Global seismic rates for magnitude 5.5+ events typically average 8–12 per week, driven by steady tectonic strain release along major plate boundaries, with natural Poisson-like variability explaining the close clustering of market-implied odds around 7–13. Recent M7.7 and M7.4 events in Indonesia and Colombia have initiated aftershock sequences that USGS monitoring shows can add several 5.5+ tremors within days, elevating the potential for higher weekly totals while low-activity periods, as observed mid-August, support the ≤6 outcome. Traders weigh these against ongoing aftershock decay rates and the absence of new large mainshocks in high-risk zones like the Pacific Ring of Fire. Upcoming USGS daily catalogs through August 23 will resolve counts based on precise magnitude thresholds and global detection completeness.
