Plumbing the depths of the San Andreas Fault

J. Andres Chavarria, Peter E. Malin, Eylon Shalev, AGU

Seismic monitors at the San Andreas Fault Observatory at Depth project provide vertical seismic profiles. The authors analyzed these profiles to detect microearthquake waves and gain valuable insights into the fault line's structure. The ratio of primary to secondary waves observed within the fault indicates the likelihood of two faults intersecting at the exact location of the experiment. The ratios may also be caused by increasing fluid saturation, which could account for the study's findings and be correlated to creep distribution associated with the area.
