ShakeMap for the MN 5.4, 6 March 2005 Riviere-du-Loup, Quebec Earthquake
Bibliographic record
Abstract
Since the beginning of June 2004, near-real-time ShakeMaps have been produced in Ontario for earthquakes of M > 2.8 and are posted at http://www.shakemap.carleton.ca/ within minutes of occurrence. ShakeMaps, originally conceived by Wald et al. (1999), provide rapid online assessment of locations, shaking intensities, and expected levels of damage to specific areas, The Nuttli magnitude ( M N ) 5.4 earthquake which occurred 17 km southwest of Riviere-du-Loup, Quebec on 6 March 2005 was the first moderate, well recorded event since the implementation of the Ontario ShakeMap project. It provided a good opportunity to evaluate the performance of ShakeMap in eastern Canada. The ShakeMap location and moment magnitude, based on the ground-motion centroid, are very close to traditional estimates of these parameters. ShakeMap intensities agree with the preliminary observed intensity results collected based on felt reports submitted online. Recorded ground-motion parameters from this earthquake agree very well with the predictions of empirical ground-motion relations developed for ShakeMap applications by Kaka and Atkinson (2005a), as well as with relations developed by Atkinson and Boore (1995).

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.
