Trader consensus implies a 90% probability of no magnitude 8.0 or greater earthquake worldwide by June 30, 2026, per USGS data, reflecting the extreme rarity of such megaquakes—typically one to two annually—and the absence of detectable short-term precursors amid moderate global seismicity. A magnitude 7.7 subduction zone event off Japan on April 20 elevated perceived risks, prompting a brief Japan Meteorological Agency advisory citing a 1% chance (10 times normal) of an M8+ along the Japan Trench in ensuing days due to stress changes; however, the advisory expired without escalation, steadying odds. USGS aftershock forecasts and real-time monitoring show no anomalous activity, with resolution hinging on their significant earthquake catalog through month's end.
