West Shore Lake Oroville Lineament Geologic Investigation, Northern California
Bibliographic record
Abstract
The ML5.7 1975 Oroville earthquake seven years after construction of Oroville Dam resulted in recognition of Quaternary activity along the Cleveland Hill fault (CHF) and Swain Ravine fault zone (SRF), located west of the Foothills fault system. A 10-km-long, north-south oriented zone of topographic lineaments including scarps, benches, and saddles identified on lidar coincide with possible northward extension of the CHF on the West Shore of Lake Oroville (WSLO) north of Oroville Dam. The lineaments are parallel with north-south oriented regional bedrock fabric. Field reconnaissance and four fault trench exposures revealed a robust correlation between differential erosion in the Jurassic meta-volcanic bedrock and the linear features. The resulting stepped topography is accentuated by side-hill-benches formed by colluvium that infills areas between resistant bedrock zones. A clay-rich saprolitic unit (175 ka) exposed across a prominent lineament in a trench in Bear Meadow was not faulted, precluding a faulting origin and seismogenic activity for the lineament zone.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
