Pre-Seismic Quiescence Detected by K–R Critical Slowing-Down Indicators: Independent Replication in Japan and Chile Subduction Zone Catalogs
Researchers introduced the K‑R excitation‑regulation framework, an ODE‑based system that extracts Critical Slowing‑Down (CSD) indicators from rolling earthquake magnitude windows. Applying it to USGS catalogs in Japan (14,501 events) and Chile (9,150 events) revealed a consistent pre‑seismic CSD₅₀ suppression of roughly 18‑22% across four days before M≥6.0 mainshocks, surviving multiple statistical corrections. Synthetic tests showed variance reduction, not rate decline, drives the signal, while traditional b‑value analyses showed no change. The authors caution that the finding is diagnostic, not a deterministic forecasting tool.
Are Humans Degenerating Genetically and Getting Dumber as a Result?
