USGS data records five magnitude 7.0+ earthquakes worldwide from January 1 through May 13, 2026—including a M7.1 near Sabah, Malaysia on February 22, M7.5 off Tonga on March 24, and M7.4s near Indonesia (April 1) and Japan (April 20)—slightly above the historical average of about 1.25 events per month driven by subduction zones along the Pacific Ring of Fire. This tally positions the 8+ outcome at 80.5% implied probability, as trader consensus anticipates 3–4 more in the remaining 6.5 weeks per long-term seismicity rates, while 7 at 18.9% reflects Poisson-distributed uncertainty in great earthquake occurrence. No events in early May signal typical variability; continuous USGS catalog updates will refine monitoring through June 30 resolution.
