The walls of several paleochannels, downcut into sensitive marine clayey silts, are scarred by numerous large earthflows of sizes unequaled in historical time. While radiocarbon ages of 15 landslides, as much as 35 km apart, range from ca. 1870 to 5130 yr B.P., the majority of events cluster at ca. 4550 yr B.P. The coincidence of numerous large failures in different paleovalleys, occurring concurrently, long after channel abandonment and at a time of drier climate, suggests that the widespread landsliding was triggered by a strong earthquake. Close to the landslide area, areas of very disturbed terrain in a flat erosional plain show severely deformed bedding and irregular ground subsidence and are attributed to a large earthquake, ca. 7060 yr B.P., that strongly shook a thick sequence of sensitive material filling deep, steep-sided, bedrock basins.

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
