Correlation between deep fluids, tremor and creep along the central San Andreas fault

  title={Correlation between deep fluids, tremor and creep along the central San Andreas fault},
  author={Michael Becken and Oliver Ritter and Paul A. Bedrosian and Ute Weckmann},
The seismicity pattern along the San Andreas fault near Parkfield and Cholame, California, varies distinctly over a length of only fifty kilometres. Within the brittle crust, the presence of frictionally weak minerals, fault-weakening high fluid pressures and chemical weakening are considered possible causes of an anomalously weak fault northwest of Parkfield. Non-volcanic tremor from lower-crustal and upper-mantle depths is most pronounced about thirty kilometres southeast of Parkfield and is… CONTINUE READING
