The Mw 7.9 Denali Fault Earthquake of 3 November 2002: Felt Reports and Unusual Effects across Western Canada
Bibliographic record
Abstract
The 3 November 2002 M w 7.9 Denali fault earthquake was one of the largest North American earthquakes of the past 100 years. This earthquake, located 330 km to the west of the Yukon-Alaska border, generated 260 reports of shaking and other “unusual effects” to distances of 3500 km across western Canada. Felt intensity for this earthquake ranged from V at communities in the Yukon closest to the epicenter (about 350 km distance), IV across much of the Yukon Territory (distances of 350 to 750 km), III across much of northern British Columbia, to II in southern British Columbia and Alberta (about 2400 km distance). In many instances, people reported feeling nauseous or seasick and having trouble standing. The long-period ground motions generated by this earthquake (displacements greater than ±10 cm were recorded in the Yukon) caused water to spill from swimming pools, generated seiches in lakes and rivers, and affected wells (instances of dirty well water) to distances of 3500 km across western Canada.

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.
