Abstract
ABSTRACT We document the paleoseismology of the Long Valley Fault, Central Otago, New Zealand. A single trench excavated across the 21 km long, northeast‐striking reverse fault reveals evidence for three ground‐rupturing earthquakes. Optically Stimulated Luminescence dates (including OxCal analysis) of displaced sedimentary units are used to constrain the timings of these events. The antepenultimate event is constrained at 74.4 ka (81.4–67.6 ka, 95% confidence interval), the penultimate event at 37.4 (55.2–19.1) ka, and the most recent event at 10.5 (14.3–6.7) ka. These events show a total of 5 ± 0.2 m of dip slip in the trench, with a range of 1–2 m displacement per event. The estimated magnitude and mean recurrence interval for the Long Valley Fault are Mw 6.9 ‐ 7.0 and 32.0 ± 12.3 kyrs, respectively. The study contributes to the growing Otago paleoseismic database, which will eventually be used to understand regional space–time deformation behaviours in transpressional tectonic environments.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
