Global seismic monitoring by the USGS shows a long-term average of roughly 10–15 magnitude 5.5 or greater earthquakes per week worldwide. With the September 14–20 window now past its midpoint and no major clusters reported along active plate boundaries or aftershock sequences, trader consensus has priced ≤6 events at 58.5% implied probability. This reflects the absence of unusual triggering factors such as recent large-magnitude quakes or volcanic unrest that could elevate rates. Remaining days hinge on standard background seismicity and any new model updates from continuous USGS and international networks, which could still shift outcomes toward the 7-event bin at 18.5% if activity increases.
