific basin (Figure 7.62).

The Pacific Northwest is home to the Cascadia Subduction Zone, a 1,300 km-long tectonic boundary between the Juan de Fuca and Gorda oceanic plates to the west and the North America continental plate to the east (Fig. 1). The denser oceanic plates are converging with North America and subducting beneath the western edge of the continent.

Along the northern California coast and offshore, Gorda-North American plate convergence is reflected by youthful west- to northwest-verging thrust fault systems that extend to or near the plate interface at depth. Interplate coupling across a minimum breadth of 70--80 km is indicated by late Quaternary uplift and shortening rates, the nature ...
