Abstract
This chapter discusses the origin of the Farallon Plate that forms the basis for the Cascadia Subduction Zone (CSZ) along the Pacific Northwest Coastline. The Farallon Plate begun sinking into the mantel until it was beneath the North American Plate where it then scraped along the bottom of the continent for 1500 km before sinking again. The Farallon Plate acted as a conveyor belt, conveying terranes as it moved eastward. If the chunk of crust is small such as an island arc, it gets attached to the continental margin in a process called accretion. Much of the current geography of the U.S. West Coast is due to this process. The western boundary of this plate system due to ridges that are offset by transform faults gives an uneven appearance. These transform faults divide the Juan de Fuca plate into three distinct geographic regions: (1) Gorda (in the south), (2) Juan de Fuca (the central and largest region), (3) and the Explorer (the smallest segment offshore of Canada). The central or Juan de Fuca region is offshore of Oregon and Washington. These plate segments subduct beneath the North American Plate to form the CSZ fault. The plates deform elastically during subduction which causes vertical land-level change when the fault is seismogenically locked. Areas landward of the locked region of the fault generally uplift during the interseismic period. Areas directly above the formally locked region of the fault after a seismic event generally subside during the interseismic period. This vertical movement of the land whether upward or downward in addition to the eustatic rise in sea level results in a changing relative sea level along the northwest shoreline. This changing relative sea level along the shoreline results in potential erosion and cliff retreat. In addition to the above, the chapter discusses the nature and features of the coastline that control shoreline erosion.

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.
