Global seismic activity follows a roughly Poisson distribution with an average of 1–3 magnitude 6.5+ events per week, derived from USGS historical catalogs showing ~100–150 such quakes annually. This baseline, combined with high short-term variability from aftershock sequences and regional clustering, supports the market's strong preference for 0 (47%) or 1 (30.5%) events during the August 3–9 window. A 6.8 quake struck Japan on July 28 with no major ongoing aftershock sequences or subduction-zone alerts reported by monitoring agencies as of early August, leaving no clear catalyst for elevated rates. Upcoming USGS weekly summaries and real-time global catalogs will provide the primary data updates that could shift implied probabilities if new activity emerges.
