An earthquake scenario catalogue for Canada: a guide to using scenario hazard and risk results
Bibliographic record
Abstract
As part of the national Canadian Seismic Risk Model, a collection of earthquake hazard and risk scenarios has been created and will be documented in a series of Open Files and other publications. This first document will help a user in interpreting and understanding raw scenario outputs, without any technical, pre-requisite skills. A future document will help orient a technical user seeking to run their own earthquake scenarios, by introducing the input files and a strategy for running the OpenQuake (OQ) Engine for Canadian earthquake scenarios. Other documents will help nontechnical users interact with the model and understand how it can be used for disaster risk reduction in Canada. Following the first release of scenarios, tentatively scheduled for June 2021, all files will be accessed through the OpenDRR GitHub project page as they become available: <https://github.com/OpenDRR/earthquake-scenarios>. The raw scenario outputs, formatted as comma-separated value (csv) files, contain information about economic losses, building damage, casualties, and other disruptive impacts. All of the impacts are referenced to a unique asset ID, which can be tied to census geographic divisions or latitude/longitude coordinates for plotting. This paper documents all outputs of these models with sufficient detail for a user to begin exploring the results.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
