USGS historical data shows global earthquakes of magnitude 6.5 or greater (moment magnitude scale) occur at a rate of roughly 0.6 per week on average, following a Poisson distribution that implies about 55% probability of zero events in any seven-day span—aligning closely with traders' 51% consensus on zero for March 23-29. This baseline dominates sentiment, as no unusual seismic swarms, aftershock sequences, or tectonic stress indicators from plate boundaries like the Ring of Fire have emerged recently to elevate risks. Real-time USGS monitoring confirms none so far this week, with next updates from global networks likely influencing shifts toward 1 (32.5%) if minor activity builds, though models show low odds exceeding two absent a major rupture.
