Abstract

fetched live from OpenAlex

THE “GRAND BANKS” EARTHQUAKE occurred at 1702 (Newfoundland Standard Time [NST]) on Monday, November 18, 1929. It was centred eighteen kilometres beneath the Laurentian Continental Slope, 265 kilometres south of Newfoundland’s Burin Peninsula, in 2,000 metres of water. The event had a surface wave magnitude of Ms = 7.2 2 and it was felt as far afield as New York City and Montreal; there is even a serendipitous felt-report in Bermuda. 3 Onshore the damage from the earthquake’s shaking was restricted to some slumping and minor building damage in Cape Breton Island; Newfoundland, despite its proximity to the epicentre, experienced no physical damage, other than broken crockery shaken off shelves, because most structures were of wood-frame construction built on solid substrates. On the ocean floor offshore, part of the Laurentian Slope was shaken loose and began an underwater landslide that went on for hours, and flowed at least 1,100 kilometres out onto the floor of the 5,000-metre-deep Sohm Abyssal Plain. It was 23 years before scientists recognized the landslide and its great importance as a dominant ocean process. 4 The 1929 “turbidity currents” moved at speeds of 50 to 70 knots (93-130 km/s) and cut twelve trans-Atlantic telegraph cables in about 28 places. Repairs involved every available cable ship in the Atlantic and continued until August 1930. 5 About 200 cubic kilometres of material was removed over an area of 20,000 square kilometres 6 of the continental slope and rise.

Full frame distilled prediction

Teacher imitation

Not 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.
