Global seismic activity shows substantial week-to-week variability driven by the random timing of tectonic events along major plate boundaries, aftershock sequences following larger quakes, and occasional clusters in subduction zones or transform faults. USGS data indicate roughly 25 magnitude 5.0+ events occur worldwide each week on average, with those at 5.5 and above typically numbering in the single digits to low teens depending on background rates and any triggered seismicity. The broad market distribution, with ≤6 at 31% and outcomes spread through 13+, reflects this inherent unpredictability over a seven-day window, as new monitoring data or an unexpected M6+ event could quickly shift counts. Traders weigh ongoing global catalogs against historical baselines while awaiting real-time USGS updates.
