The Source Rupture Models and Seismogenic Structures of the Iran 2017 MW 7.3 Earthquake
Bibliographic record
Abstract
The 12 November 2017 MW 7.3 Iran earthquake was further studied. By analyzing Rayleigh-wave dispersion data, crustal models in the surrounding of the epicenter were obtained. It was found that there are high-velocity layers over a low-velocity zone. Using the obtained crustal models and a grid search procedure, the initial rupture depth of about 16.4 km and the rupture propagation velocity of about 1.62 km/s were retrieved. The source rupture models were established using the obtained rupture initial depth and the rupture velocity. The key features are as follows: The earthquake occurred on a shallow dip-angle fault, with ruptures spanning high-velocity layers in a depth range of approximately 7–25 km. A noteworthy observation from comparing crustal and rupture models is the existence of a low-velocity zone (layers) beneath the major rupture region (below about 25 km). It was realized that the seismogenic structure of this earthquake showed that high-velocity layers lay a low-velocity zone in the Zagros mountain seismic belt.

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.
