Fifth generation seismic hazard model for Canada: grid values of mean hazard to be used with the 2015 National Building Code of Canada
Bibliographic record
Abstract
Canada's 5th Generation seismic hazard model is the basis for the seismic design provisions in the 2015 National Building Code of Canada. The 2015 code uses mean ground motion on firm soil sites for a probability of exceedance of 2% in 50 years, with the ground motion being described by seismic hazard values for eight parameters: spectral acceleration at 0.2, 0.5, 1.0, 2.0, 5.0 and 10.0 second periods, peak acceleration and peak velocity. We tabulate values of the eight parameters and for three additional spectral periods (0.05, 0.1 and 0.3 seconds) for more than 200,000 grid points over Canadian territory and surrounding areas. Values at eight probability levels are provided. The spectral parameters will allow the construction of approximate uniform hazard spectra and hazard curves for every locality in Canada, and hence provide necessary information for earthquake-resistant design.

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; a candidate call from one teacher head, not a consensus.
