Global seismic activity monitored by the United States Geological Survey shows that magnitude 6.5 or greater earthquakes occur at an average rate of roughly one to two per week worldwide, driven by ongoing tectonic plate motions along major fault zones. This statistical baseline underpins the current market-implied odds favoring zero or one event in the May 18-24 period, as short-term clusters remain uncommon without preceding large mainshocks or aftershock sequences. Recent global observations have reflected typical background levels with no widespread unusual swarms or elevated strain indicators from monitoring networks. Resolution depends strictly on verified magnitudes and timing within the exact seven-day window, with new data releases from official catalogs able to shift probabilities quickly if activity spikes.
