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.
