Global seismic monitoring by the USGS shows M6.5+ earthquakes occur at an average rate of roughly 15–20 events per year worldwide, or about 0.3–0.4 per week, driven by tectonic plate motions along subduction zones and transform faults. Recent activity, including a M7.4 event in Colombia on August 10 and a M6.0 in the South Sandwich Islands on August 12, illustrates clustering potential but does not alter the baseline Poisson-like distribution for the August 17–23 window. Market-implied odds favoring zero or one event reflect this inherent variability, model uncertainties in short-term forecasting, and the absence of elevated aftershock sequences or unusual strain indicators in major seismic zones.
