Abstract
This Open File Report provides the available macroseismic information for the seven largest moderate earthquakes that occurred in the Charlevoix Seismic Zone between 1870 and 2021. These earthquakes and their moment magnitude (M) are: 1) February 3, 1902, M 4.5; 2) September 30, 1924, M 5.2; 3) January 08, 1931, M 4.9; 4) October 19, 1939, M 5.3; 5) October 14, 1952, M 4.5; 6) August 19, 1979, M 4.8; 7) March 6, 2005, M 4.7. Five, possibly six, of these seven earthquakes occurred in the northeast portion of the CSZ, where the largest event of the period, the 1925 M 6.2 earthquake, also occurred. For each locality where the earthquakes were felt, macroseismic information is given and interpreted on the Modified Mercalli Intensity Scale. The original mail questionnaires filled by postmasters for earthquakes no. 3, 4, 5 and 6 are lost. Consequently, the main sources of information are the newspaper accounts except for no. 7 for which web-based questionnaires are available. The macroseismic information from localities in Canada and in the US (from NOAA) are tabulated in Microsoft Excel spreadsheets. Most newspaper clippings that have macroseismic information are included. The Open File also provides Google Earth kmz files that allow the felt information reports to be viewed in 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.
How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
