Recent trader sentiment for weekly global M5.5+ earthquake counts centers on aftershocks from the August 10 Mw 7.4 Colombia event, which USGS data show as the period’s dominant signal alongside smaller independent quakes such as the M5.5 offshore El Salvador. Normal background rates produce roughly 5–10 events of this magnitude in any seven-day window, but the Colombia mainshock’s depth, location on an active subduction interface, and expected aftershock decay curve introduce meaningful variance around the 7–9 range. Model consensus from USGS and international catalogs indicates the sequence could add several M5.5+ events before August 16, while quiet periods elsewhere keep the upper tail modest. Resolution hinges on final NEIC catalog tallies through the weekend.

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 August 18, 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.
