Global seismicity patterns, tracked by USGS monitoring, show an average of 6–8 magnitude 5.5+ earthquakes occurring worldwide each week, driven by ongoing tectonic stress release along subduction zones and transform faults. The broad distribution of market-implied odds, peaking at >9 events, captures the high week-to-week variability from aftershock sequences that can rapidly elevate counts, as well as the possibility of quiet periods when no large mainshocks occur. Key variables include clustering near the Pacific Ring of Fire, recent volcanic unrest that sometimes precedes seismic swarms, and the limited predictability of individual events on short timescales. New USGS catalog updates in the coming days will clarify whether current background rates trend toward the middle or upper end of historical ranges.

The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program, with the minimum magnitude set to 5.5 and the date parameters set to the relevant dates for this market's timeframe (https://earthquake.usgs.gov/earthquakes/search/).
If an earthquake of substantial size has occurred within this market's timeframe but not yet appeared on the resolution source, this market may remain open until June 30, 2026, 11:59 PM ET, or until the earthquake in question otherwise appears on the resolution source. If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used.
This market may not resolve until the timeframe of this market has concluded. If a qualifying earthquake has been recorded on the final day, this market may remain open for 24 hours to allow for revisions to the recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.
