Southern San Andreas Fault

Southern San Andreas Fault. Quiescence period: 300+ years Slip rate: from 10 to 35 mm/yr Observed creep episodes. How pervasive is creep on the southern SAF? What fraction of the elastic strain energy does it relieve?

  1. Southern San Andreas Fault Quiescence period: 300+ years Slip rate: from 10 to 35 mm/yr Observed creep episodes

  2. How pervasive is creep on the southern SAF? • What fraction of the elastic strain energy does it relieve? • What is the effective rate at which elastic strain accumulates on the southern SAF?
