Estimation of the landslide source for the 1929 Grand Banks event using a deep-sea landslide tsunami simulation
Bibliographic record
Abstract
SUMMARY The 1929 Grand Banks earthquake (Mw 7.1) generated a large landslide that broke submarine cables near the source area. A large tsunami was generated by the large landslide that killed 28 people on the southern coast of the Burin Peninsula, Canada. The tsunami was also observed at a tide gauge in Halifax, Canada. In this study, the initial landslide mass distribution was estimated by fitting the first pulse of the tsunami waveform observed at Halifax and the timings of the submarine cable break with those computed values. A deep-sea landslide tsunami computation method was developed by modifying a previously developed Tsunami Squares method with a different friction term and an effect of deep water. The results showed that the tsunami waveform and timing of the cable break were well explained by the tsunami computed from the initial landslide mass volume of about 450 $\mathrm{km^3}$ located along the continental slope near the source area. The method developed to compute deep-sea landslide tsunamis should be useful for studying other types of landslide tsunamis.

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.
