Abstract

fetched live from OpenAlex

Fluids may play a significant role in the earthquake rupture process. Since fluids can dramatically change the electrical resistivity of crustal rocks, electromagnetic exploration methods can image in situ fault‐zone fluids. Magnetotelluric (MT) data has been collected on segments of the San Andreas Fault (SAF) in Central California exhibiting a range of seismic behavior from locked to creeping. This paper describes MT data from the creeping segment of the SAF near Hollister, California. Inversion models image a zone of enhanced conductivity beneath the surface trace of the SAF that has similar geometry and greater depth extent than the fault zone conductor at Parkfield. Comparison with geologic and seismic tomographic studies show this zone is bounded by the San Andreas and Calaveras Faults, and coincident with a zone of low seismic P‐wave velocities. Combined with previous MT studies, this indicates a correlation between seismicity and the presence of fault‐zone fluids.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
