Trader consensus on Polymarket prices 8+ magnitude 7.0+ earthquakes worldwide by June 30 at 56.5%, driven by USGS historical data showing an average of 16 such events annually—implying about 8 in the first half-year—despite only two recorded so far this year: a deep M7.0 offshore Sabah, Malaysia on February 22 and an M7.5 near Tonga on March 24. Seismic activity follows a Poisson distribution with inherent clustering risks along subduction zones like the Tonga Trench, where recent Tonga event occurred amid elevated Ring of Fire rumblings. With 94 days remaining, USGS monitoring highlights steady global rates from plate tectonics, though no short-term forecasts exist; updated catalogs and regional swarms could shift probabilities further.
