Abstract

fetched live from OpenAlex

In this paper, the characteristics of focal precursors, field precursors of subsurface liquid before the moderately strong earthquakes and the remote precursors before the strong earthquakes are analyzed. The results show that the focal precursors of moderately strong events occurred 1 2 years before the moderately strong events, most of synchronous anomalies of major observational items occurred at the observational sites, the reverse or turning the anomalies might occur imminently before the moderately strong events and recovered after the events. Most of the field precursors are expressed as change of the short term anomalies at a few observational sites rather than all the sites, while the field precursors of strong earthquakes occurred at a few observational sites, where only some observational items with good earthquake reflecting capacity show synchronous medium term anomalies. The remote precursors of strong earthquakes (or earthquake swarm) are mainly expressed as the precursory anomalies of few observational items with good earthquake reflecting capacity. The cause of earthquake precursors is also preliminarily discussed.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
