Abstract
The November 18, 1929, M 7.2 Grand Banks earthquake occurred in the Laurentian Channel near the crest of the continental slope off the eastern coast of Canada. This seismic event, followed by a tsunamigenic landslide, is the largest instrumentally recorded earthquake that has occurred in the region. The event led to 28 confirmed casualties and significant destruction of critical commercial infrastructure and operations, including trans-Atlantic telecommunications cables and coastal facilities serving communities in southern Newfoundland. Despite the significance of this event, there is a limited understanding of the structural setting and neotectonics of the region. Imaging deep structures where the earthquake likely occurred is challenging, but shallow rift-related structures, influenced by deeper faults through structural inheritance, offer valuable insights into this deeper system. Here, we apply this concept through the analysis and interpretation of key regional faults on two-dimensional offshore seismic reflection data. Then, using slip tendency analysis, the reactivation potential of these structures under the present-day stress field was calculated. The analysis shows that regional NW-SE-striking normal faults, dipping at 40°– 60°, have high slip tendency values, offering insights into potentially active fault locations and geometries that support seismic hazard assessment and earthquake scenario modeling to assess impacts on populations and assets in southern Newfoundland.

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 it
