**A magnitude 5.6 earthquake recorded 74 km ESE of Kokopo, Papua New Guinea, at approximately 14:08 UTC on September 26 stands as the day's largest event according to USGS and EMSC data.** This moderate, intermediate-depth quake aligns precisely with the market's dominant 5.5–5.6 bin, which commands 96.9% implied probability. No larger events appear in official catalogs for the 24-hour window, consistent with typical daily global seismicity where M5+ quakes occur several times but M6+ events remain infrequent. Trader consensus reflects verified observational data rather than forecasts. Revisions to magnitude estimates, discovery of an unreported larger event in a remote region, or reclassification of aftershock sequences could theoretically shift resolution, though current multi-agency confirmation makes such outcomes unlikely.
