Traders assign a 99.5% implied probability to zero earthquakes of magnitude 6.5 or greater occurring worldwide between June 8 and June 14 because official USGS monitoring recorded no events meeting that threshold during the interval. Global seismic catalogs showed only lower-magnitude activity, consistent with typical background rates outside major subduction zones or aftershock sequences. This outcome aligns with the absence of significant tectonic triggers or swarm activity in high-risk regions during those seven days. A realistic challenge would require post-event magnitude recalibrations by USGS or discovery of an unreported deep or remote event exceeding the cutoff, though such revisions are uncommon once preliminary data are reviewed.
