Abstract

fetched live from OpenAlex

The December 25, 1989, Moment Magnitude 6.2 Ungava, Quebec, earthquake is one of the largest northern Canadian earthquakes of the 20th century. It occurred in the middle of the Ungava peninsula of Quebec and caused the first documented earthquake surface rupture in Canada east of the Rockies. This Open File Report includes the macroseismic information on this earthquake, including felt report questionnaires. For each locality, the interpreted information is presented in a digital table. The fields include the name, latitude and longitude of the municipality, a short description of the felt effect and the interpreted intensity on the Modified Mercalli Intensity (MMI) scale. Finally, a GoogleEarth kmz file is added for viewing the felt information reports within a spatial tool.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
