Development of an NEHRP map for the Orleans suburb of Ottawa, Ontario
Bibliographic record
Abstract
The average shear-wave velocity to a depth of 30 m (V s30 ) has been obtained for 73 sites in the Orleans area in the northeast part of the City of Ottawa. Measurements of V s30 were made using both ground surface reflection and refraction methods. In addition, borehole data was used to estimate V s versus depth profiles using average V s values assigned to distinct geological units. High values of V s (>1500 m/s) were obtained in areas of thin surficial sediments overlying Paleozoic bedrock, and low V s values (<180 m/s) were calculated in areas of thick late–post-glacial clay. The V s30 values have been used to prepare an NEHRP map for the study area. Much of the suburb of Orleans is classified as NEHRP zone E, whereas the perimeter areas and some isolated central areas are classified as zones ranging from zone D to zone A. The presence of thick unconsolidated late–post-glacial sediments deposited in the Champlain Sea is the main contributing factor to the wide range of average shear-wave velocities in the study area.

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.
