The 1929 magnitude 7.2 Grand Banks earthquake: felt reports from the dominions of Canada and Newfoundland and islands of Saint-Pierre and Miquelon, France
Bibliographic record
Abstract
The 18 November 1929 Magnitude (M) 7.2 earthquake is the largest historical earthquake of eastern Canada. The earthquake was felt over most of Newfoundland and Labrador, at St-Pierre and Miquelon, in the Maritimes, eastern Quebec and New England. In this Open File Report, we include scans of the original felt information questionnaires that were received by the Dominion Observatory shortly after the earthquake occurred and other felt information from Canada, the Dominion of Newfoundland and St-Pierre and Miquelon. For each locality, the felt information is rated on the Modified Mercalli intensity (MMI) scale and tabulated in a Microsoft Excel sheet. Some 155 MMI reports are listed. This Open File is a pilot project that aims at evaluating the level of effort required to have all similar macroseismic information of Canadian earthquakes included in an intensity database. A total of about four weeks of work was necessary to produce this Open File Report.
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.
How this classification was reachedexpand
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.
