The market's leading position for zero events stems from USGS global monitoring showing no magnitude 6.5 or greater earthquakes in recent weeks, consistent with baseline tectonic rates. Worldwide, roughly 15 to 20 such quakes occur annually on average, yielding a statistical expectation of well under one per seven-day interval and favoring low counts absent unusual clustering along major fault systems. Recent observational data confirm steady but moderate seismic activity, with the strongest events in the past month remaining below the 6.0 threshold and no evident aftershock sequences or subduction-zone surges. Traders assess the outlook through ongoing USGS catalogs, where any new detections before the period closes could adjust implied probabilities for one or two events.
