Scaling relations of seismic moment and rupture area for outer-rise earthquakes
Bibliographic record
Abstract
Abstract A new piece-wise scaling relation for rupture area ( S ) and seismic moment ( M 0 ) was obtained for outer-rise earthquakes using data compiled from previous seismological studies. The compiled source parameters were examined carefully to ensure that rupture area dimensions represent the "actual" rupture area. Twenty sets of S and M 0 pairs for ten earthquakes from independent studies were used for regression analysis. To estimate rupture areas of outer-rise earthquakes whose fault down dip tips, respectively, do and do not reach the oceanic lithosphere base, regression parameter b in S=(M 0 /a) 1/b is 2 with the corresponding regression parameter log 10 a 2 being 1.402 (±0.250), and b is 1.5 with the corresponding regression parameter log 10 a 1 being 6.401 (±0.187). The piece-wise scaling relation developed here can fit outer-rise earthquake data from Mw 7.2 to Mw 8.4 and can be used to estimate rupture areas of earthquakes greater than Mw 8.4.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
