Global seismic monitoring data from the USGS indicate seven earthquakes of magnitude 5.5 or greater occurred worldwide between September 14 and 20, aligning closely with the market-implied 88% probability on that outcome. This count reflects standard background activity concentrated along major tectonic boundaries such as the Pacific Ring of Fire and mid-ocean ridges, without notable aftershock sequences or unusual swarms that would elevate totals. Historical weekly averages for events at or above this threshold typically range from six to ten, and the absence of significant model revisions or new observational clusters in the past week has reinforced trader consensus around seven or eight. Final USGS catalog verification, expected shortly, will confirm resolution criteria including precise magnitude thresholds and timing windows.
