Trader consensus on Polymarket implies around 9-10 global earthquakes of magnitude 5.5 or greater for April 13-19, with >9 leading at 36.5% amid a historically typical weekly baseline of roughly 10-12 such events per USGS monitoring data. As of April 16, USGS has cataloged at least four qualifying quakes: M5.5 off Tonga on April 13, M5.5 in the Pagan region of the Northern Mariana Islands that day, M5.7 near Silver Springs, Nevada on April 14 UTC (triggering a swarm of smaller aftershocks), and an M5.7 in Costa Rica on April 15. This early-week pace aligns with moderate global seismic activity concentrated along Pacific Ring of Fire subduction zones, where tectonic plate interactions drive frequent moderate events. Inherent Poisson-like clustering introduces uncertainty, but no anomalous quiet periods or major suppressors like aftershock decay are evident; continuous USGS real-time feeds will update counts through April 19 resolution.
