Trader consensus on Polymarket implies a weekly global tally around 8-9 magnitude 5.5+ earthquakes, aligning with USGS long-term averages of roughly 475 such events annually—or about 9 per week—derived from Gutenberg-Richter frequency-magnitude relations. As of April 16, three confirmed events have occurred since April 13: a M5.5 near Tonga on the 13th, another M5.5 in the Pagan region of the Northern Mariana Islands that day, and a M5.5 (preliminary M5.7) near Silver Springs, Nevada, on the 14th, per USGS catalogs. This early pace suggests 6-10 total by April 19, but inherent Poisson variability in global seismicity drives the spread, with subduction zones like the Pacific Ring of Fire contributing most. No active swarms or major aftershock sequences currently elevate risks; traders weigh random fluctuations against historical baselines, awaiting daily USGS updates through week's end for catalog refinements.

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 May 31, 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.
