USGS seismic catalogs confirm just five magnitude 7.0+ earthquakes worldwide through May 13, 2026—M7.1 off Sabah, Malaysia (Feb. 22), M7.5 off Tonga (March 24), M7.3 off Vanuatu (March 30), M7.4 off North Maluku, Indonesia (April 1), and M7.4 off Iwate, Japan (April 20)—positioning ≤8 as the market-implied frontrunner at 46.5% amid a below-average pace versus the historical global rate of 15–20 such events annually. No M7+ quakes have struck in the past 23 days, reflecting stable tectonic activity along major plate boundaries without notable foreshock clusters or strain anomalies in USGS monitoring. With 48 days remaining to June 30, traders anticipate 2–5 more based on Poisson-distributed historical patterns, concentrating odds on 9 (29%) and 10 (31.5%) while pricing 14+ below 3%; continuous real-time USGS updates could shift sentiment if subduction zones like the Pacific Ring of Fire activate.
