Recent seismic data indicate subdued global activity for M5.5+ events during September 14–17, with only a handful recorded, including M5.6 and M5.5 events offshore Indonesia on the 14th and isolated M5.3–M5.1 shocks near Tonga and the Northern Mariana Islands. USGS and EMSC catalogs show most recent events clustered below the 5.5 threshold along Pacific Ring of Fire subduction zones, consistent with typical weekly variability around long-term averages of roughly 8–12 such quakes. Trader consensus favoring ≤6 events reflects this early-week pace and limited aftershock sequences, though remaining days through September 20 allow for potential escalation if new clusters emerge near active faults.

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 48 hours after the market's closing time, 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 time, this market will resolve according to the data published at that time.
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.
If no earthquake data for this market's timeframe has been published on the resolution source by 48 hours after the market's closing time, this market will resolve to the lowest bracket.
