A crustal deformation study of the Charlevoix seismic zone in Quebec.
Bibliographic record
Abstract
First order spirit levelling and high precision GPS measurements have been used to quantify local deformations caused mainly by postglacial rebound in the Charlevoix seismic zone, the region with the highest concentrated seismic activity in eastern Canada. In this paper, part of the Canadian first order vertical network, measured from 1909 to 1991, is analyzed for repeating levelling lines. In addition, a part of a first order geodetic network along the Saint Lawrence River surveyed by GPS in 1991 and 2005, is processed. The coordinate changes of these geodetic points allows for the determination of horizontal and vertical velocities leading to information about the crustal deformation of this region. The results show a southeast drift trend in the horizontal, and general uplift trend in the vertical. These agree well with previous GPS surveys conducted on Canadian Base Network (CBN) pillars in eastern Canada and with geophysical postglacial rebound (PGR) models.

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.
