Pattern of dynamic displacements in a strike‐slip earthquake
Bibliographic record
Abstract
Abstract High‐rate (1 Hz) records from GPS stations uniformly distributed along the fault ruptures of the 2014 Samothraki‐Gökçeada Mw6.9 earthquake in the North Aegean Trough, at the extension of the North Anatolian Fault Zone, were analyzed using the Precise Point Positioning (PPP) technique. Computed dynamic displacements shed light to the pattern of dynamic displacements during shallow strike‐slip earthquakes. The area of near‐field static seismic displacements bounds ramp‐type, long‐period dynamic displacements (fling steps) in the sense of static displacements. Along‐fault and normal to fault components of dynamic displacement follow typical attenuation laws, but attenuation is higher in the fault‐parallel component hence confined to the area of static dislocations. Forward directivity and local, especially topography‐controlled amplification effects, consistent with accelerometer evidence, were also observed. The overall pattern seems to characterize shallow strike‐slip earthquakes and is expected to prove useful to explain or even predict the near‐field damaging potential of strike‐slip earthquakes.

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.
