説明
<jats:p> Convergence across the San Andreas fault (SAF) system is partitioned between strike-slip motion on the vertical SAF and oblique-slip motion on parallel dip-slip faults, as illustrated by the recent magnitude <jats:italic>M</jats:italic> <jats:sub>s</jats:sub> = 6.0 Palm Springs, <jats:italic>M</jats:italic> <jats:sub>s</jats:sub> = 6.7 Coalinga, and <jats:italic>M</jats:italic> <jats:sub>s</jats:sub> = 7.1 Loma Prieta earthquakes. If the partitioning of slip minimizes the work done against friction, the direction of slip during these recent earthquakes depends primarily on fault dip and indicates that the normal stress coefficient and frictional coefficient (μ) vary among the faults. Additionally, accounting for the active dip-slip faults reduces estimates of fault slip rates along the vertical trace of the SAF by about 50 percent in the Loma Prieta and 100 percent in the North Palm Springs segments. </jats:p>
